Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 6 - 8; Afterflossenweichstrahlen: 5 - 6. Distinguishing characteristics of metamorphosed female: esca with a pair of elongate internally pigmented and bilaterally placed anterior appendages, less than one-tenth to greater than length of escal bulb; smaller ratio between number of upper and lower jaw teeth, 0.70-0.94; total number of teeth in upper jaw teeth 28-40, lower jaw 34-57 teeth; vomerine teeth 4-8; length of illicium 22.4-40.3% SL; escal bulb width 5.3-11.4% SL; has fewer dorsal and anal fin rays than C.ramifera, and greater number of pectoral fin rays than all other species of the genus (Ref. 86949).
Body shape (shape guide): short and / or deep.
Bathypelagic (Ref. 58426). Also mesopelagic. Males dwarfed, non-parasitic (Ref. 10524). Feeds on fishes, cephalopods and crustaceans (Ref. 58426).
