There's something extra adorable about unlikely animal-human friendships.
Maybe it's because deep down inside, we all really want to see everybody get along. I mean, why else would we get all misty-eyed when a wolf ends up taking care of a lost baby instead of tearing them to shreds?
Whatever the reason, it's awesome to witness. Especially when the animals aren't really known for being cuddly or affectionate. Like this weird looking fish who's been absolutely obsessed with Japanese diver Hiroyuki Arakawa for a whopping 25 years.
