Where seen? This fish with a flat head and a delicate fringe over its eyes is commonly seen on many of our shores, in sandy and coral rubble areas near reefs.

Features:
Those seen 6-20cm, but said to reach up to 58cm. Tiny ones about 2cm long have also been seen. Identified by the elaborate golden filigree fringe over the eyeball. Above the eyes 6-9 large fleshy tentacles. It has bony ridges on the head with spines. Colours and pattern are camouflaging, with 7-8 dusky bars on the back and sides and its fins has variegated patterns. Dorsal fin large and sometimes colourful.

Sometimes mistaken for other flattened fishes that live on the sea bottom. Here's more on how to tell apart fishes with flat heads.
