How do jellyfish live?

Jellyfish are simple, gelatinous animals that live in oceans, seas, and some freshwater environments around the world. They have a soft, translucent body and move by pulsating their bell-shaped structure to propel themselves through the water. Jellyfish are carnivores and feed on small plankton, fish larvae, and other tiny marine organisms that they capture with their tentacles, which contain stinging cells called nematocysts. These tentacles deliver venom to immobilize prey. Jellyfish do not have a brain, but they possess a simple nerve net that helps them respond to environmental stimuli. They can be found at various depths, from shallow waters to the deep sea, depending on the species. Jellyfish reproduce both sexually, with males and females releasing eggs and sperm into the water to fertilize, and asexually, through a process called budding. Some species also have a complex life cycle involving different stages, including medusa (adult form) and polyp (immature form).
