soft rays
(total): 37-39. Eel-like, moderate to shallow body depth; cardiform teeth present but restricted to upper jaw symphysis; swim bladder constricted forming two chambers; lacking enlarged dentary or premaxillary fangs, dentary diastema, pelvic fins and swim bladder rockerbone (Ref. 34024). Possesses a free, movable maxilla (Ref. 6347).
Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
Eastern Atlantic: including the Mediterranean. Probably south to Ascension Island.
Common species (Ref. 34024). Adults typically live as commensals in the gut of shallow-water holothurians, Holothuria tubulosa and Stichopus regalis (although some deep-water records exist, see Ref. 6347). Prejuveniles (tenuis larvae) probably inhabit the same host species while the vexillifer and egg-rafts are planktonic. The fish may partly protrude or entirely leave its host at night to feed on small fish and benthic invertebrates. Reproduction noted in July-September. (Ref. 4741).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (-0.17398 - 0.17602), b=3.06 (2.97 - 3.15), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278): 4.0 ±0.63 se; Based on food items.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low vulnerability (11 of 100) .
