There are more than 200 different species of Jellyfish. Jellyfish are invertebrates and they come in different shapes and sizes. The longest jellyfish is the Arctic lion’s mane whose tentacles may stretch up to 100 feet in length.

Jellyfish can be found in all the world’s oceans and even in freshwater. Jellyfish are 95% water. They have no heart, brain, blood, or gills.

The body of the Jellyfish is called a bell. What they do have is a mouth, tentacles, and arms around their mouth. They use their arms around their mouth to help sense and find food that ends up inside their mouth.

Jellyfish can sense smells and tastes using chemo receptors. Also they can remain balanced in the water. Jellyfish eat small animals called zoo plankton.

An adult female jellyfish produces eggs and holds them around her mouth. The male jellyfish releases sperms into the water that the female jellyfish collects with her tentacles.

Then the female jellyfish fertilizes her eggs.The mother jellyfish carries them around until she finds a hard place like a rock or a shell to put them.

Jellyfish have only a few predators because of the fact that they can sting. A few of their predators are the Banner fish which are not bothered by their tentacles.

Arrow Crabs gobble them up in one bite. Turtles, certain fish and snails nibble on the jellyfish’s tentacles.

The Arctic jelly fish of the North west Atlantic has the largest reach for an animal. One of these creatures washed up in a beach in 1865 had a body 7.5 feet across.

Its tentacles measures 120 feet giving it a possible span of more than 240 feet.
