Sea Jellies

Sea Jellies
Fun Facts

Fun Facts

  • Sea jellies appeared before dinosaurs. They have been living on Earth for over 650 million years.

  • The tentacles of sea jellies are used for feeding and defense. With cells containing barbs and venom, these body structures can sting and kill their prey. One of the most venomous species, sea wasps (Chironex fleckeri), can kill a human in a few minutes.

Threats & Conservation

Sea jellies are important members of the marine food web as they act as predators and preys. Climate change and pollution has altered the population sizes of some sea jelly species, thus affecting other members of their ecosystem.
