Etymology: Alopias: Greek, alopex = fox (Ref. 45335 ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; pelagic-oceanic; oceanodromous (Ref. 51243 ); depth range 0 - 300 m (Ref. 106604 ), usually 0 - 150 m (Ref. 55167 ).   Tropical; 40°N - 42°S, 16°E - 70°W (Ref. 54277 )

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Circumglobal. Indo-Pacific: Red Sea, Arabian Sea, Maldives (Ref. 30829 ), Somalia, South Africa, Western Australia, China, Taiwan, Japan, New Caledonia, Hawaiian Islands and Tahiti. Eastern Pacific: Gulf of California and the Galapagos. Reliable records lacking partly due to its confusion with Alopias vulpinus .

Length at first maturity / Size / Weight / Age

Maturity: L m   ? , range 260 - 292 cm
Max length : 428 cm TL male/unsexed; (Ref. 106604 ); 383.0 cm TL (female); common length : 276 cm TL male/unsexed; (Ref. ); max. reported age: 29 years (Ref. 48844 )

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 0. A small thresher with moderately large eyes, a broadly convex forehead, a very narrow caudal tip, and straight, broad-tipped pectoral fins (Ref. 5578 ). Upper lobe of caudal fin very long and strap-like, almost equal to length of rest of shark; lower lobe short but strong; terminal lobe very small (Ref. 13570 ). Dark blue on back and sides, underside white; no white patch over pectoral fin bases (Ref. 5578 ).

Biology     Glossary (e.g. epibenthic)

Primarily an oceanic species but sometimes close inshore (Ref. 247 , 5578 , 58302 ); neritic to oceanic, 0-152 m (Ref. 11230 ). Epipelagic (Ref. 58302 ). Mesopelagic in the tropics; may enter atoll lagoons (Ref. 37816 ). Stuns its prey with its tail, presumably feeding on small fishes and cephalopods (Ref. 6871 ). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 43278 , 50449 ). Sometimes caught by ski-boat anglers (Ref. 5578 ). Utilized for human consumption, liver oil for vitamin extraction, hides for leather, and fins for shark-fin soup (Ref. 13570 ). A very common catch in the tuna and shark longline, and tuna drift net fisheries (Ref.58048). Maximum and common size of males estimated from discussion in Ref. 247. Adult females may reach at least 330 cm TL (Ref. 47613 ).
