Description
The Hawaiian lionfish is a lionfish (Scorpaenidae) endemic to the waters around Hawaii. The species grows to about 22 cm and has a red-brown banded body with long, fan-shaped pectoral fins and tall, needle-like dorsal spines. The dorsal, pelvic and anal spines are linked to powerful venom glands; a sting is very painful.
