MARSUPIAL MOUSE
With their big ears, long noses,
and pointed tails, %f,10,h\marsupia%marsupial mice
certainly look like field mice--but
the animals are not related. Field
mice are %f,10,h\rodent%rodents. Marsupial mice are
marsupials, members of the same
%f,10,h\order%order that kangaroos, koalas, and
opossums belong to.
Marsupials give birth to tiny,
underdeveloped young. The %f,10,h\offsprin%offspring
usually crawl into a pouch on their
mother's belly soon after birth.
They stay there for several weeks,
%f,10,h\nurse%nursing and growing larger and
stronger. The narrow-footed
marsupial mouse, for example, has a
well-developed front-opening pouch.
The flat-skulled marsupial mouse
has a rear-opening pouch, which
helps protect the young as the
mother crawls through tight clumps
of grass.
Other marsupial mice, like the
broad-footed marsupial mouse, may
have no pouch at all--or just a
small flap of skin around the
nipples. Marsupial mice %f,10,g\breed%breed
several times a year. Females give
birth to up to 10 or 12 young in each
%f,10,g\litter%litter. After the %f,10,h\mating%mating_season, a
strange thing happens to all the
male broad-footed marsupial mice.
They die, probably as a result of
stress.
Marsupial mice are good %f,10,h\predator%predators,
eating live food such as insects,
grasshoppers, lizards, and even
small %f,10,h\mammal%mammals and birds. The
flat-skulled planigale is the
smallest marsupial in the world,
weighing only a tenth of an ounce (5
grams)! It feeds on small
grasshoppers bigger than it is.
