Clip Description

Jellyfish are the oldest multi-cellular animals on the planet. They were here long before the dinosaurs, having existed on Earth for at least 500 million years. Although different species of jellyfish differ greatly in terms of their shape, size and colour, all jellyfish have no brain, heart or eyes. Their smooth bag-like bodies have tentacles attached to them that are armed with stinging cells.

In this fascinating clip, cassiopeia jellyfish can be seen clustering in the calmest and sunniest spots of the Atlantic Ocean.
