Ikan bertulang rawan (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus). (See ETYFish);  riveri: In honor of biologist-anthropologist Luis Hugo Howell-Rivero (1899-1986), for his contributions to Cuban ichthyology (this shark described from the north coast of Cuba). (See ETYFish).

deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

Relatively slender, moderately long, narrow snout and relatively narrow, low caudal fin. Color uniform dark brown (Ref. 37039). First to third gill openings long as the distance between the nostrils (Ref. 6032).

Biologi     Daftar kata (contoh epibenthic)

Found on the continental slopes. Oviparous, with one egg per oviduct laid at a time. Sexual dimorphism in adults unusually well-developed.

Life cycle and mating behavior Maturities | Reproduksi, perkembang biakan | Spawnings | Egg(s) | Fecundities | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Sexual dimorphism is evident in dentition of males (Ref. 49562). Males have longer teeth with fewer cusps (Ref. 51093) to make 'courtship biting' more effective (Ref. 49562).

Estimates based on models

Preferred temperature (Ref. 123201): 4.9 - 7.9, mean 5.7 °C (based on 95 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [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).
Trophic level (Ref. 69278):  3.8   ±0.4 se; based on size and trophs of closest relatives
Daya lenting (Ref. 120179):  sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100).
