Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 25 - 36; Anal soft rays: 42 - 52; Vertebrae: 136 - 140. Eel-like, moderate to shallow body depth; maxilla adnate or nearly so; 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). Swim bladder long, tubular, extending well beyond 12th vertebra (Ref. 34024).

Biology     Glossary (e.g. epibenthic)

Uncommon species (Ref. 34024). Benthic (Ref. 58302, 75154). Lives in starfish (Culcita discoidea) and sea cucumbers (Holothuria scabra and H. argus). In the latter reported by Trott (1970) to form male - female pairs and to parasite host. Parasitic, feeding on gonads and respiratory tree of its host. Usually associated with Bohadschia argus (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 24.4 - 28.8, mean 27.5 °C (based on 776 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [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):  3.0   ±0.00 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100).
Nutrients (Ref. 124155):  Calcium = 62.7 [34.4, 99.2] mg/100g; Iron = 0.613 [0.371, 1.118] mg/100g; Protein = 17 [14, 19] %; Omega3 = 0.102 [0.059, 0.172] g/100g; Selenium = 41.2 [21.5, 83.1] μg/100g; VitaminA = 82.8 [27.2, 245.1] μg/100g; Zinc = 1.59 [1.12, 2.16] mg/100g (wet weight);
