True Wild Life | Jellyfish | Jellyfish (also known as jellies and sea jellies) are boneless animals that float freely through the world's oceans. Although jellyfish exist in our oceans worldwide they are particularly prominent in coastal areas. Jellyfish can be found in all shapes and sizes from just a few inches in diameter to well over a metre. There are thought to be around 2,000 different species of jellyfish, the most common being the big, colourful ones found in warmer coastal areas. There are four different types of jellyfish that are categorised by their shape and the way in which they behave.
