Numbats
One of the most attractive of all
Australian animals is the numbat, a marsupial about
the size of a squirrel. It has a long, flattened
snout, head and body. Numbats have reddish-brown,
black-tipped fur with white stripes on the back.
Numbats have a dark stripe around their eyes that
looks like a burglar's mask. They measure about 45
centimetres, including their bushy brownish-grey
tails which stand up in the air. Their head and
body are about 25cm and their tails are about 18cm.
Numbats have four claws on each of their small
front and long back feet. Numbats move their back
feet together and then lean forward to move their
front paws together. If they move in a hurry they
make a series of leaps. Numbats are very light.
They only weigh 500 to 600 grams.

The numbat is an exclusively Australian marsupial
that has no close relatives anywhere. The numbat has two
other names: the walpuri and the banded anteater. Numbats
once lived in the southern part of Australia, but since
European settlement it has disappeared from almost all of
its former home and now lives in a few scattered places in
far south-western Australia. The numbat is very rare and on
the brink of extinction (there are only 2000 left). What's
even worse is that in the past few years the decline in
numbers has accelerated. Death by foxes, drought, or
frequent bushfires are all possible, how to prevent them are
still uncertain. To try and stop this people are breeding
numbats in captivity and releasing them into national parks
and in places where they were once common. The numbats that
are still alive live in eucalypt forests, especially wandoo
jarrah.
Numbats are unusual among Australian marsupial
in that they sleep by night and are active during the day.
Numbats eat in the morning and late afternoon but,
especially on hot days, often rest in a hollow log, under
fallen timber, or some similar shady place during the heat
of the day. Numbats will also choose to sleep in the same
kind of place. The numbat is the only marsupial that eats
only insects - mostly ants and termites. An adult numbat
will eat about 20 000 insects every day and must spend most
of the daylight hours feeding. A numbat finds the insects by
smell, scrabbles away the soil with its sharp-clawed
forepaws, then uses its extremely long, sticky tongue (which
is about 14 cm) in a rapid flicking action to gobble the
insects from their homes. Though the numbat has teeth (very
small and poorly developed), these are not used in feeding,
instead the termites and ants are swallowed whole.
Surprisingly, they don't need to drink.
Very little is known of the numbat's social
and reproductive behaviour. Adults are apparently solitary
and non-territorial, coming together only to mate. Breeding
begins in December and the usual litter of three or four
young are born between January and March, but details are
sketchy. Unlike most marsupials, the female numbat has no
pouch. The youngsters (which are about one-centimetre-long)
use their jaws to clamp firmly to their mother's teats (of
which there are four) and their claws to hold onto her fur.
When they grow fur of their own, the mother transfers them
to a grass- and leaf-lined chamber at the end of a shallow
burrow, about one or two meters long, that she digs in the
soil. Here they are left for a time while she looks for
food, but as they develop further she carries them with her,
the babies clinging to her back. By the following October
they have been weaned and finally wander off, fully
independent, sometime during November or December.
