Biologia     Glossario (es. epibenthic)

A nocturnal and territorial species (Ref. 12382), commonly lurking in holes, and writhing snakelike through crevices, under rocks or corals. Feeds on fish, crabs and squid (Ref. 12382). It seldom attacks unless provoked (Ref. 3256). A gonochoristic species (Ref. 32169). Utilized fresh and eaten broiled, boiled and baked; the skin can be used for leather (Ref. 9987).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 13.1 - 16.2, mean 14.4 (based on 181 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00132 (0.00104 - 0.00167), b=3.08 (3.01 - 3.15), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
