The UK has a rich history of marine biology, with famous scientists such as Charles Darwin who did pioneering work in the field, and strong research institutions with international expertise in marine sciences. So, surely then, scientists must know everything there is to know about the country’s coasts and rockpools? Unfortunately not. While there are scientific names for the overwhelming majority of marine species on the country’s shores, we don’t necessarily know everything about the organisms themselves – or what lives inside them.
