Which British river creature do you think deserves more spotlight?

Once nearly wiped out by pollution and hunting, otters have made a remarkable return to UK waterways. Spotting one sliding into a river at dusk feels like winning the wildlife lottery.

Immortalised by Kenneth Grahame, the water vole is sadly one of Britain's most rapidly declining mammals. Catching a glimpse of one plopping into a stream is both delightful and quietly heartbreaking.

Few sights along a British river beat a kingfisher darting past like a tiny jewelled arrow. They're technically common, yet most people spend years trying to spot one properly.

Quietly clinging on against invasive American signal crayfish, the white-clawed crayfish is a genuine underdog story playing out in rivers across the UK. Small, scrappy, and seriously overlooked.

These extraordinary molluscs can live for over 100 years and are among the most endangered freshwater species in the world. Not exactly glamorous, but their story is utterly compelling.
