The name of the spiny pufferfish reflects this fact. These spines on the body of the spiny puffer fish evolved from scales. In other words, the scales of the spiny puffer fish are movable spines. When the puffer fish's body expands, the spines can stand upright, and the bases of the spines are connected to each other to form a continuous deck. These spines can be used to protect itself from enemies.
Normally, these spines are close to the surface of the body, smooth and smooth. Once it encounters a threat or is disturbed, the puffer fish will quickly swallow seawater or air, causing its body to expand rapidly. The spines all over its body stand up, forming a ball with burrs. It floats on the water with its belly facing up, drifting along the current. How dare the enemy touch it! The pufferfish relies on this ability to resist fierce enemies.
When the danger is over, the spiny puffer spits out the seawater and air it swallowed, and its spherical body lined with spines quickly deflates and returns to its original shape. At this time, the terrible thorns also fell down and clung to the body, so the spiny fish slowly swam underwater again.
