In the animal kingdom, animals from different species might befriend each other in what is called “symbiosis,” in which they each provide a service for each other, creating a mutual relationship. For example, Oxpecker birds like to eat bugs off of rhinos and hippos. The birds get an easy meal, while the rhinos and hippos are cleaned up from parasitic bugs. When it comes to animals that have been domesticated, such as with animals kept in pets or even zoos, the animals could simply be friends who enjoy each other’s company. Here are 1o videos of animals of different species enjoying each other’s company.
