Deadly Pufferfish

At rest, the pufferfish looks like a regular fish, but when it’s alarmed, watch out! Pufferfish quickly suck in water or air to blow up like a balloon. Many also have sharp spines for protection. These two defenses chase away most enemies. However, the pufferfish also produces one of the deadliest poisons in the world. Eating even a tiny amount of pufferfish is enough to kill many animals, even humans. Amazing photographs allow readers to swim in for a close-up view of these deadly creatures.
