Scottish Highlands-based photographer Peter Jolly has captured images of a juvenile bottlenose dolphin playing with a jellyfish in the Moray Firth.
The photographs show the youngster flicking the creature into the air with its nose.
The Moray Firth and North Sea provides habitat for the world’s most northerly resident population of bottlenose dolphins.
Research published in 2012 suggested the population was “stable” with almost 200 animals. The species is protected by European Union rules.
