Scorpionfish are members of the family Scorpianidae, which includes many of the world’s most venomous species. One genus is the Lionfish, but many of the other genii are bottom-dwellers. The Red Rockcod found in Australian waters is one example, another is the Devil Scorpionfish, (Scorpaenopsis diabolus), also called the False Stonefish.
Found throughout the Indo-pacific, this fish is perfectly camouflaged to whatever substrate it lives on. An ambush predator, it simply lies on the bottom and sucks its prey straight into its mouth – whole. This fish has become so adept in this lazy lifestyle – it appears to have lost the desire to swim.
This video shows how well it can camouflage itself – and how quickly it can move (not!)
