Chironex fleckeri, Australian Box Jellyfish

Hello! Welcome to this webpage all about the most venomous animal on the planet. You can learn all about the species Chironex fleckeri, commonly known as the box jellyfish, on this site. This Cubozoan is responsible for more human deaths than stonefish, sharks, and crocodiles combined throughout the globe. Go to the Interactions page to learn more! In Australia, at least one death is recorded every year. To learn more about where this animal lives, check out the Habitat page! Along with its nearly invisible structure and dreadfully venomous tentacles, this box jelly is considered to be the most venomous organism on the planet. Swimming just off the shores of Australia, the Chironex is awaiting its prey, prepared to strike on its next attack. You can learn how this box jellyfish eats by visiting the Nutrition page. However, its deadly tentacles are only a small part that this jellyfish has to offer. This jellyfish contains many Adaptations that allow it to be such a deadly predator.

While navigating through this website, I encourage you to learn about the beautiful, yet deadly box jellyfish, Chironex fleckeri. It may be hard to distinguish them from other jellyfish, but this site is a place where all of those doubts can be turned into a clear understanding of this species.
