Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular,   unlike bacteria, which are prokaryoticand unlike protistswhich are eukaryotic but unicellular. Unlike plants and algaewhich produce their own nutrients  animals are heterotrophic  feeding on organic material and digesting it internally.
The blastula is a stage in embryonic development that is unique to most animals,  allowing cells to be differentiated into specialised tissues and organs.
Structure All animals are composed of cells, surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified, forming structures such as shellsbonesand spicules.
Typically, there is also an internal digestive chamber with either one opening as in flatworms or two openings as in deuterostomes. Nearly all animals make use of some form of sexual reproduction.
In sponges, blastula larvae swim to a new location, attach to the seabed, and develop into a new sponge. This may take place through fragmentation ; buddingsuch as in Hydra and other cnidarians ; or parthenogenesiswhere fertile eggs are produced without matingsuch as in aphids.
Animals are categorised into ecological groups depending on how they obtain or consume organic material, including carnivoresherbivoresomnivoresdetritivores and parasites. In carnivorous or omnivorous species, predation is a consumer-resource interaction where a predator feeds on another organism called its prey.
Herbivores eat plant material directly, while carnivores, and other animals on higher trophic levelstypically acquire energy in the form of reduced carbon by eating other animals.
