[6][21][22], Along southeastern coasts of Brazil, whales add twisting movements to lunge feeding. Bryde’s whales have one more ridge in front of their blowholes than the sei whale's two. Bryde's whales use different methods to feed in the water column, including skimming the surface, lunging, and creating bubble nets. The Bryde's whale swims unpredictably and often changes route and direction for no apparent reason. "Review of the Occurrence of the Bryde's Whale in the Northwest Pacific". Being a member of the baleen suborder, the Bryde’s whale does not have teeth, but instead it has baleen plates with bristles on them, which enable the filtering of prey from the water. [17] Based on the stomach contents of Bryde's whales caught by Japanese pelagic whaling expeditions in the North Pacific in the 1970s, the majority where found to feed on euphausiids (nearly 89%), whereas only about 11% fed on fish. The former was caught off northeastern Honshu and eastern Hokkaido, while the latter was taken off western Kyushu and southern Honshu. [3] Also, a smaller, coastal form of B. brydei is found off southern Africa, and perhaps another form in the Indo-Pacific differs in skull morphology, tentatively referred to as the Indo-Pacific Bryde's whale. [6], Their blow is columnar or bushy, about 3.0–4.0 m (10–13 ft) high. [6] They are more active on the water surface than sei whales, especially in coastal waters. Bryde's whale is listed on Appendix II[59] of the Convention on the Conservation of Migratory Species of Wild Animals. The Northern Gulf of Mexico Bryde’s whale is currently threatened by collisions with vessels, acoustic disturbance from seismic airguns and other oil and gas-related activities, military activities, vessel noise, oil spills, and pollution. Brydes whales eat an estimated 1,320 to 1,450 pounds of food per day. Bryde’s whales in tropical waters may breed throughout the whole year, while in sub-tropical seas breeding mainly takes place in autumn. Bryde's whales are unique among other whales with their generalist diet, which enables them to stay year-round in warm waters where they can always find food. When diving for food, Bryde's whales can stay underwater for as long as 20 minutes before coming up for air. There habitat is mainly warm-temperate and tropical waters Their diet consists of pilchard, mackerel, herring, anchovies, shrimp, crabs, and lobsters and sometimes octopus, squid, and cuttlefish. The Bryde's whale usually chooses to feed alone, except for mothers and calves, who often feed together. 2003), was formerly thought to be a pygmy form of Bryde's, but is now recognized as a distinct species. [31] Resident or semi-resident groups also exist off Hawaiian[32] and Northwestern Hawaiian Islands,[citation needed] and Northern Mariana Islands. In 1997, an estimated over 20,000 Bryde's whales had been caught in the western North Pacific between 1911 and 1987 (the Japanese were later found to have falsified their reported take from the Bonin Islands between 1981–87, reporting a catch of only 2,659 instead of the true take of 4,162). [13] It is often frayed or ragged along its rear margin and located about two-thirds of the way along the back. Artisanal whalers have taken them off the coasts of Indonesia and the Philippines. Omura's whale or the dwarf fin whale (Balaenoptera omurai) is a species of rorqual about which very little is known. Omura, Hidero. In the Hauraki Gulf all three can be found at different times of the year – Auckland’s productive waters are great for hungry whales! In the southwestern Pacific, they occur as far south as the North Island of New Zealand. Their gestation period is estimated at 12 months. Those of the southern Indian Ocean appear to correspond to B. brydei, as do the individuals illegally caught by the Soviets in the 1960s in the northwest Indian Ocean, as well as the Maldives.

[7][8], In the 1950s it was discovered that there were two types of "sei whale" off Japan, a northern form with longer, finer baleen and shorter ventral grooves and a southern form with shorter, coarser baleen and longer ventral grooves. Prior to 2006, only two confirmed sightings of Bryde's whale had been reported in the eastern North Pacific north of Baja California—one in January 1963, only a kilometer off La Jolla (originally misidentified as a fin whale), and another in October 1991 west of Monterey Bay. [23], In the Pacific and northern Indian Ocean, Bryde's whales have been observed employing "tread-water feeding" or "trap feeding,"[24] a behaviour more commonly known from the northern Gulf of Thailand which is also performed by humpback whales