About:

Plankton are organisms drifting in the oceans and seas. Zooplankton refers to all the animal plankton, which encompasses a huge number of different species. Jellyfish, crab larvae, fish larvae, copepods and amphipods are all types of zooplankton. They vary in size from a fraction of a mm to the largest jellyfish which are 2 metres wide.

Where:

In our seas and in fresh water too.

Fantastic facts:

Relative to their size (typically about 1mm), copepods are the fastest moving organisms on the planet! Zooplankton are a food source for some of the largest sharks in the sea, including basking sharks which visit British waters.
