Pterois is a genus of venomous marine fish, commonly known as lionfish, native to the Indo-Pacific. Pterois, also called zebrafish, firefish, turkeyfish or butterfly-cod, is characterized by conspicuous warning coloration with red, white, creamy, or black bands, showy pectoral fins, and venomous spiky fin rays.Pterois radiata, Pterois volitans, and Pterois miles are the most commonly studied species in the genus. Pterois species are popular aquarium fish.P. volitans and P. miles are a recent and significant invasive species in the west Atlantic, Caribbean Sea and Mediterranean Sea.
There are currently 12 recognized species in this genus:
Pterois lunulata
Pterois fish in the Atlantic range from 5 to 45 cm (2.0 to 17.7 in) in length, weighing from 0.025 to 1.3 kg (0.055 to 2.866 lb). They are well known for their ornate beauty, venomous spines, and unique tentacles. Juvenile lionfish have a unique tentacle located above their eye sockets that varies in phenotype between species. The evolution of this tentacle is suggested to serve to continually attract new prey; studies also suggest it plays a role in sexual selection.
Pterois species can live from five to 15 years and have complex courtship and mating behaviors. Females release two mucus-filled egg clusters frequently, which can contain as many as 15,000 eggs. Studies on Pterois reproductive habits have increased significantly in the past decade. All the species are aposematic: they have conspicuous coloration with boldly contrasting stripes and wide fans of projecting spines, advertising their ability to defend themselves.
