Planigales

Planigales are a genus of marsupials belonging to the family Dasyuridae, commonly known as ningauis. These small, carnivorous mammals are native to Australia. The genus currently contains three recognized species: Planigale macleay (Macleay's planigale), Planigale gilesi (Giles's planigale), and Planigale ingrami (common or long-tailed planigale). Planigales are characterized by their extremely flattened heads, which allow them to squeeze into narrow crevices and under bark to hunt for insects, spiders, and other small invertebrates. They are among the smallest of all living mammals. Their bodies are slender and agile, with long, thin tails that are typically longer than their bodies. They possess sharp claws for digging and capturing prey. Planigales are primarily nocturnal and inhabit a range of arid and semi-arid environments across Australia, including grasslands, woodlands, and spinifex country. Their flattened skulls are a defining feature, making them easily distinguishable from other dasyurids. They build nests in burrows or hollow logs, often lined with dry grass and leaves. Breeding occurs seasonally, and females typically give birth to small litters, which are carried in a pouch. Despite their small size, planigales play a role in controlling insect populations within their ecosystems.