in the northeastern Pacific. [6], In March 2019, a diver off the coast of South Africa was accidentally caught in the mouth of a feeding Bryde's whale. The dorsal fin is positioned far down the back. 2011, "Twisting movements during feeding behavior by a Bryde's whale (Balaenoptera edeni) off the coast of Southeastern Brazil.pdf", "Trap-Feeding – A new humpback feeding behaviour! Bryde’s and sei whales have a more varied diet, feeding on multiple different types of food including plankton, crustaceans (such as krill) and fish. Gestation lasts 11 to 12 months. As with the other large baleen whales, Bryde’s whales eat comparatively microscopic prey, mostly consisting of plankton, krill and copepods (tiny crustaceans). Norwegian factory ships off Baja California took an additional 34 Bryde's whales between 1924–29;[61] two were also caught off central California in 1966. The mother nurses for 6–12 months.[6]. In Japan, early whalers called it "anchovy" (鰯, iwashi) or "skipjack whale" (鰹鯨, katsuo-kujira カツオクジラ). Species Fact: Bryde's whales are named for Johan Bryde, a Norwegian man who built the first whaling stations in South Africa. "Middle sized balaenopterid whale specimens (Cetacea: Balaenopteridae) preserved at several institutions in Taiwan, Thailand and India". The 35- to 50-foot marine mammals can be found in warm waters in the Atlantic, Pacific and Indian … The American Cetacean Society (ACS) was founded in 1967 and is recognized as the first whale, dolphin, and porpoise conservation group in the world. Before its formal description, it was referred to as a small, "dwarf" or "pygmy" form of Bryde's whale by various sources. "Prey consumption and feeding habits of common minke, sei and Bryde's whales in the western North Pacific". [9] A later study revealed that Bryde's caught off Japan exhibited lateral ridges on their rostrum, whereas sei whales lacked this feature. edeni. In addition, Bryde's whale is covered by the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU).[60]. The prey differed by location and season. Modern whaling for Bryde's whales is thought to have begun from coastal stations in Japan in 1906, where it continued uninterrupted until 1987—they were also caught offshore in the western North Pacific by both Japanese (1971–79) and Soviet (1966–79) fleets, as well as from Taiwan (1976–80), the Bonin Islands (1946–52 and 1981–87), and the Philippines (1983–85). (2012). [55] As of 2016, the Bryde's whale is considered to be critically endangered in New Zealand as there are approximately 200 left in the wild.[56]. B. brydei gets its specific and common name from Johan Bryde, Norwegian consul to South Africa, who helped establish the first modern whaling station in the country, while B. edeni gets its specific and common names from Sir Ashley Eden, former High Commissioner of Burma (Myanmar). Between August 2006 and September 2010, six sightings were made by scientists in the Southern California Bight. Like other rorquals, it has no teeth, but has two rows of baleen plates. Historically, this species was not significantly targeted by commercial whalers, but became more important in the 1970s as the industry depleted other targets. Members of the Bryde's whale complex are moderately-sized rorquals, falling behind sei whales, but being larger than Omura's whale and the relatively small minke whales. In general, data are insufficient to determine population trends. New Great Whale: Eden’s Whale in Sri Lankan Waters? (1999). They are remarkably elongated (even more so than fin whales), with the greatest height of the body being one seventh their total length—compared to 1/6.5 to 1/6.75 in fin whales and only 1/5.5 in sei whales. SC/56/PF15. [28][29][30] Mitochondrial DNA analysis showed that Bryde's whales caught in the pelagic western North Pacific and Bonin Islands (resident population), as well as biopsy samples taken from whales off Hawaii, the west coast of Baja California, and the southern Gulf of California, belonged to B. # Bryde’s Whale The petition stated that the GOMx Bryde's whale is endangered based on at least three of the five section 4(a)(1) factors: Present or threatened destruction, modification, or curtailment of habitat or range; inadequacy of existing regulatory mechanisms; and other natural or manmade factors affecting its continued existence… [33] Bryde's whales do not occur within central to northern Sea of Japan on regular basis or at least in large numbers. Status:Lower risk. The Bryde's whale is a baleen whale, more specifically a rorqual belonging to the same group as blue whales and humpback whales. Diet As baleen whales, this