The Box Jellyfish
The box jellyfish is the most poisonous living thing on Earth. It needs this venom because it’s so fragile that even a struggling shrimp could tear it apart, so it has to kill that shrimp instantly. During some periods of time in Australia, some beaches have to have jellyfish nets to keep this jellyfish out so people can swim. The box jellyfish is also called the chironex or sea wasp.
