<\/h3>\nJellyfish are found in all the world\u2019s oceans, from the surface to the deep sea.\u00a0 Most live in saltwater, although there are a few species that live in fresh water.\u00a0 Jellyfish have soft bodies and swim freely for much of their adult lives.<\/p>\n
There are hundreds of different species of jellyfish.\u00a0 Adult jellyfish (sometimes called jellies) have an umbrella-shaped bell, with tentacles that hang from the bell.\u00a0 Different species of jellyfish live in every ocean, and some species live in fresh water.\u00a0 Some live near the surface, while others live in the deep sea.\u00a0 They have soft bodies, unlike the vertebrate skeletons of fish.\u00a0 They move through the water efficiently by rapidly expanding and contracting their bell-shaped bodies to push water behind them.<\/p>\n
Most species of jellyfish eat plankton, small crustaceans, fish eggs, small fish, and other smaller jellyfish.\u00a0 \u00a0Their prey are caught in the vortex created by their movement through the water, then entangled in tentacles.\u00a0 They are preyed upon by larger jellyfish, tuna, shark, swordfish, and sea turtles.\u00a0 Jellyfish tend to gather in large swarms, often called \u201cblooms\u201d, and some invasive species of jellyfish grow in new habitats, overwhelming other populations of marine creatures.\u00a0 They are relatively more adapted to survive in warmer waters that contain less oxygen but more nutrients, such as agricultural runoff.<\/p>\n
Many species are poisonous, with toxic stingers on the tentacles.\u00a0 Most stings are not deadly, but a few species are highly venomous, and their stings can be fatal.\u00a0 The sea wasp and other forms of box jellyfish hunt their prey rather than drifting toward it.\u00a0 Beaches in Australia have warning signs against stinging jellyfish. The most effective protection against jellyfish stings is wearing protective covering, such as a wetsuit or even pantyhose, as the stinging cells cannot touch the skin and react with it chemically.<\/p>\n
<\/h3>\nEggs develop into free-swimming larvae.\u00a0 The free-swimming larvae settle onto firm surfaces and become polyps, similar to sea anemones.\u00a0 The polyp then breaks off to become an adult medusa, or jellyfish.\u00a0 Life spans vary depending upon the size and species.\u00a0 The smallest species may live only a few hours, but many large coastal species live for months.\u00a0 Aquarium jellyfish can live several years, as they have regular food and are tended carefully.<\/p>\n
