Descrição breve Chaves de identificação | Morfologia | Morfometria

Vértebras: 43 - 44. This species is distinguished from its congeners by a set of characteristics: from C. braueri by the teeth on second ceratobranchial absent (vs. present) and supraorbital canal pores 7 (vs. 8); from C. harteli by total vertebrae 43-45 (vs. 47-48), supraorbital canal pores 7 (vs. six); from C. microcephalus by teeth on basibranchials well developed, 3-18, always present on second basibranchial and often on third basibranchial and second hypobranchial (vs. usually no teeth on basibranchials, rarely 1-3, small, restricted to second basibranchial); from C. pluriradiatus and C. asper, by pectoral-fin rays 13-14 (vs. 15-16), tiny dermal spinules on body of specimens larger than 45.0 mm absent (vs. with spinules), fang in premaxillary head 1 (vs. 2), and supraorbital pores 7 (vs. 8 and 9, respectively) and from C. pluriradiatus by lateral-line pores 86-93 (vs. 91-94); from C. subniger, by teeth on second basibranchial present (vs. none), infraorbital pores 14 (vs. 12-13, modally 13), snout elongate and pointed, 22.2-26.6% HL (vs. snout short and blunt, 21.4-23.9% HL), upper jaw 72.2-80.0% HL (vs. 63.9-72.7% HL), and lower jaw 80.0-86.7% HL (vs. 69.0-76.7% HL) (Ref. 82429).

Mesopelagic to bathypelagic species (Ref. 6944, 28429). Specimens larger than 4.5 cm are more frequently collected between 730 and 1900 m with shallowest record being 150 m, the deepest 3900 m (mean 1390 m). Juveniles are found in shallower water, from 0 to 1,050 m (mean 542 m), with the smallest specimens (>10.0 mm) collected nearest to the surface (Ref. 82429). Feed on whole fish, often of individuals longer than themselves (Ref. 9686). Most specimens were taken at depths greater than 750 m (Ref. 6649).

Estimates based on models

Preferred temperature (Ref. 115969): 4.2 - 8.7, mean 4.9 (based on 355 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.2 ±0.73 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
