The following tags are used to highlight each species' status on the respective IUCN Red List published by the International Union for Conservation of Nature: Rodents make up the largest order of mammals, with over 40% of mammalian species.
The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas).
They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.
The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight.
