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 and invertebrates.
Amphibians are cold-blooded with a backbone and moist skin, however, unlike reptiles, they lack scales. The name amphibian means double life describing how these animals start their life in water and then undergo metamorphosis to live on land. Unable to regulate their heat, amphibians depend on warmth from the sun to become active.
