A group of young seals have delighted divers with their amorous underwater behaviour.
The grey seals were in a playful mood as they fooled around in the waters with photographers Caroline and Nick Robertson-Brown.
The British pair organise trips near the Puffin Islands in Anglesey and Farne Islands in Northumberland under the name Frogfish Photography and the experienced photographers and divers are enthusiastic wildlife conservationists.
Nick, a member of the Green Party, is currently running in the election for the Altrincham and Sale West constituency and is hoping to raise awareness of the need for marine conservation zones.
The couple were thrilled by the friendly young seal pups which were bold enough to swim up close and inspect the cameras and flippers of the keen photographers.
Caroline, said: "We have been diving with the seals of the Farne Islands and Puffin Island for about 10 years now.
"They are an iconic British marine species, and we are lucky enough to have protected them in our waters and saved them from extinction.
She added: "When diving with the seals we are usually in quite shallow water, up to 10m in depth and sometimes right at the surface.
"To be honest, they are a bit like diving with puppies who want attention all the time."
