Description
The red lionfish is a striking scorpionfish (family Scorpaenidae) originally from the Indo-Pacific. The species grows to about 46 cm and has a red-and-white striped body with long, fan-like pectoral fins and a row of venomous spines on the back. It inhabits lagoon and seaward reefs, from turbid inshore areas to about 50 m depth, and is often solitary; by day it hangs almost motionless head-down in sheltered places, and at night it hunts small fishes and crustaceans. The spines can deliver a very painful, venomous sting. Outside its native range the species is notorious as an invasive intruder in the Atlantic.
