- Koalas: Eucalyptus trees are the primary food source for koalas, which are iconic Australian marsupials. Koalas have specialized digestive systems that allow them to process the tough eucalyptus leaves.
- Insects: Eucalyptus trees are home to a diverse array of insects, including beetles, bugs, moths, and butterflies. Many of these insects feed on the leaves, flowers, or bark of the tree, while others use it as a shelter or breeding site.
- Birds: Eucalyptus trees provide habitat and nesting sites for various bird species, including parrots, cockatoos, honeyeaters, and kookaburras. These birds feed on the nectar, fruits, and insects found in the tree.
- Possums: Possums, which are small, nocturnal marsupials, are also common inhabitants of eucalyptus trees. They feed on leaves, fruits, and insects and use the tree's branches and hollows for shelter and nesting.
- Reptiles: Some species of reptiles, such as lizards and snakes, can also be found in eucalyptus trees. They use the tree for various purposes, including basking in the sun, finding food, and escaping from predators.
The specific types of living things found in a eucalyptus tree can vary depending on the location, climate, and specific species of eucalyptus tree.
