Short description Morphology | Morphometrics

Dorsal soft rays (total): 35-41; Anal soft rays : 54 - 61; Vertebrae : 102 - 114. Eel-like, moderate to shallow body depth; cardiform teeth present but restricted to upper jaw symphysis; swim bladder constricted (under vertebrae 9 or 10) forming two chambers; lacking enlarged dentary or premaxillary fangs, dentary diastema, pelvic fins and swim bladder rockerbone (Ref. 34024 ). Differs from Encheliophis homei by possessing scattered melanophores over most of the body (Ref. 37816 ).

Biology     Glossary (e.g. epibenthic)

Common species (Ref. 34024 ). Found in starfishes (mainly) and holothurians (Ref. 4104 ), usually in a male - female pair (Ref. 11228 ). Benthic (Ref. 58302 ). In Micronesia, it prefers the pincushion starfish Culcita novaeguinae for a host. Also known to occur in certain holothurians ( Bohadschia argus , Stichopus sp.) on rare occasions (Ref. 1602 ); for the first time with Isostichopus fuscus along the coast of Ecuador (Ref. 57700 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 23.6 - 28.9, mean 27.6 °C (based on 1346 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.6   ±0.5 se; based on size and trophs of closest relatives Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (11 of 100).
