Description

The frilled shark is an eel-shaped primitive shark of the family Chlamydoselachidae reaching about 2 metres, often called a 'living fossil'. The slender, dark-brown body has six pairs of gill slits with frilly edges, dorsal, pelvic and anal fins set far back, and a terminal mouth full of hundreds of three-pronged, needle-sharp teeth. The species occurs worldwide but is everywhere rare, along continental slopes in the deep sea, including the eastern Atlantic, usually at hundreds to over a thousand metres. With its expandable mouth and jaws it seizes squid, other sharks and fish, which it can swallow whole. Reproduction is ovoviviparous with an exceptionally long gestation. Living specimens are only rarely observed.
