Bandicoots and Bilbies
Order Peramelemorphia
This small order of mammals consists of
some lesser known marsupials -- the bandicoots and bilbies, which are
native to New Guinea and Australia.
Peramelemorphs have long, pointed heads and
stout bodies. The hindelimbs are longer than the forelimbs and enable the
bandicoot or bilby to hop. Peramelemorphs are easily recognizable in that
their 2nd and 3rd toes on the forefeet are fused together, with just the
fingernails there to tell them apart.
Peramelemorphs have 7-8 polyprotodont
incisors. Dasyuromorphia is also polyprotodont, but can be distinguished
in that their incisors are pointed; bandicoot incisors are flattened.
Bandicoots and bilbies both have pouches (marsupiums)
which face to the rear and contain the nipples.
Peramelemorphs are terrestrial mammals and
feed on insects, rodents, lizards, and plants. There are 21 species,
divided into 2 families based on their geographic location (New Guinea or
Australia):
..Peramelidae
(bandicoots, bilbies) 10 spp — 2 extinct
..Peroryctidae
(spiny bandicoots, giant bandicoots, mouse bandicoots) 11 spp
Old System
..Peramelidae
(bandicoots, spiny bandicoots, etc)
..Thylacomyidae
(bilbies)
