Biologie     Glossaire (ex. epibenthic)

Found in tide pools and reef crevices. Also found in sheltered inner reefs, usually in caves with sponges and below large plate corals. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Very active cleaner and has cleaning station that is visited by apogonids and damsels where adults work in pairs (Ref. 48635). Minimum depth from Ref. 58018. Solitary or in pairs (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 115969): 25.9 - 29.3, mean 28.7 (based on 2406 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00085 (0.00032 - 0.00224), b=3.04 (2.81 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.9   ±0.5 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
