Box jellyfish eat shrimp, fish and worms by using their tentacles to sting prey and then pulling the prey into their mouths. Many species of jellyfish eat their prey in this manner.
The box jellyfish can eat its prey in less than one minute. It is not able to sting all predators, however, such as sea turtles. Sea turtles happily eat box jellyfish for a meal on a regular basis.
The box jellyfish is also known as a "sea wasp" or a "box jelly." This species of jellyfish is considered to be the most advanced out of all of the jellyfish species because they can move throughout the water instead of merely floating with the flow of the water as other jellyfish do.
