Stonefish is the most venomous fish in the world. Some species of stonefish live in the rivers. Stonefish lives close to coral reefs and underwater rocks. It often lies buried in the sand in the shallow water. Stonefish is consumed as delicacy in Asia and kept in aquariums throughout the world due to its unusual appearance.
Body of stonefish is covered with encrusted brown or grey skin, with red, orange or yellow patches. Thanks to specific texture and color, stonefish easily blends with its environment (it looks like a stone or a part of the coral reef).
