Pufferfish, as their name indicates, have the ability to ‘puff’ themselves up in order to intimidate predators. This is accomplished by filling a distensible stomach with water through rapid gulping which can increase their size to three or four times their original volume. Pufferfish must be capable of maintaining inflation for up to ten minutes in order to outlast the attention span of their predators.
Pufferfish are known for puffing themselves up as a defense mechanism against predators. They achieve this by rapidly gulping water into their distensible stomachs, which expands their size to three or four times their original volume. To deter predators, they must maintain this inflated state for up to ten minutes.
