Have you ever seen an animal hitch a ride with another animal? No? Well, your day’s about to get a whole lot better.

We were so amazed by Australian photographer Robyn Malcolm’s photo last week, capturing a seal riding on the back of a humpback whale off the coast of New South Wales, that we decided to look into this phenomenon of animals hitching a ride with other animals.

It turns out animals all over the world are doing it and there’s even a Tumblr page devoted entirely to the cause!
