Classification / Names Noms communs | Synonymes | Catalog of Fishes(Genre, Espèce) | ITIS | CoL | WoRMS | Cloffa

Élasmobranches (requins et raies) (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Halaelurus: halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish); boesemani: In honor of Marinus Boeseman (1916-2006), curator of fishes at the Rijksmuseum van Natuurlijke Historie (Leiden, Netherlands), for his “important” contributions to ichthyology. (See ETYFish).

Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0; Épines anales: 0. Dark spots small and very numerous, usually not larger than spiracles, over or between weak saddles or bars (Ref. 11146).

A little-known but wide-ranging bottom-dwelling shark found on continental and insular shelves (Ref. 11146). Probably caught with bottom trawls (Ref. 30573). Live-bearing (Ref. 50449).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Up to 4 egg capsules may be found in an oviduct but it is uncertain whether these hatch inside the oviduct or if the eggs are laid (Ref. 244). Live-bearing (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 19.6 - 27.9, mean 25 (based on 441 cells).

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

Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.3 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).

Catégorie de prix (Ref. 80766): Low.
