Danger in disguise

No, it's not a rock. It's found underwater in the coastal areas of the western Pacific Ocean, but neither is it coral. It just happens to be one of the most venomous fish in the world, though I saw it safely behind glass at the Manila Ocean Park. The Estuarine Stonefish (Synanceia horrida) camouflages itself among rocks at the bottom of tropical reefs, where it lies in ambush for shrimp and small fish to swim by. If you are having a difficult time seeing the fish, try to locate its deeply-frowning mouth on the left, then its dark eye bugging out, one fin at the bottom of the tank, and finally, the venomous spines which run along its top. See it now?