species feeds on tiny fish and krill, or plankton. They also differed in the shape of the palate. [5] In 1950, the Dutch scientist G.C.A. Of the two species, Bryde’s whales may also be more active on the surface, often with On September 18, 2014, we received a petition from the Natural Resources Defense Council to list the Gulf of Mexico population of Bryde's whale (Balaenoptera edeni) as an endangered species. They have also been reported in an upwelling area off Chile between 35° and 37°S. They are sometimes killed or injured by ship strikes. Bryde's whales closely resemble their close relative the sei whale. They become sexually mature at 8–13 years of age, when females are 12 m (39 ft). [45] It is unknown whether eight small individuals—reaching only 11.2 to 11.7 m (37 to 38 ft) at maturity—caught off western and eastern Australia between 1958 and 1963 are specimens of B. edeni or B. They were first recorded in the Azores in 2004 and showing mixed traits of offshore and inshore forms,[36] but do not occur in the Mediterranean Sea (regarding the bones of a baleen whale found, Bryde's whale was listed as one of suggested species[37]). After weaning, the mother leaves her calf to look after itself. [6], In 1878, the Scottish zoologist John Anderson, first curator of the Indian Museum in Calcutta, described Balaenoptera edeni, naming it after the former British High Commissioner in Burma, Sir Ashley Eden, who helped obtain the type specimen. They are dark gray in color with a cream belly. For management purposes, the U.S. population is divided into three groups: the Eastern Tropical Pacific stock (11,000–13,000 animals) and the Hawaiian stock (350–500) and an endangered stock of about 100 whales in the Gulf of Mexico. Luksenburg, Jolanda A. and George Sangster. There is not much information about the mating habits of Bryde's whales, though they probably are similar to other related cetaceans. Over 2,000 were caught off Cape Province, South Africa, from 1911–67, most (1,300) during 1947–67. The population may include up to 90,000–100,000 animals worldwide, with two-thirds inhabiting the Northern Hemisphere. They often make moaning sounds. brydei. What do they eat? [濒危物种数据库 - 鳀鲸 Balaenoptera edeni Anderson, 1879]. Gulf of Mexico Bryde's Whales, "DNA barcoding of the Bryde's Whale Balaenoptera edeni Anderson (Cetacea: Balaenopteridae) washed ashore along Kerala coast, India", "Rare whale footage shot by drone thanks to AUT scientists", "South African diver Rainer Schimpf swallowed by Bryde's whale", "Diver survives after being scooped up in whale's mouth off South Africa", "Thai minister warns tourists of harsh penalty if found disrupting Bryde's whale", Bryse's whales (Balaenoptera cf. [15], Bryde's whales have an upright, falcate dorsal fin that is up to 46.25 cm (18.21 in) in height, average 34.4 cm (13.5 in), and is usually between 30 and 37.5 cm (11.8 and 14.8 in). (2007). A Bryde's whale is believed to consume food of about 1,320-1,450 lbs (600-660 kg) per day, about 4% of its body weight. In. A population found off southern and southwestern Japan in the East China Sea has also been referred to B. edeni. Sometimes, they blow or exhale while under water. The former mainly feed on anchovies (Engraulis capensis, 83%), maasbankers (Trachurus trachurus, 36%), and pilchards (Sardinops ocellata, 33%), with only one (or 3%) being found with euphausiids (Nyctiphanes capensis). Bryde's Whale is dark gray with a yellowish white underside. 7. [6], Bryde's whales feed on a wide variety of fish, planktonic crustaceans, and cephalopods. Balaenoptera brydei has yet to be evaluated. The Bryde’s whales prefer tropical and temperate waters to the polar seas that other whales in their family prefer. (1977). Their blow is columnar or bushy, about 3.0–4.0 m (10–13 ft) high. Bryde's whales can easily be confused with sei whales, though they are smaller and inhabit warmer waters. After a thorough exam, biologists trucked it across the state for a temporary burial at the Pinellas County park. B. brydei occurs in the Atlantic, Pacific, and Indian Oceans between the 40th parallels of latitude, preferring highly productive, tropical, subtropical, and warm, temperate waters of 16–22 °C (61–72 °F). DIET Bryde’s Whales are considered opportunistic feeders targeting pelagic crustaceans and fish (e.g., herring, anchovies, mackerel), or cephalopods without a clear preference. Reynolds, John Elliott, and Sentiel A. Rommel. Bryde's whales display seemingly erratic behaviour compared to other baleen whales, because they surface at irregular intervals and can change directions for unknown reasons.