Did you know that the puffer fish inflates?

In fact, this defense strategy is pretty much complete. As part of its defense mechanism, this strange animal, in addition to using its poison when feeling trapped or threatened, reacts quickly by swallowing water, which increases its volume considerably until it becomes a ball.

In this state it can hardly enter the mouth of a predator. But, even if he swallows it before it inflates, he will pay with his life for the audacity of taking it to his mouth using his well-known deadly poison.

Also, when taken out of the water, the puffer fish inflates since it has the same capacity to swallow air as water.
