* Terrestrial animals: This is the most scientifically accurate term, as it literally means "of or relating to the earth."
* Land animals: This is a common and simple term, but it doesn't encompass all land-dwelling creatures.
* Mammals: This is a specific category of animals that includes humans, dogs, cats, elephants, etc.
* Vertebrates: This category includes mammals, reptiles, amphibians, birds, and fish.
* Fauna: This term refers to all the animal life in a particular region.
Ultimately, the best term to use depends on the context of your conversation. If you're talking about all animals that live on land, "terrestrial animals" is the most accurate.
