The Museum has been monitoring whale, dolphin and porpoise strandings in the UK since 1913. More than 14,000 animals have been reported to us, giving us a unique insight into their lifestyle and the threats they face.
If you find a stranded whale, dolphin or porpoise, you can get involved by recording some important details that will help us learn more about our marine mammals.

All whales, dolphins and porpoises are cetaceans. The name comes from the Latin cetus, meaning 'large sea animal'. Cetaceans are marine mammals.
A sea creature washed up on a beach or river bank that can't get back out to sea becomes known as a stranding. Animals may wash up already dead, or die as a result of becoming stranded.
