– South Central Black Rhino ( Diceros bicornis minor ): the most numerous of the four subspecies, they are found in South Africa, Zimbabwe, and southern Tanzania and have been re-released in Botswana, Malawi, Swaziland, and Zambia. Currently, the world has four subspecies: However, Africa’s conservation policies have doubled the number of black rhinos to nearly 6,000 to date. The period 1960-1995 marked the serious collapse of this rhino species when there were only about 2,500 individuals left. With a low and long-lasting reproductive capacity, the black rhino was subject to extinction at the hands of European hunters when they arrived on the Black Continent.

A female adult is pregnant for 15-16 months and usually gives birth to an individual every 2.5-3 years. In terms of lifespan, black rhinos can live from 35-50 years. However, the black rhino horn is larger than other types of rhino horn, with the front and rear horns measuring 130cm and 55cm respectively. Black rhinos are smaller than white rhinos, they are about 1.7m tall at shoulder height and weigh 1300kg. With a different diet, black rhinos can live with white rhinos, avoiding unnecessary conflicts. growing on it as high as leaves, branches, etc. Thanks to this feature, they can eat growing plants. The black rhinoceros ( Diceros bicornis ), also known as the hook-lipped rhinoceros, make the snout on the rhinoceros angular, elongated and forms a V.

Hopefully, the plan will be successful and we can see the Northern white rhinos walking in the future! According to LA Times, three embryos have been successfully created since January 2020 and are waiting to be implanted into a female of the Southern subspecies for surrogacy. However, scientists still did not give up and tried to save the future of the Northern white rhinoceros with artificial insemination (IVF) by combining eggs from a female with frozen sperm from the female. Northern white rhinoceros ( Ceratotherium simum cottoni ) – Conservation status: Critically Endangered (CRI): in contrast to the southern subspecies, this number is 2 for the northern subspecies!!! That’s right, the Northern rhino subspecies had only two females left, Najin (34 years old) and Fatu (23 years old) when the last male named Sudan died, causing the extinction of the subspecies.Africa South Africa, Namibia, Zimbabwe, Kenya. Southern white rhinoceros ( Ceratotherium simum simum ) – Conservation status: Vulnerable (according to IUCN): This is the predominant subspecies of the white rhino with more than 18,000 individuals distributed mostly in four countries.The white rhino has two subspecies, which are: In terms of longevity and reproduction, white rhinos can live from 35-40 years, females are pregnant for about 16 months.

Up to now, the world has recognized five distinct rhinoceros species roaming the African savannas and Asian forests: Genetic variation is the core factor that brings in biodiversity since it introduces diversity among species and subspecies. Despite differences, they contribute greatly to the sustainability of the ecosystem by interacting with each other in different ways such as mutualism, parasitism, hunting, etc. Biodiversity means the existence of various earthly life forms found in fauna, flora, and microorganisms. The annual May 22nd was chosen to celebrate International Biodiversity Day by U.N General Assembly in 2000 to raise awareness about the importance of biodiversity. Guess what! There is another upcoming day for animal lovers like us to join in and celebrate together, it is International Biodiversity Day! Greetings, Vietnam’s brave Rhino Heroes! After a great holiday celebrating Hung Kings’ Festival, Victory Day (30/4), and International Workers’ Day (1/5), it’s time for Vietnamese people to get back to schools, and workplaces.
