The Boxer Crab, also known as the Pom-Pom Crab wears anemonies on it's claws that it uses for catching food and fending off predators. They get the anemonies on their claws by coaxing the anemonies into releasing from their sedentary home by massaging them. The relationship between the two is debatably mutualistic, how much the anemone actually benefits from this is not completely clear. I higly recommend the Octopus Lady's video on them.
