Arsin

The Arsins are a family of herbivorous mammals belonging to the order Embrithopoda, which means that they're related to Afrotheres such as elephants, manatees, hyraxes, tenrecs, aardvarks, and kin. The Arsins were discovered by Derrel Summers, the younger brother of Peter Summers, and their are only two species native to the savannas of Gondwana.

Big Horned Arsin
The Big-Horned Arsin is a species of Arsin that is indigenous to Northern and Eastern Gondwana. Big-horned arsins normally live in small groups up to about 9 in an area. They are herbivores that mainly feed on grass, leaves, shrubs, roots, tubers, fruits, and vegetables. Unlike rhinos (in most species), the big-horned arsins aren't near-sighted so they could see whatever is dangerous and what isn't to reduce conflicts between sapient species/beings and these animals. They are normally found in many savannas and scrublands of Gondwana.

Tapir-Nosed Arsin
The Tapir-Nosed Arsin is a species of Arsin that is indigenous to some parts of Gondwana, mostly large lakes and rivers. They are named because of the tapir-like noses, something that their prehistoric Earth relatives, the Eocene Arsinotheres, and another species of arsin, the big-horned arsins, do not have. They have tapir-like noses to reach into underwater plants more efficiently. Like its relative, they are herbivores and mainly fed on not just underwater plants, but also grass, leaves, shrubs, fruits, and vegetables.
