One would think that badgers would be better suited to symbiotic connections with mushrooms and snakes. Instead, they actually share a very unusual, mutualistic relationship with coyotes – an animal better suited for chowing down on them rather than encouraging survival. Coyotes eat ground squirrels and prairie dogs, but their subterranean lairs prove a challenge when it comes time to feed. Badgers, however, possess more than adequate digging abilities. Also a fan of the underground rodents, badgers occasionally team up with far faster coyotes for tag-teamed hunts. No matter where their prey may run, 1 of the 2 predators is there to catch them and share the spoils with his or her partner. Biologists believe that this symbiotic system is around 30% more efficient than if either animal were to hunt solo.
