The bigeye thresher, Alopias superciliosus, is a thresher shark of the genus Alopias, found in tropical oceans worldwide, at depths down to 500 m. Its length is up to 5 m (more typically 3 to 4 m), and weight up to 360 kg (more typically 160 kg). Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

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. Fish anatomy is primarily governed by the physical characteristics of water, which is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs light more than does air. ...
