Classification / Names Noms communs | Synonymes | Catalog of Fishes(Genre, Espèce) | ITIS | CoL | WoRMS | Cloffa

Élasmobranches (requins et raies) (sharks and rays) > Lamniformes (Mackerel sharks) > Lamnidae (Mackerel sharks or white shark)
Etymology: Isurus: isos (Gr.), equal; oura (Gr.), tail, referring to caudal-fin lobes of I. oxyrinchus being equal in length (except that they are not; the upper is clearly longer). (See ETYFish);  paucus: Latin for scarce, referring to its relative rarity compared with I. oxyrinchus. (See ETYFish).

Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 0; Épines anales 0; Rayons mous anaux: 0. Pectoral fins about as long as head or longer, relatively broad-tipped in young and adults; snout usually narrowly to bluntly pointed, usually not acute; cusps of upper and lower anterior teeth straighter, with tips not reversed (Ref. 43278). Caudal fin lunate, with a very long lower lobe (Ref. 13574). Dark blue above, white below, with dusky markings on underside of snout, around mouth (Ref. 6581).

Biologie     Glossaire (ex. epibenthic)

Oceanic species that probably approaches land to give birth (Ref. 13574, 58302). Epipelagic (Ref. 58302). Presumably feeds on schooling fishes and pelagic cephalopods (Ref. 247). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). With 2 pups in a litter (Ref. 247). Potentially dangerous because of its large size and big teeth (Ref. 13574). Utilized fresh, frozen, and dried or salted for human consumption (Ref. 247); meat (lower quality), fins (high value in adults), jaws (highly prized), skin and cartilage (Ref.58048).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). With litters of 2-8 pups (Ref. 247, Ref.58048). Distinct pairing with embrace (Ref. 205). Born at 97-120 cm TL (Ref.58048).
