The Bigeye Thresher (Alopias superciliosus) is a thresher shark of the genus Alopias, found in tropical oceans worldwide, at depths down to 500 metres. Its length is up to 5 metres, and weight to 360 kilogrammes.
The Bigeye Thresher is a large shark, with very large eyes indicating time spent at unlit depths. It has an indented forehead and large broad pectoral fins, and the first dorsal fin set further back than that of other thresher sharks. The upper caudal lobe is very long and strap-like, virtually the same length as the body.
The colour is purplish grey above, bream below, with posterior edges of pectoral and pelvic fins dusky.
Bigeye Threshers are found in all types of water; coastal shallows, over the continental shelf, and at sea far from land, at all depths down to 500 metres.
