The branch of science that focuses on the study of animals is called zoology. Zoologists explore various aspects of animal life, including their behavior, physiology, ecology, and evolution. This field encompasses a wide range of studies, from understanding animal anatomy to researching the relationships and interactions between different species in their environments. Zoologists may specialize further in various disciplines, such as entomology (study of insects) or ornithology (study of birds), contributing to our overall understanding of biodiversity and conservation efforts.
