"I was a teen and snorkeling with my dad in Hawaii. Really enjoying ourselves, tons of fish and some smaller sea turtles and no other people. All of a sudden a sea turtle the size of a mini cooper starts swimming towards us – came completely out of the dark of the ocean. Scared the piss out of me (literally), I’ve never swam back to fast in my life. We got back to the shore and walked around to some cliffs and could see the turtle’s shell on the surface, it was easily the size of a small car."
