होलोसैफली (किमाइरस) (chimaeras) > Chimaeriformes (Chimaeras) > Chimaeridae (Shortnose chimaeras or ratfishes)
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);  erithacus: Erithacus, avian genus of the robin, named after Robin Leslie, South African Department of Agriculture, Forestry and Fisheries, a “fanatic birder,” for his help and support with the authors’ project and his overall contribution to Chondrichthyan re (See ETYFish).

Short description आकृति विज्ञान | मौरफोमैटरिक्स

This species is distinguished from its congeners by the following set of characters: bulky and relatively large head is followed by a stocky body; head and body height consistent from about pectoral fin origins to pelvic fin origins, until the insertion of the pelvic fins, tapering rapidly to filamentous tail; height of first dorsal fin spine about equal to or slightly less than first dorsal fin apex height; second dorsal fin up to 81% of total body length, uniform in height, and equal to dorsal caudal fin height; paired claspers trifurcate, forked for approximately 20% of total length with fleshy, bulbous tips; prepelvic tenaculae with 5-7 medial spines; robust frontal tenaculum, nearly uniform in width; color when preserved uniform black with no distinct markings (Ref. 116866).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

This species is likely to occur beyond 2,000 meters. Fragments of possible crab appendages recovered from a digestive tract indicate a diet of crustaceans and other benthic fauna (Ref. 116866).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00118 - 0.00673), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179):  बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (87 of 100).
