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).
这个稀有的 (参考文献 34024) 珍珠鱼居住于一些海参的体腔与呼吸树, 尤其 Stichopus chloronotus 与 Holothuria argus. 显然地它是在与 Jordanicus gracilis 竞争 [= 纤细隐鱼［Encheliophis gracilis］ ] 作为它喜欢的寄主 H. argus. 虽然大部分各别地出现, 但是，哪里是一趋向性的成对在寄主体内。 发现到深度超过 30 公尺。 (参考文献 9710) 包括片脚类动物，虾与鱼的胃内含物指出被觅食习惯的非寄生。 (参考文献 6395)
