(NBC) - There's a good reason why seals are called dogs of the ocean.
Just watch this video by British diver Ben Burnville.
He has been diving off the northeast coast of England in the Farne Islands and has become friendly with a number of seals.
One, who he calls his "Dive Buddy," always checks to make sure his mask fits properly.
The video shows one seal hugging him in a tight embrace and cuddling with him!
