Weedy Scorpionfish

Found singly, blending in with corals, rocks, and weeds, over soft mud and sand bottoms, of coral and rocky, current swept channels close to reefs, rich in algae growth. Colour varies. They feed nocturnally, on small fish and invertebrates.

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.
