It was called "lungfish" in ancient times. Generally speaking, it refers to the fishes belonging to the family Dactylidae, Triodontidae, Tetraodontidae and Cynodontidae in the order Dactylidae.
The puffer fish is a benthic fish in warm temperate zone and tropical coastal waters, inhabiting the middle and lower layers of the ocean, and a few species enter the freshwater rivers. When encountering foreign enemies, the abdominal sac expands rapidly, making the whole body float to the surface in a spherical shape, and at the same time, the small thorns on the skin stand up for self-defense.
