10 Animals That Came Back From Extinction
Takhi
It is known as true wild horse in the world they weigh around 300 kilograms. This species has 66 chromosomes as other common horses has 62 chromosomes. They originally lived in mongolian plains gradually moving to the gobi desert and they were last seen in 1969. They were believed to extinct due to loss of grassing land and hunting but thanks to ambitious breeding programmes that takhi’s are back.
Clarion Nightsnake
is a species of small colubrid snake endemic to clarion island initially described by a single specimen by william beebe in 1936. During the next several decades, scientists were unable to detect any trace of the snake in their field studies. After an intensive search in 2013, a team of scientists identified 11 snake that matched original description of the species. The snakes has the characteristics series of darker spots on their head and neck grows to be approximately 18 inches long. They usually lives on black lava rock habitat near the waters of sulphur gay.
Monito del Monte
one of the most impressive animal that came back from extinction, they are native only to southwestern south america, lives in the dense, humid forests of highland argentina and chile mainly in trees. The animal covers its nest with moss for concealment and for insulation and protection from bad whether. They are slightly bigger then common mouse and it uses appendages and free handed tail to climb.
Coelacarth
constitute a now rare order of fish that includes two extent species in the genus. They were long lived fish believed to extinct. In 1938 it has discovered in columinal river in south africa proved that coelacarth came back from extinction, this lives in water of the deep 100 meter below the surface.
Takahe
is a flightless bird indigenous to new zealand and belonging to the rail family. It was thought to be extinct after the last four known specimens were taken in 1898. However, after a carefully planned search effort the bird was rediscovered by geoffrey orbell near Lake Te Anau in the Murchison Mountains, South Island, on 20 November 1948.
Bermuda Petrel
Commonly known in Bermuda as the cahow, a name derived from its eerie cries, this nocturnal ground-nesting seabird is the national bird of Bermuda and can be found on Bermudan money. It is the second rarest seabird on the planet and a symbol of hope for nature conservation. They are known for their medium-sized body and long wings. The Bermuda petrel has a greyish-black crown and collar, dark grey upper-wings and tail, white upper-tail coverts and white under-wings edged with black, and the underparts are completely white. For 330 years, it was thought to be extinct. The dramatic rediscovery in 1951 of eighteen nesting pairs made this a “Lazarus species”, that is, a species found to be alive after having been considered extinct. This has inspired a book and two documentary films. A national programme to preserve the bird and restore the species has helped increase its numbers, but scientists are still working to enlarge its nesting habitat on the restored Nonsuch Island.
Pygmy tarsier
also known as the mountain tarsier is a nocturnal primate found in central Sulawesi, Indonesia, in an area with lower vegetative species diversity than the lowland tropical forests. The pygmy tarsier was believed to have become extinct in the early 20th century. Then, in 2000, Indonesian scientists accidentally killed one while trapping rats. The first pygmy tarsiers seen alive since the 1920s were found by a research team led by Dr. Sharon Gursky and Ph.D. student Nanda Grow from Texas A&M University on Mount Rore Katimbo in Lore Lindu National Park in August 2008. The two males and single female (a fourth escaped) were captured using nets, and were radio collared to track their movements. As the first live pygmy tarsiers seen in 80-plus years, these captures dispelled the belief among some primatologists that the species was extinct.
Loatian Rock Rat
is a rodent species of the Khammouan region of Laos. The species was first described in a 2005 article by Paulina Jenkins and coauthors, who considered the animal to be so distinct from all living rodents, they placed it in a new family, Laonastidae. It is in the monotypic genus Laonastes. . The discovery of the Laotian rock rat means an 11 million-year gap exists in the fossil record where no diatomyids have been found.
Cuban Solenodon
Since its discovery in 1861 by the German naturalist Wilhelm Peters, only 36 had ever been caught. By 1970, some thought the Cuban solenodon had become extinct, since no specimens had been found since 1890. This species of animals are polygamist which means they only meet up to mate and the male mates with multiple females. The males and females are not found together unless they are mating. The pair will meet up, mate, then separate. The males do not partake in raising any of the young.
The Caledonian Crested Gecko
This species was thought extinct until it was rediscovered in 1994.Along with several Rhacodactylus species, it is being considered for protected status by the Convention on the International Trade in Endangered Species of Wild Flora and Fauna. It is popular in the pet trade. The crested gecko has many naturally occurring color groups, some of which include: grey, brown, red, orange, and yellow of various shades. They have variable markings, which include spots, straight stripes, and tiger-like stripes. The colors are brighter and more prominent at night.The crested gecko has distinct structural morphs in head size and crest abundance. Geckos with a head length less than 1.3 times its width are considered “crowned”. The numbers and sizes of crests can vary; some geckos have crests that extend to the base of the tail and some lack crests on one side of their body.
