Which of the following animals exhibits territoriality?

The animal that exhibits territoriality is the lizard. Territoriality is a behavior exhibited by many animals in which an individual or group of individuals defends a specific area, or territory, from others of the same species. In lizards, this behavior is often related to the need to establish a breeding territory or to protect limited resources such as food, water, or shelter. Lizards may display a variety of behaviors to defend their territory, including aggressive displays, vocalizations, and physical combat. The other animals listed (rabbit, earthworm, toad) may also have territories or defend resources, but they are not typically known for exhibiting territorial behavior to the same extent as lizards.
