The victim is then passed to the mouth of the jellyfish and swallowed. Some jellyfish can inflict painful and even dangerous stings to people. Jellyfish called sea wasps inject their victims with a poison that is deadlier than any snake venom. Some people have died less than three minutes after being stung by a sea wasp. Sea wasps are found near the coasts of northern Australia and the Philippines.
Scyphozoan jellyfish produce their young from eggs.
Each egg develops into a tiny polyp, a stage in which the animal looks like a hollow cylinder. The polyps attach themselves to the sea bottom. The jellyfish grow from the polyps by a process called budding. They are arranged on each polyp like a stack of saucers. The jellyfish, when they reach a certain size, detach from the polyp and develop into adult jellyfish.
