When threatened, they curl up into a tight ball. Their sharp-edged scales protect them from attackers. Tree Pangolins spend most of their time high in the forest canopy, feeding from ant and termite nests. But unlike us, they give birth to tiny young that develop in a pouch outside their mother's belly. Animals that do this are known as marsupials.
Most marsupials are plant-eaters and many are nocturnal.
Possums move through forests under cover of darkness, traveling between feeding and resting sites. They have good senses of hearing and smell. Possums mark their areas with their urine and dung, and rub one another with scents from skin glands. Marsupial meat-eaters, such as the Tasmanian Devil and Australian Native Cat, have good sight, hearing, and smell. They are excellent hunters.
