Puffer is a benthic fish in warm temperate and tropical coastal waters, inhabiting the middle and lower layers of the ocean, and a few species enter freshwater rivers. When encountering external danger, the whole body floats to the surface in a spherical shape, and at the same time, the small thorns on the skin stand up to defend themselves.
