zoo A park where captive animals, often from all over the world, live and are exhibited to visitors is a zoo. The word zoo comes from "zoology," the science of animals.

zoology Anyone who likes to visit a zoo or an aquarium, who collects butterflies, or who enjoys fishing or hunting shows an interest in zoology. The word zoo is from the Greek word zoion, which means "animal." Zoology is the science of animals as botany is the science of plants. Together they make up biology, the science of all living things. Zoology involves determinations of the structure, function, and interspecific relationships between different animals. A primary goal of zoologists is to understand the origin and evolution of different species of animals. These include not only the obvious species, such as the vertebrates and large invertebrates, but also parasites and microscopic organisms.

Like other basic sciences zoology is subdivided into various specialized fields. Some fields focus on particular animal groups, such as icthyology (the study of fishes), ornithology (the study of birds), and entomology (the study of insects). Others examine certain aspects of how animals are structured, how they function, or how they are related to one another. These fields include genetics, anatomy, ecology, behavior, and many others. Evolutionary biology focuses on the determination of animal origins and relationships and thus encompasses all of the fields of zoology.
