According to the Sea Watch Foundation, 30 whale and dolphin species have been recorded in UK waters, with the bottlenose dolphin and the harbour porpoise among the most popular.
Dolphins are often spotted along the North East coastline and recently two dolphins were seen near Roker Pier.

The 'Roker and Seaburn dolphin watch’ Facebook group is also a good way to keep up to date with the latest sightings.
