Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 47 - 52; Rayons mous anaux: 43 - 45; Vertèbres: 53 - 57. This species is distinguished from all its congeners described in North Pacific by having a small teardrop-shaped body, with loose thin skin, and anterior dorsal-fin rays buried in tissue; differs from C. spiraki and C. maslenikovae in lacking small, rounded bumps
on its body and in having a single chin pore (vs. two chin pores), higher counts of pectoral-fin rays 32-38 (vs. 28-32 in C. spiraki, 26-29 in C. maslenikovae), vertebrae 53-57 (vs. 42-46 and 42-43, respectively), dorsal-fin rays 47-52 (vs. 38-43 and 38-40), and anal-fin rays 43-45 (vs. 32-37 and 32-33) (Ref. 124469).
Cross section: compressed.
