Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. A large, spindle-shaped shark with large black eyes, a sharp snout, and large, narrow, hooked teeth with smooth edges (Ref. 5578). Caudal fin lunate, lower lobe strongly developed (Ref. 13574). Dark blue above, white below (Ref. 6581). Tiny second dorsal and anal fins (Ref. 26938).

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

Cosmopolitan in temperate and tropical seas (Ref. 6871, 11230). Western Atlantic: Gulf of Maine to southern Brazil and Argentina (Ref. 58839), including the Gulf of Mexico and Caribbean. Eastern Atlantic: Norway to South Africa, including the Mediterranean. Indo-Pacific: East Africa to Hawaii, north to Primorskiy Kray (Russian Federation), south to Australia and New Zealand. Eastern Pacific: south of Aleutian Islands and from southern California, USA to Chile.

Biology     Glossary (e.g. epibenthic)

Oceanic, but sometimes found close inshore (Ref. 6871, 11230, 58302). Usually in surface waters (Ref. 30573), down to about 150 m (Ref. 26938, 11230). Coastal, epipelagic at 1->500 m (Ref. 58302). Isotope analysis has shown that shortfin mako is the highest level fish predator in oceanic waters off eastern Australia (Ref. 86961). Adults feed on bony fishes, other sharks (Ref. 5578), cephalopods; larger individuals may feed on larger prey such as billfish and small cetaceans (Ref. 6871, 58048). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 43278, 50449). With 4-16 young of about 60-70 cm long (Ref. 35388, 26346). Gestation period lasts 15-18 months, spawning cycle is every 3 years. Some authors (Refs. 1661, 28081, 31395) have erroneously assumed that two age rings are deposited per year by this species, thus underestimating longevity, age at maturity, and resilience . These data have been removed and replaced by recent, verified estimates (Refs. 86586, 86587, 86588). Tagging in New Zealand indicates seasonal migrations (Ref. 26346). The presence of genetic differentiation in mitochondrial DNA across global populations (Ref. 36416) suggests dispersal may be male-biased, and that females may have natal site-fidelity. Shortfin mako has been shown to have a marked sexually segregated population structure (Ref. 86954). Shortfin mako is probably the fastest of all sharks and can leap out of the water when hooked (Ref. 6871). Potentially dangerous and responsible for unprovoked attacks on swimmers and boats (Ref. 13574). Utilized fresh, dried or salted, smoked and frozen; eaten broiled and baked (Ref. 9988). Valued for its fine quality meat as well as its fins and skin (Ref. 247). Oil is extracted for vitamins and fins for shark-fin soup (Ref. 13574). Jaws and teeth are also sold as ornaments and trophies (Ref. 9988).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). With up to 18 young in a litter (Ref. 26346). Gives birth to litters of 4-25 (usually 10-18) pups after a gestation period of 15-18 months; reproduces every 3 years (Ref.58048). Size at birth between 60 and 70 cm (Ref. 247). Distinct pairing with embrace (Ref. 205).
