Short description

Dorsal soft rays (total): 33-38; Anal soft rays: 53 - 61; Vertebrae: 116 - 128. Eel-like, moderate to shallow body depth; maxilla free and movable; cardiform teeth present; branchiostegal membranes partly or completely united; swim bladder with thin terminal membrane or bulb; lacking enlarged dentary or premaxillary fangs, dentary diastema, pelvic fins, and swim bladder rocker bone (Ref. 34024).

This uncommon (Ref. 34024) pearlfish inhabits the coelom and respiratory trees of some holothurians, especially Stichopus chloronotus and Holothuria argus. It is apparently in competition with Jordanicus gracilis [= Encheliophis gracilis] for its preferred host H. argus. 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).
