Jellyfish

Box Jellyfish

There are about 1270-1770 different species of jellyfish under the classes of Scyphozoa, Staurozoa, Cubozoa and Hydrozoa. They are found in every ocean around the world, located in either the deep sea or shallow water. There are also freshwater species that are less than an inch in diameter and have no sting as well as no colour. They use there tentacles to attract there prey and as the prey falls into them the tentacles send an electrical shock through the prey's body. The Portuguese Man of War is probably my favourite jellyfish as it actually not classified as a jellyfish as per say, as it is actually made up of individuals called zooids. Also the top of them floats on the surface of the water instead of many jellyfish that actually float in the water. Jellyfish are another example of intriguing life in our oceans.
My next post will be about sharks.
