Hundreds of wildlife enthusiasts are expected to gather along UK coastlines over the next 10 days to count and record whales and dolphins.

The National Whale and Dolphin Watch, taking place from 26 July to 4 August, is hosted by the Sea Watch Foundation and aims to get volunteers to observe and record sightings of the UK’s most impressive marine mammals.
