Spot-fin porcupine fish.

Scientific name: Diodon hystrix

Puffed up for defence
The porcupine fish inflates by pumping water into its stomach, stretching its skin and forcing its spines upright – a much less appealing meal for any predator.

Amazing ability: Expanding to scare off predators

Where to find them: You can see spot-fin porcupine fish sheltering near tropical seashores around the world