[6]. [62], An estimated 5,542 Bryde's whales were caught off Peru between 1968 and 1983, including a reported catch of 3,589 between 1973 and 1983. (2004). [58], It is listed in Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix I, which prohibits international trade. 西部北太平洋、特に南西部日本沿岸におけるニタリクジラの資源生態学的研究 木白 俊哉. The two genetically distinct, candidate species/subspecies/morphologies are Bryde's whale B. brydei and the Sittang or Eden's whale B. edeni,[5] that differentiate by geographic distribution, inshore/offshore preferences, and size. Bryde's whales (, This page was last edited on 30 November 2020, at 01:08. [63] The peak reported catches were reached in 1973–74 and 1974–75, when over 1,800 were taken each year. RIGHT: Corvus unicolor, the long-lost Banggai Crow, was rediscovered on Indonesia's Peleng Island. Drone footage from Auckland University of Technology shows rare Bryde's whale off the coast of New Zealand. Goto, M., Kanda, N., & Pastene, L. A. Bryde’s whale have a varied diet, feeding on multiple different types of food including zooplankton (including krill) and fish. [10], In the 1960s it was discovered that some of the "sei whales" being caught off Brazil were also Bryde's whales based on the same characters that distinguished the two species off Japan (i.e. It preys on the anchovy and it was commonly associated with the skipjack. They are now called nitari-kujira (似鯨, "look-alike whale"), for their resemblance to the sei whale. [16] When submerging, these whales do not display their flukes. "Middle-sized balaenopterid whale specimens in the Philippines and Indonesia". The Bryde’s whale (pronounced broo-dess) is also known as the tropical whale because it is the only baleen whale species that lives year-round in warmer tropical waters. In order to maintain their diet these marine mammals are found in areas that have abundant supplies of food. The largest measured by Olsen (1913) was a 14.95 m (49.0 ft) female caught off Durban in November 1912,[5] while the longest of each sex measured by Best (1977) at the Donkergat whaling station in Saldanha Bay, South Africa, were a 15.51 m (50.9 ft) female caught in October 1962 and a 14.56 m (47.8 ft) male caught in April 1963; both were the offshore form. In the North Pacific, they occur as far north as Honshu to the west and southern California in the east, with vagrants reported as far north as Washington in the United States. Recently, Duke University researchers estimated abundance to be 44 individuals based on the averages of 23 years of survey data. Individuals of the inshore form off South Africa are also resident year-round, occurring mainly between Cape Recife and Saldanha Bay, whereas the larger offshore form migrates to West African equatorial waters in the winter. [18], Off South Africa, prey preferences differed between the inshore and offshore forms. Further studies on the external characters", "Further information on Bryde's whale from the coast of Japan", "Bryde's whale occurs on the coast of Brazil". Yamada, T. K., T. Kakuda & Y. Tajima (2008).

At birth, they are 3.95–4.15 m (13.0–13.6 ft). The bodies are very sleek and they have a close resemblance to the sei whale. three ridges on the rostrum versus one, shape of the palate, texture of the baleen, length of the ventral grooves). "Molecular identification of the first Bryde's whale (, 中华人民共和国濒危物种科学委员会. Eden's Deputy Commissioner, Major A.G. Duff, sent a Mr Duke, one of his assistants, to Thaybyoo Creek, between the Sittang and Beeling Rivers, on the Gulf of Martaban, where he found a 37-foot whale, which had stranded there in June 1871 after swimming more than 20 miles up the creek—it was said to have "exhausted itself by its furious struggles" to get free and "roared like an elephant" before finally expiring. [43], Distribution of the group in Gulf of Mexico has been restricted in a very small area unlike the original range occupying throughout the gulf, and the total abundance is estimated to be from 33 to 44 or around 100 individuals. (1878). Their diet consists of krill, copepods, red crabs, shrimp, as well as a variety of schooling fishes, such as herring, mackerel, pilchards, and sardines. The flippers are small and slender. They occur in the Gulf of Mexico and throughout the wider Caribbean—two specimens from Aruba were found through mtDNA analysis to be firmly placed within B. brydei and to form a clade with a specimen from Madeira and individuals of the offshore form of South Africa. Calves are about 3.4–4.0 m (11–13 ft) long at birth and weigh 1,000 kg (2,200 lb). confused with other baleen whales, particularly sei whales. [28][29][46] Along Chinese coasts, for example, whales were once thought to be abundant along southern coasts from Fujian and Guangdong Provinces to Hainan Island and the north-eastern tip of the Gulf of Tonkin[47][48][49][50][51] such as off Tieshangang District[52] and around Weizhou and Xieyang Islands.