In the English language, many animals have different names depending on whether they are male, female, young, domesticated, or in groups. The best-known source of many English words used for collective groupings of animals is The Book of Saint Albans , an essay on hunting published in 1486 and attributed to Juliana Berners . [1]
Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from 8.5 μm (0.00033 in) to 33.6 m (110 ft).
Animals (or Metazoa) are living creatures with many cells. Animals get their energy from other living things. Usually, they eat them or are parasites. Animals, plants, fungi, and some other living things have complex cells, so they are grouped together as eukaryotes. The study of animals is called zoology.

Unlike other vertebrates, they are the only animals that produce milk for their young through their mammary glands. Parental care of the young is universal among mammals ...
Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular, [4] which separates them from bacteria and most protists. They are heterotrophic, [5] generally digesting food in an internal chamber, which separates them from plants and algae. [6]
