Northern Brown Bandicoot - Life History

Life History

The northern brown bandicoot diligently marks and retains its territory. It has scent glands on the ears, mouth, pouch, and cloaca. This solitary marsupial is aggressive only towards others of its species. If a bandicoot is startled in its nesting site, it will flee. Hardly ever will the northern brown bandicoot defend itself unless two males confront one another over territorial rights. Then, either a male is killed or one male becomes subordinate to the other and avoids confrontation. The subordinate male also forfeits to the dominant male all sexual relations with local females. Bandicoots are not social animals and do not live in groups, with the exception of mother and her young.

The northern brown bandicoot breeds throughout the year. An average litter consists of 2 to 4 young. Being marsupials, the newborns are naked and immature and thus undergo extensive development within the mother's pouch. The gestation period (12.5 days) is the shortest recorded for any mammal. Bandicoots are also the only metatherian marsupials that have placentas similar to eutherian mammals. Juveniles are weaned at 60 days post partum. By this time, the marsupial young are capable of sustaining endothermy on their own. I. macrourus have a lifespan of approximately two years.

Female bandicoots produce between 8 and 11 litters in their lifetime. Male bandicoots don't play a significant role in the care of juvenile I. macrourus.

    ... there is no point in being realistic about here and now, no use at all not any, and so it is not the nineteenth but the twentieth century, there is no realism now, life is not real it is not earnest, it is strange which is an entirely different matter.
    Gertrude Stein (1874–1946)

    ... all big changes in human history have been arrived at slowly and through many compromises.
