Wombats are stout, sturdy marsupials. They grow to about 1.3 metres in length, and can weigh up to 36 kg. They have a large, blunt head with small eyes and ears, and a short, muscular neck. Their sharp claws and stubby, powerful legs make them great diggers. Wombats have been known to live for up to 27 years in captivity.
