Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Occurs at reef flats and outer reef slopes to a depth of at least 20 m. Feeds on fishes, cephalopodes and crustaceans (Ref. 89972). Unlikely to be encountered without the use of ichthyocide (Ref. 1602, 37816, 58302). Benthic (Ref. 58302). Possibly a protogynous hermaphrodite (Ref. 32169). Common, but highly cryptic and seldom seen (Ref 90102). Minimum depth reported taken from Ref. 86942.
