Animal biology is the study of animals and their biology, including their anatomy, physiology, behavior, and ecology. This field of research encompasses a wide range of topics, such as evolution, genetics, reproduction, nutrition, and interactions with their environment. Scientists in this field may study a variety of animals, from insects and fish to mammals and birds, in order to better understand the diversity of life on Earth and the important roles that animals play in ecosystems. Research in animal biology can help to inform conservation efforts, improve animal welfare, and advance our understanding of the natural world.
