Natural history
editThis genus contains a number of species with different habits making generalisation difficult. The overall body size varies widely, ranging from 60 to 160 mm. The tail is 60–180 mm and the weight is recorded from 12 to 90 g. They inhabit a wide variety of habitats from rainforests to plains and grasslands. The animals are nocturnal and spend the day in burrows. Food also varies with some species eating seeds, roots and insects while others feed primarily on grasses. The pebble-mound mice are unique in creating mounds of stones around their burrows. Several species of Pseudomys are threatened due to competition with introduced species and habitat destruction. Several others are probably extinct.
Etymology
editThe name Pseudomys means "false mouse"[1] presumably in reference to both its similarity and uniqueness from "true mice" in the genus Mus.
