Elasmobranchii (Haie und Rochen) (sharks and rays) > Lamniformes (Mackerel sharks) > Odontaspididae (Sand tiger sharks)
Etymology: Odontaspis: Etymology not explained, presumably odontos (Gr.), tooth, and aspis (Gr.), shield, perhaps referring to how teeth comprise a prominent narrow cusp provided with two or more small “side teeth” (translation), i.e., cusplets, which, with some imagination, could be said to “shield” the main cusp; another explanation: aspis (L.), viper, perhaps referring to outwardly pointing teeth of O. ferox, like that of a viper. (See ETYFish); noronhai: In honor of Adolfo César de Noronha (1873-1963), late director of the Funchal Museum (Madeira), where holotype is housed. (See ETYFish).

Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Snout conical and bulbous, tip rounded. Eyes large and ovoid, nictitating membrane absent. Body color uniform chocolate brown, all fins except pectorals with thin dark edging along posterior margin.

A deepwater shark inhabiting the continental and insular slopes (Ref. 50449, 58302). Pelagic (Ref. 58302). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Feeding habits unknown.

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 8.6 - 15.2, mean 12 °C (based on 13 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Preiskategorie (Ref. 80766): Unknown.
