Biologie     Glossaire (ex. epibenthic)

Occasionally encountered in shallower water in caves or at the bases of overhangs (Ref. 5288). Also occurs on seamounts (Ref. 057925). Usually occur in pairs, which browse over the rocky substratum in search of benthic invertebrates. Unknown to marine aquarium enthusiasts (Ref. 4858). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01117 - 0.04486), b=3.02 (2.85 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.5   ±0.37 se; based on food items.
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).
