Lists of organisms by population

This is a collection of lists of organisms by their population. While most of the numbers are estimates, they have been made by the experts in their fields. Species population is a science falling under the purview of population biogeography. Individuals are counted by census. More than 99 percent of all species, amounting to over five billion species, that lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. According to another study, the number of described species has been estimated at 1,899,587. 2000–2009 saw 17,000 species described per year. The total number of undescribed organisms is unknown, but marine microbial species alone could number 20,000,000; the number of quantified species will ipso facto always lag behind the number of described species, species contained in these lists tend to be on the K side of the r/K selection continuum.

More in May 2016, scientists reported that 1 trillion species are estimated to be on Earth with only one-thousandth of one percent described. The total number of related DNA base pairs on Earth is estimated at 5.0 x 1037 and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor of all organisms living on Earth, it is estimated that the most numerous bacteria are of a species of the Pelagibacterales clade Pelagibacter ubique, the most numerous viruses are bacteriophages infecting these species. It is estimated; the Deep Carbon Observatory has been exploring living forms in the interior of the Earth. "Life in deep Earth totals 15 to 23 billion tons of carbon". Mammals by population Artiodactyla Carnivora Cetacea Chiroptera Perissodactyla Primates Birds by population Anseriformes Apodiformes Caprimulgiformes Charadriiformes Ciconiiformes Columbiformes Coraciiformes Cuculiformes Falconiformes Galliformes The domesticated chicken, a Galliform, has an estimated population of 23.7 billion, higher than any other bird.

Gaviiformes Gruiformes Passeriformes Pelecaniformes Phoenicopteriformes Piciformes Podicipediformes Procellariiformes Psittaciformes Sphenisciformes Strigiformes Struthioniformes Tinamiformes Trogoniformes There are an estimated 3,500,000,000,000 fish in the ocean. In the last 100 years, the number of small fish – such as pilchards, anchovies and sardines – has more than doubled, it is caused by a major decline in big ‘predator fish’ such as sharks and cod due to over-fishing. Recent figures indicate. An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. Ants have colonised every landmass on Earth, their population is estimated as 1016–1017. According to NASA in 2005, there were over 400 billion trees on our globe. However, more in 2015, using better methods, the global tree count has been estimated at about 3 trillion. Other studies show that the Amazonian forest alone yields 430 billion trees. Extrapolations from data compiled over a period of 10 years suggest that greater Amazonia, which includes the Amazon Basin and the Guiana Shield, harbors around 390 billion individual trees
