Colourful close up images of plankton, the tiny creatures that hold the key to survival in the world's oceans, are going on show at London Zoo - as part of The Royal Society's 350th anniversary celebrations.
They are to feature in a book being compiled by the man who captured them - Royal Society Research Fellow, Dr Richard Kirby from the University of Plymouth. Here, he explains why plankton should not be ignored.
Dr. Richard Kirby is also a Sir Alister Hardy Foundation for Ocean Science (SAHFOS) research fellow.
