Where seen? This small scorpionfish wannabe is commonly encountered on some of our shores, among coral rubble and seagrass areas.

What are false scorpionfishes? This species was previously placed in Family Serranidae (groupers) and now is the only member of the Family Centrogenyidae (false scorpionfishes). True scorpionfishes belong to the Family Scorpaenidae.

Features:
To about 15cm, but those seen usually about 4-10cm. Like scorpionfishes, the false scorpionfish has prickly dorsal spines that can poke inquisitive fingers. But false scorpionfishes lack true venom glands and simply cause wounds. Unlike scorpionfishes, the false scorpionfish does not have spines on its head. The nostrils have large fringed flaps, and the dorsal fin starts well behind the eyes. But in other respects, they are similar in habit and appearance.


Sometimes mistaken for stonefishes and scorpionfishes. Here's more on how to tell apart fishes that look like stones.


What does it eat? It eats small fishes, shrimps and crabs, hunting during the day.

Human uses: Sometimes harvested for the aquarium trade.
