Animals are multicellular, eukaryotic organisms that belong to the biological kingdom Animalia. They are characterized by their ability to move voluntarily, consume organic material, breathe oxygen, and reproduce sexually or asexually. Animals possess specialized sensory organs, nervous systems, and other complex structures that enable them to interact with their environment and other organisms. Unlike plants and fungi, animals lack cell walls and typically develop from a blastula during embryonic development.
