You can find many examples of inter-species friendships. Remember Tarra the elephant and Bella the dog?
Here is another sweet odd couple right out of nature. In Jacksonville, Florida, a young dog named Rio plays whole-heartedly with a wild river otter. Otters enjoy playing — as do dogs — so I suppose this should be no surprise.
Watch them enjoy each other’s company! Apparently, the friendship lasted for several months and then the otter got bored because he never returned.
