Elasmobranchi (squali e razze) (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Bythaelurus: bythos (Gr.), depths of the sea, referring to its deepwater habitat; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes (See ETYFish); lutarius: Latin for “of the mud,” referring to its habitat on or just above muddy bottoms at 338-766 m (See ETYFish).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0. A slender, dwarf catshark with a moderately long snout and short labial furrows; caudal fin without crest of enlarged denticles (Ref. 5578). Dull grey-brown, paler ventrally, with few poorly defined dorsal saddles that may be visible (Ref. 5510).

Found on the continental slope on or just above muddy substrates (Ref. 5578). Feeds on cephalopods, small bony fishes, and crustaceans (Ref. 5578). Probably caught with bottom trawls (Ref. 30573).

Estimates based on models

Preferred temperature (Ref. 123201): 9.4 - 12.4, mean 11.4 °C (based on 17 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.56 se; based on food items.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=2).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).
