There is also an antelope found only in Tsavo East and West, among the ten animal species at risk of extinction in the entire planet. 
This was revealed at the Italian National Conference for Biodiversity, held in Rome.
Based on a report by the Wildlife Conservation Society, we now know that Hunter's damalisk, an increasingly rare African antelope, is among the ten animals we must try to preserve from possible extinction. At one time this type of antelope, though coveted by Kenya's felines and carnivores, populated the entire area from Tsavo East National Park to the Somali border with thousands of specimens. The first censuses, from 1976 to 1978, were of 14.000 specimens, which decreased vertiginously to two thousand in 1995, due to the fact that its flesh became food for the populations more and more affected by hunger, especially in the areas of the Tana River and in the Somali region of the Juba, where they were used to migrate. The recent WCS report counted only 600 of them. This is why Kenya is now carrying out conservation projects, defending a small population of about 100 animals in Tsavo East. 
Keeping the Damaliscus company are the Angonoka tortoise of Madagascar (400 specimens), the green-eyed frog (4,000) in Panama and Costa Rica, the Sumatran orangutan, the Vietnamese presbyterian monkey, the Florida bat, the Gulf of California seal (known as the "vaquita") and the aurochion, a small Channel Island fox, also in California. In Kenya, the Grevy's Zebra, Rotschild's Giraffe and the now iconic Northern White Rhinoceros, which will breed through artificial insemination, are of note.
