* Water-resistant fur or feathers: Bogs are also often cold and damp, so animals that live there need to be able to stay warm and dry. Water-resistant fur or feathers help animals do this.
* Ability to eat a variety of foods: Bogs are not always rich in food, so animals that live there need to be able to eat a variety of things. Many bog animals are omnivores, which means they eat both plants and animals.
* Ability to tolerate low oxygen levels: Bogs are often low in oxygen, so animals that live there need to be able to tolerate these conditions. Many bog animals have adaptations that help them breathe in low-oxygen environments, such as special gills or lungs.
