Characteristics of Animalia KingdomIt's hard to imagine that a sponge attached to a rock and a lion are in the same kingdom, but they share certain characteristics that land them together. For instance, creatures in the Animalia Kingdom are: Multicellular, which means that they are made up of more than one cell. Some members of other kingdoms are just made up of one cell, like bacteria or amoeba. Heterotrophic, which means they have to get their own food. Plants are autotrophic because they make their own food through photosynthesis. Because they cannot make their own food, members of the Animalia Kingdom must ingest, or eat, other organisms. Eukaryotes: this is the type of cells animals have. Eukaryote cells are more complex than the simpler prokaryote cells found in bacteria.
