FBname: Abyssal halosaur
Comments: Found on the lower slope, continental rise and upper abyss, primarily between 4° and 2°C isotherms.  Feeds on polychaetes, crustaceans, echinoderms and echiurids.  Hovers above or rests on bottom.  Long slender pectorals are commonly held erect pointing upward and forward, these may serve a sensory function (Ref. 6727).
