A pincushion

On first glance, the longspined porcupine fish looks endearing with its large head and big round eyes. But when it feels threatened, it inflates itself by swallowing water to become a large ball with protruding needle-like spines that can pierce a predator. It does this to protect itself from its enemies.

Enemies

The longspined porcupine fish has very few enemies because it has a highly effective defence system. But sometimes a longspined porcupine ends up in the jaws of a shark.

Poisonous

Some longspined porcupinefish are very poisonous because they live in a symbiotic relationship with bacteria that produce a toxin. The toxin builds up in the porcupinefish's skin, liver and sex glands.
