Fully grown, they reach 90 up to 130 cm and weigh between 22 and 40 kg. Wombats have a thick, broad head and a vestigial tail. The wombat's large head contains small eyes. Its eyesight is poor, while its senses of smell, hearing and sensing vibrations are well developed. Their dentition lacks tusks. Wombats are torpid and have a nesting pouch that, unlike kangaroos, opens backward - the young enter the pouch from the mother's rump. It protects the young from being buried in the ground when digging burrows. There are two nipples in the bag.
