Roan antelope
Roan antelope are found in woodland and grassland savanna, mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understorey (such as central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat midlength grasses. They form harem groups of five to 15 animals with a dominant male. Roan antelope commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.
Tibetan antelope
The Tibetan antelope is the sole species in the genus Pantholops, named after the Greek for "all antelope". It was formerly classified in the Antilopinae subfamily, but morphological and molecular evidence led to it being placed in its own subfamily, Pantholopinae, closely allied to goat-antelopes of the subfamily Caprinae. However, this has been disputed, and some authors consider the Tibetan antelope to be a true member of the Caprinae.
