Silver Pearlfish

This pearlfish inhabits the coelom and respiratory trees of some holothurians, especially @Stichopus chloronotus@ and @Holothuria argus@. It is apparently in competition with @Jordanicus gracilis@ for its preferred host @H. argus@. Although most occur singly, there is a tendency towards sexual pairing inside the host. Stomach contents which include amphipod, shrimp and fish indicate non-parasitic, foraging habits (Ref. 6395).
