FBname: Silver pearlfish
Comments: This uncommon (Ref. 34024) pearlfish inhabits the coelom and respiratory trees of some holothurians, especially <i>Stichopus chloronotus</i> and <i>Holothuria argus</i>.  It is apparently in competition with <i>Jordanicus gracilis</i> [= <i>Encheliophis gracilis</i>] for its preferred host <i>H. argus</i>.  Although most occur singly, there is a tendency towards sexual pairing inside the host.  Found to depths over 30 m (Ref. 9710).  Stomach contents which include amphipod, shrimp and fish indicate non-parasitic, foraging habits (Ref. 6395). Leaves host at night to prey on small fishes and shrimps (Ref 90102).
