Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Parmaturus: parma (L.), from parme (Gr.), small shield; oura (Gr.), tail, presumably referring to upper edge of caudal fin “armed with modified” scales (per Garman 1913). ( See ETYFish ) ;   xaniurus: xanion (Gr.), comb for carding wool; oura (Gr.), tail, referring to crest-like row of tooth-like projections along upper edge of caudal fin. ( See ETYFish ) .

Biology     Glossary (e.g. epibenthic)

Found on the outer continental shelf and upper slope. Feeds on a variety of small fish (e.g. lanternfish) and invertebrates. Oviparous. Possesses an enlarged gill region which is an adaptation to areas with low dissolved oxygen levels. Has a high concentration of squalene in its liver which affords it neutral buoyancy. Regularly caught by bottom trawlers but not utilized at all.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 6 - 14.9, mean 7.9 °C (based on 29 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00282 (0.00160 - 0.00498), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.8   ±0.0 se; based on diet studies. Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Fishing Vulnerability (Ref. 59153 ):  Moderate vulnerability (42 of 100).
