Pterois, commonly known as Lionfish, is a genus of venomous marine fish found mostly in the Indo-Pacific. Pterois is characterized by red, white and black bands, showy pectoral fins and venomous spiky fin rays. The potency of their venom makes them excellent predators and poisonous to fishermen and divers. They are well known for their ornate beauty, venomous spines and unique tentacles. “Majestic lion fish on the prowl” photographed in Mactan, Cebu by Paul Cowell.
