Despite being poisonous, many chiefs use them in specialty dishes. The poison, tetrodotoxin, is found in the skin, gonads, liver and muscle tissues of the fish. However, poison is not the pufferfish’s only self defense mechansim. As its nick name suggests, the pufferfish can inflate itself to make it difficult for predators to swallow it.

Most of the box jellyfish’s poison are inside the animal’s tentacles. They are called nematocysts. When the jellyfish attaches to the skin of the victim, the toxins enter the victim’s body through a bite. The toxins will rapidly increase blood pressure and blood flow. This leads to heart attack and the victims eventual death. If stung, apply heat or ice on the sting. Soaking the wound with vinegar can also provide some relief against the pain. Make sure you soak the site of the wound for about half an hour.

Box jellyfish shrink in size when not eating. In fact, the box jellyfish can shrink by more than 30% of its original body weight within 24 hours if it does not find food. Smaller box jellyfish consume prawns while larger box jellyfish feed on small fishes.
