Abstract from DBPedia
    Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft). They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and the chordates, the latter including the vertebrates. Life forms interpreted as early animals were present in the Ediacaran biota of the late Precambrian. Many modern animal phyla became clearly established in the fossil record as marine species during the Cambrian explosion, which began around 539 million years ago. 6,331 groups of genes common to all living animals have been identified; these may have arisen from a single that lived 650 million years ago. Historically, Aristotle divided animals into those with blood and those without. Carl Linnaeus created the first hierarchical biological classification for animals in 1758 with his Systema Naturae, which Jean-Baptiste Lamarck expanded into 14 phyla by 1809. In 1874, Ernst Haeckel divided the animal kingdom into the multicellular Metazoa (now synonymous for Animalia) and the Protozoa, single-celled organisms no longer considered animals. In modern times, the biological classification of animals relies on advanced techniques, such as molecular phylogenetics, which are effective at demonstrating the evolutionary relationships between taxa. Humans make use of many animal species, such as for food (including meat, milk, and eggs), for materials (such as leather and wool), as pets, and as working animals including for transport. Dogs have been used in hunting, as have birds of prey, while many terrestrial and aquatic animals were hunted for sports. Nonhuman animals have appeared in art from the earliest times and are featured in mythology and religion.

    後生動物（こうせいどうぶつ、Metazoa）は、生物の分類群の1つで、真核生物のオピストコンタに属する。海綿動物、刺胞動物、左右相称動物などが含まれる。二界説での動物界から原生動物を除いたもの、五界説で動物界とされたものにほぼ等しい。

    動物（どうぶつ、羅: animalia、英: animal）は、 1. * 生物学における生物（特に真核生物）の分類群の一つ。かつて生物は、感覚と運動能力によって植物と動物に大別されていたが、動物はヘッケルにより多細胞性の後生動物と単細胞性の原生動物 に分けられた。ホイッタカーによる五界説ではこの後生動物のみを動物界 Animaliaとして扱い、これを「動物」として扱うことが一般的である。 2. * 日常語において、動物とは1. の意味の動物のうち、ヒト以外のもの。特に哺乳類に属する生物を指す事が多い。 本項では1. の意味を解説し、特に断りのない限り、後生動物を指すものとする。 動物を扱う学問を動物学といい、動物の生物学的側面に加え、動物と人とのかかわりが対象とされる。動物の研究史についてはこの「動物学」も参照。
