Molerats are the only social vertebrates known to man. This means that these mammals live in colonies similar to those of ants and termites, with a single fertile queen giving birth to nonreproductive workers and soldiers. Molerats are also famous for their incredibly powerful jaws, the muscles of which constitute 25% of their body mass. Baby molerats are raised on a diet of their older sibling's fecal pellets, emitting a special cry when hungry to summon a worker.
