A Tasmanian pygmy possum (Cercartetus lepidus) usually gives birth to around 3 babies.
Upon birth, they weight 1 grams (0 lbs) and measure 2.9 cm (0′ 2″). They are a member of the Burramyidae family (genus: Cercartetus). An adult Tasmanian pygmy possum grows up to a size of 8.8 cm (0′ 4″).

The Tasmanian pygmy possum (Cercartetus lepidus), also known as the little pygmy possum, is the world’s smallest possum. It was first described by Oldfield Thomas in 1888, after he identified that a museum specimen labelled as an eastern pygmy possum in fact represented a species then unknown to science. The holotype resides in the British Museum of Natural History.
