Any of the numerous species of carnivorous marine fish of the family Scorpaenidae, especially those in the genus Scorpaena, widely distributed in temperate and tropical waters. They have large, spiny heads and strong, sometimes venomous, fin spines. Many species blend with their surroundings by virtue of their dull colour, but some are brightly coloured, often red. The largest species grow to about 40 in. (1 m) long. Scorpion fish lie quietly on the bottom, often among rocks. See also lionfish; redfish; rockfish; zebra fish.
