Sliteye Shark, Loxodon macrorhinus Müller & Henle 1839

More Info


Distribution

Known in Australian waters from Geraldton, Western Australia, to about Moreton Bay, Queensland. Elsewhere, the species is widespread in the Indo-West Pacific from South Africa to southern Japan and northern Australia. 

Feeding

Feed on bony fishes, crustaceans and cephalopods.

Biology

Females reproduce annually, with litters of two pups born at a length of 40-45 cm. The Sliteye Shark is relatively fast growing and matures early at 60 cm TL - in contrast to large-bodied carcharhinid shark which grow relatively slowly and are late to mature.

Fisheries

Although rarely targeted, Sliteye Sharks are commonly taken in artisanal, subsistence and commercial fisheries throughout their range.
