Rhinoceros

Rhinoceroses are one among the talking beasts that live in Narnia. They have been present since the dawn of Narnia's history, when Aslan sung them into existence.

Descriptions
Rhinoceroses are universally recognized by their massive bodies, stumpy legs and either one or two dermal horns. The rhinos seen in Narnia were grey coloured ones.

Bio
In 2005 film of the The Lion, the Witch and the Wardrobe, at least two Rhinos were part of Aslan's Army. One Rhino tried to help Oreius the centaur by charging at the White Witch, but it fell during his charge and may have been killed by the Ankle Slicers since he was not seen again. However, it's possible that Lucy may have used her cordial to save his life.

The other Rhino's fate is unknown, though chances are it survived due to Aslan arriving with reinforcements.
