The common term for the scientific study of animals is zoology. This branch of biology focuses on understanding the behavior, physiology, evolution, and classification of animals. Zoologists may study various aspects of animal life, including anatomy, ecology, genetics, and interactions within ecosystems. The field is vast, encompassing everything from microscopic organisms to large mammals. Zoology also plays a crucial role in wildlife conservation, understanding species' dynamics, and preserving biodiversity. With the threats posed by habitat destruction and climate change, zoologists' work is vital for maintaining healthy ecosystems and ensuring the survival of various animal species.
