    Jellies look like umbrellas. Some are large and brightly colored. The colors of a jellyfish are red, orange, blue, purple, pink, etc. Like stated before, they can also be transparent or close to transparent. Their tentacles can grow to be 60 m. (200 ft.) WOW!!!

Where do Jellyfish Live?

     Most jellies live in the ocean but some do live in freshwater places like rivers and lakes. They are found in every ocean from the surface to deep inside the water.The deadliest jellyfish are found in and near Australia. An example of a freshwater jellyfish is the Craspedacusta sowerbyi. They are a freshwater jellyfish that inhabit nearly all continents, but they are very rare in Africa.

Predator and Prey

    Some of the prey that they eat are zooplankton, small fish eggs, a whole fish, and also larvae. Some of the predators of the jellyfish are tuna, sharks, swordfish, sea turtles, and a species of Pacific Salmon. Jellyfish are tertiary consumers on the food chain.
