They usually give birth to one young per cycle although twins have been reported. After this mating, a near term fetus is growing in one uterus while the new embryo is developing in a second. The suckling of the newborn temporarily halts the development of the second embryo which remains dormant until the first young is ready to leave the pouch. Swamp wallabies are strictly herbivorous.
