Biologie     Verklarende woordenlijst (b.v. epibenthic)

Inhabits inshore silty reefs; there are no records from depths greater than 50 m. Feeds on shrimps, small fishes, worms and crabs (Ref. 89707). The enlarged fleshy pectoral fins appear to have resulted from its habit of sitting on the substrate. Solitary (Ref 90102).
