Wild Five Coastal - Leah goes in search of dolphins

Leah's been to the Moray Firth in Scotland where a pod of rare dolphins are living - but they're facing some big challenges.

Bottlenose dolphins have lived in the area for over 100 years and are the only surviving population of their kind in the North Sea.

Wildlife campaigners are concerned for their future - noise from industrial activity, overfishing and sonar from military ships affecting the way the dolphins communicate all could lead to the dolphins moving away from the area.
