Distribution |
Known in Australia from off Geraldton to the North West Cape, Western Australia, and from north Queensland to off Port Stephens, New South Wales. Elsewhere, circumglobal in tropical and warm-temperate oceanic waters. |
|
Biology |
Little is known of the biology of this species. It is aplacental viviparous (ovoviviparous) with oophagy and uterine cannibalism. Once the largest embryos have used up their yolk sac, they feed on their smaller siblings and unfertilised eggs produced by the mother. Females give birth to two pups per litter. |
|
Fisheries |
Taken as bycatch in tropical pelagic longline tuna, swordfish and shark fisheries. Also taken in hook and line fisheries and caught in anchored gillnets. The species is usually finned and discarded at sea rather than being landed. |
|
Conservation |
IUCN REd List of Threatened Species: Vulnerable. In Australia, the Longfin Mako has been identified as a conservation value species in the South-west and Temperate East marine regions. |
