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 use inflation as a defensive tactic against predators. This involves expanding their stomach with water to increase their size and intimidate the predator. The duration of this defense is crucial, requiring them to maintain the inflated state for up to ten minutes.
