during this study from december 2009 to november 2011, 363deep flounder fish were caught and their weight and length were measured. the caught fish included 18 males, 200 females and 155 immature fishes. the mean, maximum and minimum total lengths were 264 ± 57 (mean ± sd), 415 mm and 115 mm respectively. the mean, maximum, and minimum total weights for this species were 238 ± 150 g, 827 g and ...

The Persian Gulf is of great economical, environmental and political importance, and includes around 205 species of fishes that only some of them have been studied parasitologically. From the order Pleuronectiformes ( ray-finned fishes), Psettodes erumei (Psettodidae), Pseudorhombus elevatus (Bothidae) and Brachirus orientalis (Soleidae) were selected for the survey. One hundred and forty eig...

Six species of the genus Picromerus Amyot and Serville from China were reported, in which, Picromerus elevatus sp. nov. from Yunnan province, was described as new to science. Drawings and photographs of genital characters, photographs of imagoes in dorsal and ventral views, and some diagnostic characters were provided, together with a detailed key to the six species occurring in China. The type...

Theridiidae is a derived family within the Araneoidea clade. In contrast to closely related groups, the 2n(male) = 20+X(1) X (2) with acro/telocentric chromosomes is the most widespread karyotype among the theridiid spiders. In this work, the cytogenetic analysis of Argyrodes elevatus revealed original chromosome features different from those previously registered for Theridiidae, including the...

Five new Chinese species of Cephennodes (s. str.) are described: C. bicavatus sp. n. (Guangdong), C. pseudobos sp. n. (Guangxi), C. huapingensis sp. n. (Guangxi), C. elevatus sp. n. (Guangxi), and C. gaozhaianus sp. n. (Guangxi). Cephennodes qiongdaoanus Jałoszyński and C. capricornis Jałoszyński are recorded for new localities in the provinces of Guangxi and Hainan, respectively. Diagnostic ch...

This study investigates predation by the vent zoarcid fish Thermarces cerberus through gastrointestinal analyses of 27 specimens collected with the submersible ALVIN at vents at 91500N on the East Pacific Rise. T. cerberus fed most frequently on gastropod mollusks (mainly Lepetodrilus elevatus) and amphipod crustaceans (mainly Ventiella sulfuris). Species found occasionally in high abundance in...
