The swamp wallaby has long, coarse fur that is generally dark brown in color with darker or black limbs and tails. Food Habits Swamp wallabies are strictly herbivorous. Their diet consists of soft plants such as buds, ferns, leaves, shrubs, and grasses. They have been known to eat bark, shoots from needle-leaf trees, and plants that can be poisonous to domesticated animals. Reproduction Swamp wallabies, both male and female, attain sexual maturity at an age of 15 months and may live up to 15 years in the wild.
Females are polyestrous and are able to breed all year long.
They usually give birth to one young per cycle although twins have been reported. Following its birth, the young, normally weighing less than 1g, will spend the next 8-9 months in its mother's pouch. The gestation period is 33-38 days long while the estrous cycle is on average 34 days in length. This species is unique in that it is the only marsupial whose gestation period is longer than their estrous cycle. This means that females can mate during the last few days of their pregnancy allowing them continuous breeding and birthing approximately every 8 months.
