簡短描述
檢索表 | 型態特徵 | 形態測量圖
脊椎骨: 43 - 44. This species is diagnosed from its congeners by the total infraorbital pores 11-13, infraorbital 1 pores five to six (vs. 13-14, rarely 11, infraorbital 1 pores seven to eight); lower jaw short, not extending beyond upper jaw, 63.9-72.7% HL (vs. elongated lower jaw, extending beyond upper jaw, 73.3-77.1% HL in C. asper; 76.0-83.8% HL in C. braueri, 80.8-89.9% HL in C. harteli, 76.8-85.2% HL in C. microcephalus, 72.2-80.0% HL in C. niger, and 72.2-77.0% HL in C. pluriradiatus). It further differs from other species by the blunt snout, and short 21.4-23.9% HL (vs. elongated and pointed 23.0-26.6% HL in C. harteli; 23.7-28.0% HL in C. microcephalus; 22.2-26.6% HL in C. niger); upper jaw 63.9-72.7% HL (vs. 70.0-77.1% HL in C. braueri; 74.3-84.2% HL in C. harteli; and 72.2-80.0% HL in C. niger); from C. braueri, by the absence of teeth on second ceratobranchial (vs. present); from C. harteli by the total vertebrae 43-44 (vs. 47-48), and supraorbital pores 7-8 (vs. six, rarely 7); from C. pluriradiatus and C. asper, by pectoral-fin rays 12-13 (vs. 15-16), no tiny dermal spinules on body in specimens larger than 48.7 mm (vs. spinules present), and fang on premaxillary head 1 (vs. 2) (Ref. 82429).
Found in the mesopelagic to bathypelagic zones (Ref. 82429).
