What is the scientific definition of an animal?
In the scientific world, the term animal (Kingdom Animalia) refers to a broad and incredibly diverse group of living organisms. All animals share several key characteristics that distinguish them from other forms of life, such as plants or fungi. Firstly, animals are multicellular, meaning their bodies are composed of many cells. They are also eukaryotes, which are organisms whose cells contain a nucleus and other specialized structures enclosed within membranes.
