Banded Langur, a Southeast Asian monkey that has been considered a single species for more than 100 years, has actually been found to be classified into three different categories, according to a published journal in Scientific Reports. Because there was no easy-to-understand difference at first glance, it was not noticed up to now.
Since these monkeys are distributed across Myanmar, Thailand, Malaysia, Singapore, and Indonesia, conventional classifications did not believe that extinction was imminent. However, according to the new classification, two of the three species are in a fairly critical situation and require urgent protection.
It should be noted that the use of state-of-the-art gene sequencing tools. The researchers succeeded in correcting the classification using DNA collected from monkey feces. This technology, which does not damage animals, has the potential to be widely used in the field of science.
“We hope that this paper will lead more research on the diverse monkeys that inhabit Asia,” said Andy Ann, the paper’s lead author and researcher at the Singapore Conservation Fund for Wildlife Conservation.
“There must be more species than we know now. If we don’t know that, we’re in danger of being lost.”
In 19th-century records, the monkey, along with two other monkeys (Higasis Matra Banda Langur, Robinsons Banded Langur), was classified as a subspecies of Presbytis femoralis. It is natural to classify it so if it is the only appearance. All three variants have black body hair, and the white pattern of the face and belly is only slightly different.
It was not easy to confirm the authenticity of this intuition. Banded Langur is known as a monkey that is hard to see. They spend a few things, move quickly, and spend most of their time on trees. It is difficult to take a picture or take an arrow to collect a blood sample because it moves as soon as it is understood that man approaches. In the first place, the method of using arrows is fraught with the risk of stressing and injuring monkeys.
The new classification has raised the need for urgent protection for two of the three species, Raffles Banded Langur (Presbytis feralis) and The Giosbytis Percura . These species have a small population and a limited habitat, so they meet the conditions of “critical endangered”
