Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 6 - 8; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

Bathypelagic (Ref. 58426). Also mesopelagic. Males dwarfed, non-parasitic (Ref. 10524). Feeds on fishes, cephalopods and crustaceans (Ref. 58426).

Estimates based on models

Preferred temperature (Ref. 123201): 1.9 - 8.5, mean 6.6 °C (based on 226 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.55 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
