What does a Jellyfish look like?
Beauty is in the eye of the beholder when it comes to jellyfish. With over 1,500 species in a myriad of colors and sizes, they can either be seen as floating pieces of colorful art (some even give a light show) or as blobs of goo capable of ruining a day at the beach. There are four different types of jellyfish that are categorised by their shape and the way in which they behave.
Where do Jellyfish live?
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.

Jellyfish use their tentacles to stun their prey before grabbing onto it and bringing it into their mouth. Jellyfish prey on a kinds of aquatic animals such as small fish, eggs and invertebrates along with anything else that gets stuck in their tentacles.
What are the natural enemies of the Jellyfish?
Due to the fact that many species of jellyfish are transparent, they are often hard for predators to spot. However, jellyfish are drifters and move very slowly through the water sometimes using their tentacles to propel them along. Jellyfish are eaten by humans, sharks, squid and occasionally birds.
How do jellyfish grow?
Jellyfish start their lives as small polyps on the seabed. Eventually, dozens of medusae — free swimming forms — break off the polyps and begin their journey to sexual maturity. The body of a jellyfish is bell-shaped with a mouth on the underside. Tentacles of varying lengths extend below.
How do jellyfish swim?
Jellyfish contract their fluid bodies to move, but are not very efficient swimmers. Instead, water currents usually determine their path and many find themselves washed up on beaches.

Older than sharks and dinosaurs, jellyfish have lived on earth for over 650 million years.
