Several studies have shown that animals can form friendships with members of other species — and these bonds can last a lifetime. In fact, some animals form even stronger connections than people do.

We at Smalljoys totally agree with these studies, and we’ve found some photos as proof of very unexpected yet awesome friendships. There’s also one surprising and very cute bonus at the end of the list.
