Pufferfish

Pufferfish (also known as blowfish and fugu) are a group of fish species that belong to the family Tetraodontidae. They are known for their unique ability to inflate their bodies by swallowing air or water, which they use as a defense mechanism against predators.

Description

Pufferfish are generally small to medium in size, although some species can reach lengths of up to 100 cm. They have a round, bulbous shape that is accentuated when they inflate their bodies. Their skin is typically rough and covered in spines, which become more pronounced when the fish is inflated.

Behavior

Pufferfish are known for their unique defensive behavior. When threatened, they can inflate their bodies to several times their normal size, making them difficult for predators to swallow. Some species also have spines on their skin, which become erect when the fish is inflated, providing additional protection.

Diet

Pufferfish are primarily carnivorous, feeding on invertebrates and other small marine organisms. Some species also consume algae and other plant material.

Toxicity

Many species of pufferfish are highly toxic and can be deadly if consumed. The fish's organs, especially the liver and ovaries, contain a potent neurotoxin known as tetrodotoxin. This toxin is up to 1,200 times more poisonous than cyanide and can cause death in humans.

In culture

Despite the risks, pufferfish are considered a delicacy in some cultures, particularly in Japan where it is known as fugu. The preparation of fugu is strictly regulated in Japan and can only be performed by licensed chefs.
