How Many Animal Species Are There? Of all invertebrates, the insects are by far the most numerous. There are so many species of insects that scientists have yet to discover them all, let alone name or count them. Estimates of the total number of insect fall in the range of 1 to 30 million. The vertebrates represent the remaining 3% of all species and include species that are the most familiar to us: amphibians, reptiles, birds, fishes, mammals. The list below provides estimates of the number of species within various groups of animals.

Number of Species Identified on Earth The greatest species diversity exists among insects, which account for about one million of the earth's species known to science. Mammals make up one of the smallest groups, with just 5,513 members. Altogether the earth's oceans, lakes, continents and islands support over 66,000 identified species of vertebrate animals and more than 307,000 species of plants. The species totals do not include domestic animals such as sheep, goats and camels. Nor do they include single-celled organisms such as bacteria.
