Slender animal about 90 cm high and which weighs from 40-65 kilos. It is yellowish at the front on top, darker at the back and white underneath. Only the males have horns, which can attain a length of 90 cm. The females live in groups which may hold up to 100 individuals, and it is in the breeding season when the males fight over a harem of several females for reproduction: although the males fight, it is unusual for them to be injured.
Originally from the south and east of the African continent, they establish themselves in forest margins and savannahs close to rivers because these are zones rich in nutrients, and therefore the vegetation is more nutritious than in other places. Impalas are always alert to possible predators. They have various signals for raising the alarm: lifting the tail, which is completely white underneath, while they leap around: in fact, they can leap up to three metres into the air and nine metres along the ground; they also warn using snorts which can be heard a long way off and they expel pheromones from the glands on their legs when they spot a predator. They live for around 15 years.
This is one of the most numerous antelopes of Africa and its populations are remaining stable at the moment.
