species is sexually dimorphic, with females the larger of the
two sexes. Head and body length range from 70 to 85mm. Tail
length is 88 to 100mm. A male of head and body length 78mm weighed
13 grams and a female of 81mm weighed 17 grams.
This tiny, agile possum is one of the smallest known. It has
a long, pointed snout with abundant whiskers, and a long prehensile
tail. The soft padded toes have sharp claws, which enable T.
rostratus to grip both bark and glossy leaves equally well.
distribution of Tarsipes rostratus is restricted to the
sandplain heathlands, shrublands, and open low woodlands with
heath understory that patchily surround Australia's arid center.
The biology of this animal is linked to the distribution and
flowering patterns of nectar producing flowers, and flowering
plant species-richness is directly related to numbers of Tarsipes
lives in small groups, hunting for food, feeding on pollen,
nectar, and insects. It explores flowers thoroughly with its
long snout in search of its prefered foods, which include pollen
and nectar from Banksia, bottlebrushes, hakeas, dandras, Ti,
and eucalypt. It
gathers it with its 2.5cm bristled tongue, scraping it onto
its upper canines and lower incisors.
