Elasmobranchi (squali e razze) (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); ferox: Latin for fierce, possibly referring to what Risso described as its “La voracité extrême” and/or its toothy and ferocious countenance. (See ETYFish).

Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0. A shark with a short, pointed snout, small eyes, protruding spike-like teeth, and small, equal-sized dorsal and anal fins; first dorsal closer to pectoral than to pelvic fins (Ref. 5578). Grey above, paler below (Ref. 6586); may have red spots on sides (Ref. 5578).

Found on or near the bottom of the continental and insular shelves and upper slopes (Ref. 6871); sometimes in shallow water (Ref. 6871). Tagging showed the species dives up to 2,000 m at Malpelo Island, Colombia (S.Bessudo, pers.comm. 06/09). Feeds on small bony fishes, squids, and crustaceans (Ref. 13568). Uses its long body cavity and large, oily liver to regulate buoyancy. Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Not implicated in attacks on people (Ref. 247). Flesh utilized for human consumption and liver for its high squalene content (Ref. 247); utilization of fins, jaws and cartilage (Ref.58048).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). Two young born at 105 cm or larger (Ref. 26346). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 12.2 - 23.9, mean 17.3 (based on 810 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): 4.2 ±0.56 se; based on food items.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec assumed to be <10).

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

Price category (Ref. 80766): Unknown.
