Biology     Glossary (e.g. epibenthic)

Occurs in lagoons or bays, in passes, or on outer reef slopes; over hard substrate as well as patches of rubble or sand, usually at the base of the reef. Adults are usually in pairs and share burrow which is often under a piece of rubble or slab of coral rock. Adults feed on current-borne zooplankton as high as 3 m above the burrow; tend to remain together while feeding, separated by not more than 1-2 m. Monogamous (Ref. 52884, 48637). Juveniles occur in large groups, as many as 500. Minimum depth reported from Ref. 27115.

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 29.2, mean 28.1 °C (based on 2894 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
