Commonly known as the Lionfish, Pterois are venomous fish. There are 18 needle like projections on the top of the pterois that are used as a defence mechanism. The venom is extremely painful to humans and could cause nausea and breathing difficulties but they are often not fatal. They rely purely on their fast reaction and body camouflage to feed on their prey. They live in the Indo-pacific regions and can grow up to 40cm long while the average is only about 30cm for a fully grown pterois. Pterois have stripes on their scales to camouflage with the coral and to hide in rock cracks to be able to ambush the prey!
