A burrowing tarantula keeps frogs as “pets” to protect its eggs from insects. The tarantula Xenesthis immanis has a mutualistic relationship with the dotted humming frog Chiasmocleis ventrimaculata. As the spider feasts on prey, discarded remains begin to pile up. This (along with the spider’s eggs) attracts ants and other hungry pests, which the frog eats up before any damage can be done to the nest. In exchange, the tarantula provides the frog protection from predators.
