The stonefish is a highly venomous fish found in the coastal regions of the Indo-Pacific oceans. It is known for its remarkable camouflage, resembling a rock or coral, which helps it ambush prey. Stonefish can grow up to 14 inches long and have a stout body covered in rough, bumpy skin. These fish possess venomous spines on their dorsal fins, which can deliver a painful sting if stepped on. The venom can cause severe pain, swelling, and even more serious health issues in humans. Despite their dangerous nature, stonefish play an important role in their ecosystem as both predators and prey.
