Etymology:
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; demersal; non-migratory; depth range 1 - 150 m (Ref.
34024
). Subtropical; 42°N - 15°S
Eastern Atlantic: including the Mediterranean. Probably south to Ascension Island.

Maturity: L

?
  range ? - ? cm
Max length : 20.8 cm TL male/unsexed; (Ref.
6347
)
Dorsal
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
).
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
).
