The dunnart is a small marsupial native to Australia and New Guinea. It belongs to the family Sminthopsis and is known for its slender body, large ears, and long tail. Dunnarts are nocturnal and primarily insectivorous, feeding on insects and other small invertebrates. There are several species of dunnarts, each adapted to different habitats, including grasslands and woodlands. They are typically solitary animals and use burrows or leaf litter for shelter. Due to habitat loss and predation by introduced species, some dunnart populations are threatened, making conservation efforts important for their survival.
