the marine organisms are predominantly translucent which makes them very difficult to identify - they are bell-shaped with small stinging cells in their tentacles which they use to paralyse prey.

they are also, fascinatingly, composed of more than 98% water - there are a vast number of different species, and vary in size from 2.5 centimeters to around 2 metres.

jellyfish have inhabited the world's seas for over 650 million years, dining on a diet of fish, prawns, crabs and plant-life - while many variants rely entirely on the currents to determine their locomotion, others squirt liquid from their mouths to propel themselves forward.