[53][54]. Bryde’s whale sightings in the Gulf of Mexico are rare, as are strandings. Individuals sighted in the Red Sea may or may not be B. Over 30,000 Bryde's whales were caught between 1911 and '87, including over 1,400 taken by the Soviets in the Southern Hemisphere from 1948–73 (only 19 were reported). Bryde’s Whale (Balaenoptera edeni) Group formation: Solitary (mother-calf pair or larger feeding groups up to 20) Size: males 12-15 m, females 12-16 m, calf 4 m Weight: ca. These are hair-like structures that sieve the water and trap small fish and krill in the plates. Common Bryde’s whale, Eden’s whale, Pygmy Bryde’s whale, Tropical whale. The latter, however, mainly feed on euphausiids (primarily Euphausia lucens, but also E. recurva, N. capensis, and Thysanoessa gregaria), as well as various deep-sea fish (including Mueller's pearlside, Maurolicus muelleri, and a species of Lestidium). Incidentally, anchovies are dominant prey for both species off Japan. Diet. [7] In 1913, the Norwegian scientist Ørjan Olsen, based on the examination of a dozen "sei whales" brought to the whaling stations at Durban and Saldanha, in South Africa, described Balaenoptera brydei, naming it after the Norwegian consul to South Africa Johan Bryde. 40 t, calf 1 t Spout: 3-4 m Age: 40-70 yrs Sexual maturity: 8-11 yrs Gestation: 11-12 mths, with 2 yrs in between Weaning: 6-7 months Diet: Fish, planktonic crustaceans, and cephalopods. Distribution: Bryde's Whale Range. [28][35], In the North Atlantic, they have been recorded as far north as Cape Hatteras. They are mostly encountered in waters above 16°C, in both offshore and coastal areas. A whale stranded in Hong Kong and another saved from a river in eastern Australia were found to be closely related to the Junge specimen and the East China Sea whales. The sei whale, like other rorquals, has a single median ridge, as well as a slightly arched rostrum, which is accentuated at the tip. Sittang whale refers to the type locality of the species. Blue whales are known for feeding on krill. These were sent to Anderson, who described the specimen, which was physically mature, as a new species. It has been observed that the same individuals switch preys between years and feeding areas, probably following the … It is listed on Appendix II[59] as it has an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. Bryde's whales have not been reported as taken or injured in fishing operations. 7. One was even found "full of baby squid" (later identified as Lycoteuthis diadema). [6] They sometimes generate short (0.4 seconds) powerful, low-frequency vocalizations that resemble a human moan. Bryde's whale (most had auxiliary ridges) of small size—estimated at 10.1 to 11.6 m (33 to 38 ft) in length—sighted off the northeastern side of the Solomon Islands during a survey in late November and early December 1993 may be referable to B. edeni. Soon after the whale submerged again, it quickly spit Schimpf (who was unharmed) back out and swam away. Sometimes known, appropriately, as the “tropical whale”, this is the only baleen whale species that lives all year-round in warmer waters near the equator. Bryde's whales are unlike other whales because they have a generalist diet, which allows them to stay in warm waters year-round where they can always find food. brydei/edeni). Based on osteological features, a specimen from Taiwan was referred to B. brydei, while several specimens from the Philippines and Indonesia differed slightly in skull morphology and were referred to the putative Indo-Pacific Bryde's whale. [citation needed]. [14] The body mass of Bryde's whales can range 12–25 metric tons (13–28 short tons). Tamura, T., Konishi, K., Isoda, T. and P. Okamoto. At sexual maturity, males average 11.9 m (39 ft) and females 12 m (39 ft) near Japan. The head and the eyes are very large. The whales can weigh about 90,000 pounds and … Anderson, J. Despite terrible weather, he was able to secure almost the entire skull and nearly all its vertebrae, along with other bones. [11], Several differences in anatomy are seen between Bryde's and Eden's whales; morphological similarities have caused confusions regarding species identification.