Poisonous scorpionfish


Poisonous scorpionfish are found in the Indian and Pacific Oceans, the South China Sea, the East China Sea, and the Taiwan Sea. Common species include the tiger scorpionfish, the ghost scorpionfish, and the poisonous scorpionfish. The scorpionfish often lives among the rocks near the coast and in the bottom waters near the coast. It often lurks in caves, reef crevices, seaweed beds or buried in the sand, feeding on small bottom-feeding carnivorous fish. The scorpionfish rarely moves. Its body shape and coloration are similar to the surrounding environment.
