box jellyfish

Jellyfish are virtually road bumps in the ecosystem. They have no brain and only serve to eat zooplankton from the world's oceans. To do so, they extend their tentacles (ranging from 10 to 60), which secrete a toxic substance. These tentacles range from a few inches to 15 feet long.



The box jellyfish, also known as a sea wasp, lives off the waters of Northern Australia and is the most poisonous sea creature in the world. This translucent being patrols the beaches, basically waiting for contact with its victim. The simple act of stepping on a tentacle can signify death in four minutes
