Power Struggles in Naked Mole Rat Colonies

An all-out "naked mole rat war" has broken out at Smithsonian's National Zoo, after the queen of the colony was mortally wounded by one of her own children. Short Wave's Pien Huang and Margaret Cirino visit the battleground – a series of deceptively calm-looking plexiglass enclosures at the Zoo's Small Mammal House. There, the typically harmonious, eusocial rodents are now fighting their siblings with their big front teeth to determine who will become the new queen. Pien and Marge talk with zookeeper Kenton Kerns about what led to this violent succession drama, the stress he feels in witnessing his first naked mole rat war and how he hopes it will resolve.

NOTE: This episode contains some detailed descriptions of animals fighting each other, so be warned.
