Pufferfish, also known as blowfish, are interesting creatures in the world's oceans. They are easily recognizable due to their spiny, swollen bodies that can be inflated when threatened.
Pufferfish come in all shapes and sizes, ranging from the zebra puffer, a large species, to the dwarf and dwarf angry puffer, which are very small in comparison.
These fish have modified spines with a venomous toxin known as tetrodotoxin which can be fatal to humans.
Pufferfish have strong beaks that crunch into mollusks and crustaceans as part of their diet.
Females can lay over 2,000 eggs at one time, which can take up to two weeks to hatch.
The diet of the pufferfish doesn't consist solely of seafood; they also consume plant matter such as seaweed and algae.
Different pufferfish may be found in freshwater and brackish waters, depending on the species.
Like most fish, the pufferfish uses a tail fin to move up and down instead of side-to-side.
Some pufferfish species have fused pelvic fins, giving them a more developed swimming capability.
They also use their fins as seat-like devices to rest in crevices on the ocean floor.
Some pufferfish can produce sounds to communicate with other individuals.
