The seasonal growth pattern and reproductive biology of the rock pool prawn, Palaemon elegans, were studied in the southern Black Sea between February 2002 and January 2004. 3, pp. 25.1). Cuttlefish or cuttles are marine molluscs of the order Sepiida.They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses.Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy.. Cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. In the present study, genetic diversity and population structure … reproduction between Palaemon adspersus and Palaemon squilla (Berglund, 1980, 1981, 1982, 1984, 1985).

The size is variable, the average being 15 to 20 cm. In this species one-year-old females may either reproduce or postpone reproduction until the age of two years. In regard to the literature, this result raises questions concerning the kinetics of expression of genotoxic damage on progeny in the Palaemon model and future work will be led in this way. The organs are: 1. Palaemon Malcolmsonii: Excretory Organ # 1.
