In science, one of the most famous members of the Cypriniformes is the zebrafish (Danio rerio). The zebrafish is one of the most important vertebrate model organisms in biological and biochemical sciences, being used in many kinds of experiments. During early development, the zebrafish has a nearly transparent body, so it is ideal for studying ...
Tuatara, along with other now-extinct members of the order Rhynchocephalia, belong to the superorder Lepidosauria, as do the order Squamata, which includes lizards and snakes. Squamates and tuatara both show caudal autotomy (loss of the tail-tip when threatened), and have transverse cloacal slits.
The quagga was the first extinct animal to have its DNA analysed, [17] and this 1984 study launched the field of ancient DNA analysis. It confirmed that the quagga was more closely related to zebras than to horses, [ 18 ] with the quagga and mountain zebra ( Equus zebra ) sharing an ancestor 3–4 million years ago. [ 17 ]
The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow family of the order Cypriniformes.Native to South Asia, [2] it is a popular aquarium fish, frequently sold under the trade name zebra danio [3] (and thus often called a "tropical fish" although it is both tropical and subtropical).
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 65 extinct fish species, 87 possibly extinct fish species, and six extinct in the wild fish species. [ 1 ] [ 2 ] Cartilaginous fish
The quagga was probably vulnerable to extinction due to its restricted range, and because they were easy to find in large groups. The last known wild quagga died in 1878. [ 113 ] The last captive quagga, a female in Amsterdam's Natura Artis Magistra zoo, lived there from 9 May 1867 until it died on 12 August 1883. [ 114 ]
