Dibblers are also a species of broad footed marsupial mouse: Parantechinus apicalis. While not true mice, dibblers are similarly small and pointy-nosed, and also have a similar lifespan (two to three years). They live in dense grasslands and are mostly carnivorous, though they occasionally feed on nectar. Like many marsupials, they are nocturnal. They are distinguished from other marsupial mice by their spotted coats, which are brown with grey speckles.

Dibblers are very rare. Perhaps calling them endangered is an understatement: in 1884, they were declared extinct! Not a hint of them was seen again until 1967. Forty thousand nights have been logged trying to get an accurate feel for their numbers. A measly forty five dibblers have turned up.
