"This whole article is kind of adorable! The sea snakes have bad vision, so they come over thinking the diver is a 50-foot female snake, then they lick the diver to figure out what it is, then swim away disappointed. Then, they forget they already licked you, see you again, and lick you again. And if you swim away, they think it's part of a mating ritual, so they follow you so they can lick you!"
