Reef Scorpionfish

Found singly or in pairs, well camouflaged, close to ceilings in caves and under ledges, over coral and rocky reefs.
They feed nocturnally on crustaceans and small fish.

Scorpionfish are masters of camouflage, enabling them to lie in wait for their victims to come close, before lunging forward and inhaling their prey with their large mouths.
When disturbed they raise the spines along their backs and will usually move off out of harms way, however, if cornered they are able to charge at considerable speed.
Highly dangerous and poisonous with venomous spines along its back if trodden on etc.
