    Jellies live in all the oceans of the planet and at every depth from shallow warm waters to the coldest darkest deepest waters. They do not have eyes as such to see where they are going but have numerous sensors to assist them – they are able to orientate themselves towards the light and have specialised internal cells called statoliths which enable them to perceive gravity.

    One defining characteristic of all jellies is that to some degree or other, they all sting. They come in all shapes colours and sizes and the Lionsmane jelly can grow to be 6-8 feet in diameter and 70 feet long. The size of the jelly is determined by the abundance of its food source. The biggest predator of jellies is other jellies. Sea anemones may eat jellyfish that drift into their range. Other predators include tunas, sharks, swordfish, sea turtles and penguins. It is possible for jellies to become a dominant species in an ecosystem where there has been overfishing and hence the removal of predators of jellie larvae. It can then become difficult to restore the previous balance.
