Females reach sexual maturity … Tammar Wallaby *threatened (macropus eugenii) The kangaroo… seasonal change in testicular or epididymal size and males are potentially fertile year-round (Inns, 1982). Like kangaroos, wallabies are marsupials that are part of the family Macropodidae. In the tammar wallaby, plasma testosterone and luteinising hormone (LH) also increase during the breeding season Long thought to be the only living member of the Wallabia genus, the swamp wallaby (Wallabia bicolor) is different from all the other wallabies because of its unique teeth and chromosome number – while other wallabies have 16 chromosomes, swamp wallaby males have ended up with 11 chromosomes, and the females have 10. Habitat The preferred habitat of the Swamp Wallaby is thick forest undergrowth or sandstone heath. Like the Black or Swamp Wallaby (Wallabia bicolour) pictured here. The kangaroo has more height between its ankles and knees, which makes its legs seem out of proportion to its body. Apparently, these mammals are most frequently seen swimming at dusk. Size The length of the Swamp Wallaby is between 66 - 85 centimetres. As a rule, the kangaroo is generally much larger than the wallaby. Home range size and resource selection by the swamp wallaby, Wallabia bicolor , in a landscape modified by timber harvesting Julian Di Stefano Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy March 2007 Department of Zoology and School of Forest and Ecosystem Science The University of Melbourne They have powerful hind legs they use to bound along at high speeds and jump great distances. The Red-Necked Wallaby (known as Bennett’s Wallaby in Tasmania) is found in a range of habitats along the eastern coast of Queensland, NSW, Victoria and Tasmania. The swamp wallaby, Wallabia bicolor, is a medium to large sized solitary macropodid (males: 17 kg, females: 13 kg). The males range in size from 15 to 27kg and females from 11 to 16kg. The swamp wallaby comes out at night to feed on pasture, shrubs, food plants, and agricultural crops. However, in both these species, prostate weights decline outside the breeding season (Merchant & Calaby, 1981; Inns, 1982). But most reports associated with kangaroos and wallabies swimming habits are anecdotal and more rigourous research is yet to be conducted. It was very fortunate to have two joeys so close in size to pair up and the two have really taken to each other. The main distinction between wallabies and kangaroos is based primarily on kangaroos being significantly larger than most wallabies. Wallaroo is a common name for several species of moderately large macropods, intermediate in size between the kangaroos and the wallabies.The word "wallaroo" is from the Dharug walaru.In general, a large, slim-bodied macropod of the open plains is called a "kangaroo"; a small to medium-sized one, particularly if it is relatively thick-set, is a "wallaby". While swamp wallaby lives alone it can also live in small groups during feeding. They are usually solitary but may be seen in groups when grazing. The first week of October, a month after getting Merlin into my care, Olly another swamp wallaby joey, only 50 grams heavier that Merlin, came into care after being rescued from the pouch of another motor vehicle victim. Native to Australia and Papua New Guinea, wallabies have been introduced to other areas of the world, including New Zealand and the United Kingdom. The adults reach the body length of 70 – 76 cm. Wallabies are typically small to medium-sized mammals, but the largest can reach 6 feet from head to tail. It has tail that is equal to the size of its entire body.
