There are plenty of examples of mutualism in nature. Be it the rhinosaurus and the oxpecker, clownfish and sea anemones, or sharks and remora fish, there are unlikely besties in the wild that work ...

If you're ever in need of an impressive biological story, look no further than the examples of mutualism, when two totally unrelated species not only coexist, but both benefit from the relationship.

We do this every day with domesticated species such as dogs or horses: They help us find something or carry us somewhere, and, in return, we provide them with food and shelter. In biological terms, ...

In a group of plants that is famous for luring its pollinators into a death trap, one species offers its flowers as a nursery in exchange. The discovery blurs the line between mutualism and parasitism ...

Endosymbiotic relationships—in which one organism lives within another—are striking examples of mutualism, and can often significantly shape the biology of the participant species. In new findings ...
