Comments: Found on shelf waters of islands and caught in 2 bottom trawls at depths of 126 and 270-310 m, together with <i>C. rhinoceratus</i>, <i>C. rugosus</i>, <i>C. panticapaei</i>, <i>C. bospori</i>, <i> C. irinae</i> and <i>C. mithridatis</i>.  Most specimens were caught at depth of 126 m in an area with abundant benthic fauna and the alga <i>Macrocystis pyrifera</i>.  Apparently a primarily piscivorous predator (inferred from the single row of gill-rakers and similar to its congeners).  Females mature at about 29-31 cm TL (25-27 cm SL); the post-spawning SGM VI-III is clearly detected in females larger than 31 cm TL and the SGM III - in the smaller, firstly maturing ones.  The SGM of the males examined varied from stage II to early stage III in the specimen of 32.5 cm TL.  Spawning and pre-spawning SGM were absent.  Spawning period apparently takes a place from autumn to the beginning of winter (Ref. 90862).
