description Tammar wallaby Overview
The tammar wallaby is a small macropod species found in western and southern Australia, including on Kangaroo Island and some offshore islands. It is among the smaller members of the wallaby family. The tammar wallaby has been extensively studied as a model organism in marsupial biology, particularly for research on reproduction and development. Its genome was sequenced in 2011, contributing to comparative genomic studies between marsupials and other mammals.
The species is nocturnal and herbivorous.
help Tammar wallaby FAQ
Why is the tammar wallaby important to reproductive research?
The species can pause embryo development through embryonic diapause and later resume pregnancy in response to reproductive and seasonal signals. It has therefore become a valuable model for studying marsupial gestation, lactation, and developmental timing.
Where do tammar wallabies live in the wild?
Tammar wallabies are native to southern and western Australia, including several offshore islands. Their surviving populations include animals on Kangaroo Island and islands off Western Australia, although local histories differ because of introductions and extinctions.
What did sequencing the tammar wallaby genome reveal?
The genome published in 2011 gave researchers a major reference for comparing marsupials with placental mammals. It supported work on reproductive biology, immune development, sex chromosomes, and the evolution of mammalian genomes.
How does a tammar wallaby differ from a kangaroo?
It is a much smaller macropod with a compact body suited to moving through dense vegetation rather than the open-country scale of a red kangaroo. Both belong to the kangaroo family, Macropodidae, and both use powerful hind limbs for hopping.
