Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors. (See ETYFish); homonycteris: homo-, from hominis (L.), man; nykteris (Gr.), bat, referring to Thomas A. Griffiths, bat systematist known as “bat man,” who introduced Didier to chimaeroid fishes. (See ETYFish).

Descrição breve Chaves de identificação | Morfologia | Morfometria

This chimaeroid fish has a ventral caudal fin that that is not indented at its origin to form a separate anal fin, it is distinguished from its congeners by the following characters: color of the body an even dark black or blackish-brown; its dorsal fin spine is longer than height of first dorsal fin; pelvic fins is distinctly round in shape; males with pelvic claspers that are dark at the base with pale tips, divided for the distal 1/3 of their length (Ref. 76967).

Estimates based on models

Preferred temperature (Ref. 115969): 2.2 - 5.7, mean 4.6 (based on 177 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00275 (0.00138 - 0.00549), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (65 of 100).
