The long-nosed bandicoot lives by itself, often chasing away other bandicoots. Their breeding season depends on the region in which they live. The female gives birth to two or three young after a short gestation period of 12 days. The tiny babies, blind and hairless, about 13mm in length, then move to the pouch where they are able to drink milk from the females eight nipples. They leave the pouch at about 54 days. The female is then ready to breed again. they live for between three and five years.
