Komodo rhino

The Komodo Rhino is an animal from the Fire Nation, bred both as beasts of burden and for their meat. Komodo Rhinos were first domesticated by the Fire Nation in the Pho Zel Dynasty.

Anatomy
Komodo Rhinos are covered in thick, gray skin, which serves as natural protection for their body. Three large, curved horns dominate their faces; two curving down from their forehead and one curving upward from their snout. The creature's mouth and jaw structure look somewhat reptilian, but the small ears on either side of its head are mammalian. Their torsos resemble that of a rhinoceros, but ends in a long, dinosaur-like tail. The rhinos' feet are short, muscular, and clawed.

Connection
The Komodo Rhino resembles both its namesakes, the large Komodo Dragon and the African rhinoceros. It also resembles the ceratopsid dinosaur Triceratops.

The Fire Nation use these creatures during war as cavalry mounts, or as beasts of burden , often decorating them in red. Komodo Rhinos have been seen in almost every military operation, such as the Siege of the North and the Invasion of the Fire Nation, although they are most specifically used by the Rough Rhinos. The animals are also used for their meat, often made into traditional Komodo Sausages. These spicy sausages are soaked in brine for weeks and stuffed with rice and a variety of spices. Because of their portability, they are frequently served at picnics and sporting events.

Trivia

 * The Komodo Rhinos shown in The Last Airbender film do not possess horns like their animated counterparts, and more likely carnivores rather than herbivores.
