Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 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).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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).

Life cycle and mating behavior Maturities | Fortpflanzung | Spawnings | Egg(s) | Fecundities | Larven

It is not yet established whether spawning is seasonal or sporadic in carapids. Eggs elliptical and planktonic (Ref. 6355).

Estimates based on models

Preferred temperature (Ref. 115969): 14.8 - 27.6, mean 19.4 (based on 324 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 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):  4.0   ±0.63 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
