The Red Lionfish (Pterois volitans) is a fish venomous who live coral reef in the family Scorpaenidae, order Scorpaeniformes. Pterois volitansis natively found in the Indo-Pacific region, but has become an invasive problem in the Carribbean Sea, as well as along the East Coast of the United States. Red lionfish are clad in white stripes alternated with red/maroon/brown stripes. Adults in this species can grow as large as 38 cm in length, making it one of the largest species of lionfish in the ocean. The average red lionfish lives around 10 years. As with many species within the family Scopaenidae, it has large, venomous spines that protrude from the body, similar to a mane, giving it the common name lionfish. The venomous spines make the fish inedible or deter most potential predator. Lionfish reproduce monthly and are able to quickly disperse during their larval stage for expansion of their invasive region. No definitive predators of the lionfish are known, and many organizations are promoting the harvest and consumption of lionfish in efforts to prevent further increases in the already high population densities.