[12]. The Bryde’s Whale is found in tropical, subtropical and temperate waters across the central strip of the globe’s oceans. About the Whale They are deep divers, and are seldom seen in groups. An unknown number were also caught off Chile from 1932–79. According to recent research, Bryde’s whales like to spend most of their days hanging out within 50 feet of the water’s surface. Bryde's have a straight rostrum with three longitudinal ridges that extend from the blowholes, where the auxiliary ridges begin as depressions, to the tip of the rostrum. The common Bryde's whale (Balaenoptera brydei, Olsen, 1913) is a larger form that occurs worldwide in warm temperate and tropical waters, and the Sittang or Eden's whale (B. edeni, Anderson, 1879) is a smaller form that may be restricted to the Indo-Pacific. The coastal form near Japan is slightly smaller, with adult males averaging 12.9 m (42 ft) and adult females 13.3 m (44 ft). Weight:26,400 - 44,000 lbs (12 - 20 tons) Length:29.5 - 59 ft (9 - 15.5 m) Diet:Krill and small schooling fish. [34], B. brydei occurs throughout the Indian Ocean north of about 35°S. As baleen filter-feeders, they use multiple strategies for feeding, including bubble nets, skimming, and lunging. [5], The 40 to 70 ventral pleats extend to or past the umbilicus, occupying about 58% and 57% of the total length, respectively; sei whales, though, have ventral pleats that extend only halfway between the pectoral fins and umbilicus, occupying only 45–47% of the total body length, whereas their umbilicus is usually 52% of the total body length. Bryde's are dark smoky grey dorsally and usually white ventrally, whereas sei whales are often a galvanized blue-grey dorsally and have a variably sized white patch on the throat, a posteriorly oriented white anchor-shaped marking between the pectoral fins, and are blue-grey beyond the anus—although Bryde's off South Africa can have a similar irregular white patch on the throat. Bryde's whales are sexually mature at the age of 10 to 13 years. Five were west of San Clemente Island, and one between San Clemente Island and Santa Catalina Island. Bryde's Whale on The IUCN Red List site -, https://en.wikipedia.org/wiki/Bryde%27s_whale, http://www.iucnredlist.org/details/2476/0. Individuals living close to the shore may feed in groups of 15 or fewer, while those off-shore may be in groups that number up to 30. When diving for food, Bryde's whales can stay underwater for as long as 20 minutes before coming up for air. Bryde's whales are named after Johan Bryde, a Norwegian who built the first of the South Africa's whaling stations. The Bryde’s whale (pronounced “broo-dess”), is named after Johan Bryde who helped build the first whaling factory in Durban, South Africa in 1909. Scientists have been unable to find an explanation for such behavior. The recently described Omura's whale (B. omurai, Wada et al. It was realized that the northern form were indeed sei whales (B. borealis), but the southern form were Bryde's whale (B. As modern whaling shifted to the Sanriku area, whalemen confused the sei whale with it; now iwashi-kujira (鰯鯨, "anchovy whale" イワシクジラ) only applies to the latter. Full Title: Trophic Interactions and Habitat Requirements of Gulf of Mexico Bryde’s Whales This project will develop a comprehensive ecological understanding of Gulf of Mexico Bryde’s whales, including the physical, oceanographic, and biological features defining critical habitat and their ecological role in Gulf of Mexico marine food webs. One of the northernmost records in modern times was of a beached, 5-meter-long specimen at Nakhodka in 2011. The Bryde’s Whale has between 250 and 365 baleen plates in its ample jaws. [44], The type specimen is from the Gulf of Martaban coast of Myanmar, while other referred specimens were found on the Bay of Bengal coast of Myanmar, Bangladesh, India, Thailand to Vietnam, Taiwan and continental China. They appear to occur off Brazil year-round, such as around Rio de Janeiro—Cape Frio,[38] Armação dos Búzios, entrance to Guanabara Bay,[39][40][41][38] Ilha Anchieta State Park, Ilha Grande, and so on. On 29 January 2019, a 38-foot male Bryde’s whale stranded in the Florida’s Everglades. Yamada, T. K., L.-S. Chou, S. Chantrapornsyl, K. Adulyanukosol, S. K. Chakravarti, M. Oishi, S. Wada, C.-J. The whale gripped him with its jaws for a few moments as Schimpf held his breath and feared the whale would deep dive. At least some Bryde's whales were among the 5,000 sei whales recorded in the catch off Brazil from 1948–77, but possibly only 8%.[28]. [25][26], Bryde's whales breed in alternate years, apparently in any season, with an autumnal peak. [57] Another sighting was made off Dana Point, California, on 19 September 2009, which was originally misidentified as a fin whale.
