FBname: Largetooth cookiecutter shark
Comments: A very rare species known only from few localities in epipelagic waters. Apparently feeds on small epibenthic and epipelagic invertebrates and fish.  Its powerful jaws, big mouth and enormous lower teeth enable it to bite off large portion of its prey in one sweeping motion.  A facultative ectoparasite evidenced by its suctorial lips and feeding apparatus.  It has extremely short snout and anteriorly positioned eyes which allows for binocular vision (Ref. 247).  Caught by mid-water trawl (Ref. 55584).  Ovoviviparous (Ref. 205).  Has large oily liver which helps it to become neutrally buoyant (`hepatic float').
