Fun Porcupine Fish Facts For Kids
Gallery
Porcupine fish, commonly known as balloonfish, blowfish, or globefish, is a medium to large-sized fish that belongs to family diodontidae and order tetraodontiformes. The porcupine fish scientific name is Diodon hystrix.
They usually inhabit shallow temperate and tropical seas around the world and live in large schools of thousands of porcupine fishes. These fishes are greyish-tanned colored and are uniformly covered with small, black specks.
They have a white underbelly and sharp spines which are basically scales that have been modified into spines to protect the fish from predators. Certain species of this fish are poisonous, containing tetrodotoxin in their liver and ovaries.
These fishes usually move slowly and have the ability to inflate themselves by filling their bodies with water or air. This is also a defence mechanism that allows them to avoid falling prey to sea creatures with bigger mouths.
While in the inflated state, their spikes radiate outwards. Owing to these defences, these fishes do not have too many predators, however, killer whales and sharks might sometimes prey on them.
Porcupine fish are apparently a delicacy in Cebu, the Philippines, where they are eaten as exotic seafood. Continue reading below to find out more interesting facts about these fishes. If you like this article, then be sure to check out our articles on hogfish and candiru.

What does a porcupine fish do to protect itself?
Porcupinefishes have the ability to inflate and blow up to a greater proportion by swallowing large quantities of either water or air. This allows the fish to grow to almost three times their normal size, thereby making it impossible for many predators to hunt them.
They also have long spines which radiate outwards when they are inflated. Apart from these two defences, a lot of the porcupinefishes are also poisonous. Thus, owing to these factors they do not have too many predators.
What happens when a porcupine fish puffs up?
The porcupinefish can inflate its body with air or water and upon doing so it becomes thrice its normal size. They also start radiating their long spines outwards towards any sea creatures which might try to attack them.
This is a defence technique used by them to avoid falling prey to animals with a mouth size that is bigger than their normal body size.
