The scientific name Tapirus indicus was proposed by Anselme Gaëtan Desmarest in 1819 who referred to a tapir described by Pierre-Médard Diard. [2] Tapirus indicus brevetianus was coined by a Dutch zoologist in 1926 who described a black Malayan tapir from Sumatra that had been sent to Rotterdam Zoo in the early 1920s.
Tapir species, from top left clockwise: South American tapir (Tapirus terrestris), mountain tapir (Tapirus pinchaque), Malayan tapir (Tapirus indicus) and Baird's tapir (Tapirus bairdii)
Tapirus is a genus of tapir which contains the living tapir species. The Malayan tapir is usually included in Tapirus as well, although some authorities have moved it into its own genus, Acrocodia .
A germ layer is a primary layer of cells that forms during embryonic development. [1] The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans ( animals that are sister taxa to the sponges ) produce two or three primary germ layers.
The white rhinoceros is the largest living perissodactyl. Perissodactyla (/ p ə ˌ r ɪ s oʊ ˈ d æ k t ɪ l ə /, from Ancient Greek περισσός, perissós ' odd ' and δάκτυλος, dáktylos ' finger, toe ' [3]), or odd-toed ungulates, is an order of ungulates.

The blastoderm now consists of three layers, an outer ectoderm, a middle mesoderm, and an inner endoderm; each has distinctive characteristics and gives rise to certain tissues of the body. For many mammals, it is sometime during formation of the germ layers that implantation of the embryo in the uterus of the mother occurs. [18] [20]
A germ layer is a collection of cells, formed during animal and mammalian embryogenesis. Germ layers are typically pronounced within vertebrate organisms; however, animals or mammals more complex than sponges ( eumetazoans and agnotozoans ) produce two or three primary tissue layers.
