The Rhinoceros is a huntable animal introduced in Rise of the Rajas, and it is mostly found in maps set in South East Asia. A powerful animal, it will viciously defend itself against any attacker, but as it provides 400 food, it is one of the most valuable animal food sources in Age of Empires II.
It is worth noting that unlike other similarly aggressive huntable animals such as the Elephant or the Wild Boar, the Rhinoceros may often be found in packs, sometimes up to three.
The Rhinoceros is the second largest huntable animal in Age of Mythology, only beaten by the Elephant. It will not attack Villagers on sight, but will defend itself if attacked and a group of villagers will be needed to hunt them.
The Rhinoceros of Set is the largest animal that Pharaohs worshiping Set can train with a cost of some favor. They're available in the Mythic Age, and can cause great damage.
The Rhinoceros icon depicts a two-horned species similar to the African White Rhinoceros (Ceratotherium simum). However, the animal model in the game has only one horn and the skin fold "armor" typical of Asian rhinoceroses.
There are five living species of rhinoceros, three of which are native to Asia, and all of which are endangered. Although its massive body and extremely thick skin garner much attention, the rhinoceros is most commonly known for its horns, one or two depending on the species.
The rhinoceros horn is composed of the fibrous protein keratin, which makes up the skin cells, hair, scales, and feathers of many animals. Its huge frame is supported by short legs with broad feet, ending in three-toes. Along with the tapir and the horse, the rhinoceros makes up the order of odd-toed hoofed animals. It is an herbivore, a browser, or a grazer, depending on the particular species. During the day, a rhinoceros enjoys the shade, wallowing in the mud to stay cool in the blistering sun. They most often feed by night, or in the cool of the early morning.
Of the three Asian species of rhinoceros, two have a single horn. The Indian rhinoceros, or Rhinoceros unicornis, grazes on the grass of the plains of Nepal, Assam, and Bengal. It can reach weights of up to 2 tons, yet still achieve a running speed of 30 mph. The Indian rhinoceros has an armor-plated appearance due to the deep folds and creases in its fibrous skin. The Javan rhinoceros, or Rhinoceros sondaicus, is nearly extinct. The only two-horned Asian rhinoceros is the Sumatran species, or Dicerorhinus sumatrensis. Its hairy coat and small stature make the Sumatran rhino unique among the five species, for it only reaches a height of about 4.5 feet tall, and a weight of about 1 ton. It is highly endangered. Only a few hundred survive, inhabiting forests in Sumatra, the Malay Peninsula, and Borneo."
