The first dorsal spine, the illicium is modified and is used as a fishing rod.

The pectoral fins are angled and help, with the pelvic fins, to move the fish on the bottom and to keep a stable position for ambush predation.

Length up to 15 cm (6 inches).

DISTRIBUTION/HABITAT: Indian and Western Pacific Oceans among sheltered rocky reefs, algae, sponges and soft corals to 15 meters (49 feet).  It is a reef dweller, perching on coral ledges.
