Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm SL male/unsexed; (Ref. 8991); common length : 35.0 cm SL male/unsexed; (Ref. 9645)
Found on outer reef slopes, hovering above the bottom. They swim often high above the substrate to pick prey from the substrate with their excellent eyesight (Ref. 48635). Tends to swim away from its pursuer rather than enter its burrow (Ref. 1602). Solitary or in pairs (Ref. 9710), adults form monogamous pairs (Ref. 37816). Maximum depth from Ref. 027115.
