Common Lionfish

The red lionfish (Pterois volitans) is a venomous coral reef fish in the family Scorpaenidae, order Scorpaeniformes. It is mainly native to the Indo-Pacific region, but has become an invasive species in the Caribbean Sea, as well as along the East Coast of the United States and East Mediterranean and also found in Brazil at Fernando de Noronha.

P. volitans and a similar relative, Pterois miles, have both been deemed invasive species. Red lionfish are clad in white stripes alternated with red, maroon or brown stripes. Adults in this species can grow as large as 47 cm (18.5 in) in length, making it one of the largest species of lionfish in the ocean, while juveniles are typically shorter than 1 inch (2.5 cm). The average red lionfish lives around 10 years. As with many species within the family Scorpaenidae, it has large, venomous spines on its dorsal fin (13) as well as other venomous spines on its pelvic fins (2) and anal fins (3). It is these fins together with the other long non-venomous fins which create an appearance similar to a mane, giving it the common name "lionfish".
