<P> The frilled shark ( Chlamydoselachus anguineus ) is one of two extant species of shark in the family Chlamydoselachidae , with a wide but patchy distribution in the Atlantic and Pacific Oceans . This species is found over the outer continental shelf and upper continental slope , generally near the bottom , though there is evidence of substantial upward movements . It has been caught as deep as 1,570 m ( 5,150 ft ) , although it is uncommon below 1,200 m ( 3,900 ft ) . In Suruga Bay , Japan , it is most common at depths of 50 -- 200 m ( 160 -- 660 ft ) . Exhibiting several primitive features , the frilled shark has often been termed a living fossil . It reaches a length of 2 m ( 6.6 ft ) and has a dark brown , eel - like body with the dorsal , pelvic , and anal fins placed far back . Its common name comes from the frilly or fringed appearance of its six pairs of gill slits , with the first pair meeting across the throat . </P>
