Etymology: Encheliophis: Greek, enchelys, = eel + Greek, ophis = serpent (Ref. 45335).
Eponymy: Sir Everard Home (1756–1832) was an English physician and naturalist, and an early wombat owner (in the early 19th century it was very fashionable to own exotic pets from Australia). [...] (Ref. 128868), visit book page.

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).
Body shape (shape guide): eel-like; Cross section: oval.
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).
