What Is The Most Common Animal On Earth

A swarm of common starlings. Numbering over 310 one thousand thousand, this species contains at least as many individuals as the U.s. does humans.[1] [two]

This is a collection of lists of organisms by their population. While well-nigh 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 environmental and biogeography. Individuals are counted by census, as carried out for the piping plover;[3] [4] using the transect method, as washed for the mount plover;[five] and starting time in 2012 by satellite, with the emperor penguin existence first subject field counted in this mode.[6]

Number of species [edit]

More than than 99 percent of all species, amounting to over v billion species,[7] that ever lived on World are estimated to be extinct.[8] [ix] Estimates on the number of World's current species range from 10 million to 14 meg,[10] of which nearly 1.2 million take been documented and over 86 percent take not yet been described.[eleven] According to another study, the number of described species has been estimated at 1,899,587.[12] 2000–2009 saw approximately 17,000 species described per year.[12] The total number of undescribed organisms is unknown, simply marine microbial species alone could number 20,000,000.[12] For this reason, the number of quantified species volition always lag behind the number of described species, and species contained in these lists tend to exist on the K side of the r/1000 selection continuum. More than recently, in May 2016, scientists reported that 1 trillion species are estimated to exist on Earth currently with simply ane-thousandth of one per centum described.[13] The total number of related Deoxyribonucleic acid base pairs on Earth is estimated at five.0 10 1037 and weighs 50 billion tonnes.[fourteen] In comparison, the full mass of the biosphere has been estimated to be as much as 4 TtC (trillion [meg 1000000] tonnes of carbon).[15] In July 2016, scientists reported identifying a set up of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Globe.[16]

Microbes [edit]

It is estimated that the most numerous bacteria are of a species of the Pelagibacterales (or SAR11) clade, possibly Pelagibacter ubique, and the most numerous viruses are bacteriophages infecting these species.[17] Information technology is estimated that the oceans comprise about 2.iv × 1028 (24 billion billion billion) SAR11 cells.[18] 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".[xix]

      • The domesticated craven (Gallus gallus domesticus), a Galliform, has an estimated population of 23.seven billion,[20] which is higher than whatever other bird.[21]
    • Gaviiformes (loons or divers)
    • Gruiformes (cranes and relatives)

    • Strigiformes (owls)
    • Struthioniformes (ratites)
    • Tinamiformes (tinamous)
    • Trogoniformes (trogons and quetzals)

Reptiles (Reptilia) [edit]

Animal Population Notes
Chinese alligator 100–200[22] Only in the wild. Chinese alligators are quite prolific in captivity, with estimates of the total captive population at over 10,000 animals, mostly in the Anhui Research Centre of Chinese Alligator Reproduction and the Madras Crocodile Bank.
Komodo dragon four,000–v,000 Their populations are restricted to the islands of Gili Motang (100), Gili Dasami (100), Rinca (1,300), Komodo (1,700), and Flores (perhaps two,000).[23] However, in that location are concerns that there may before long exist just 350 breeding females.[24]

Fish (Osteichthyes, Chondrichthyes, and Agnatha) [edit]

At that place are an estimated 3,500,000,000,000 (three.5 trillion) fish in the ocean.[25]

Hexapoda [edit]

Insects (Insecta) [edit]

Contempo figures indicate that in that location are more than 1.4 billion insects for each homo on the planet.[26] An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans.[27] Ants take colonised almost every landmass on Earth. Their population is estimated as 1016–1017 (ten-100 quadrillion).[28]

Plantae [edit]

Trees [edit]

Co-ordinate to NASA in 2005, in that location were over 400 billion trees on our globe.[29] Even so, more recently, in 2015, using ameliorate methods, the global tree count has been estimated at about three trillion.[30] Other studies testify that the Amazonian woods lonely yields approximately 430 billion copse.[31] Extrapolations from information compiled over a period of 10 years propose that greater Amazonia, which includes the Amazon Basin and the Guiana Shield, harbors around 390 billion individual copse.[32]
