Genus Pterois is a group of fish commonly known as lionfish. Lionfish are native to the Indo-Pacific region, but were introduced to the Atlantic Ocean through aquarium releases and have since become an invasive species. Synonyms for genus Pterois include Pterois volitans, Pterois antennata, and Pterois russelii. These species are known for their striking red, white, and black stripes and their venomous spines, which are used for defense against predators. Lionfish are popular in the aquarium trade and their consumption has been promoted as a means of controlling their populations in non-native habitats. However, caution must be taken when handling these fish due to their venomous spines.
