Life on Earth is certainly diverse; over 2 billion species have been identified. To help organize all this biological diversity, animals with similar characteristics are grouped into classes. At Sunset Zoo we exhibit several animal classes including: mammals, birds, fish, reptiles, amphibians, invertebrates.
All birds have a body covered in feathers and are considered warm-blooded vertebrates. These animals hatch from eggs, have two wings, and two feet, however, not all birds can fly.
