A ball can be difficult to devour

When at risk, the pufferfish live up to their name and pump up into a ball when an attacker strikes, acting as a deterrent – admittedly this seems more impressive when they do this as opposed to frightening for us humans. They turn into a ball by pumping water out of their oral cavity into a bag-like extension of their stomach using their strong muscle structure.

It is as poisonous as it is yellow

The nerve poison of the lemon-colored pufferfish contains tetrodotoxin and is one of the strongest known, non-protein poisons. Even a dose of only ten micrograms/kilogram of body weight is lethal to humans. The effect of the nerve agent is particularly treacherous: Victims are paralyzed, but remain with full consciousness until death by asphyxiation or cardiac arrest occurs.

Is it true, that ...?

... the poisonous pufferfish is eaten? Unfortunately yes. Its muscle meat is even seen as a specialty in Japan, this is known as 'Fugu'. However, many people have paid for it with their lives. After more than a 100 people were being poisoned each year, strict laws were introduced in 1958 to govern the sale of pufferfish. The number of deaths has since shrank to just a few people per year.
