Ben Burville shot incredible video in Britain's North Sea that shows a grey seal holding his hand with its front flipper.
Burville has been taking video of the seals and studying their behavior for more than 12 years. The doctor says he finds peace and tranquility being in the company of the marine animals.
He says the seals are exceedingly gentle when he holds their flippers underwater.
