This creature follows the traditional form of a beaver, but there the similarities end. Instead of fur, these creatures are covered in hard, bony plates.

The armor-plated beaver resembles nothing so much as a mixture of a sturgeon and a beaver. Their normal slick fur is replaced by thick bony plates, allowing them to build their lodges beneath pounding waterfalls and in raging currents. Their tails are quite strong, capable of pushing them against vastly stronger currents than their smaller cousins.

Like their cousins, they are generally herbivores but will defend their lodge from intruders to protect their young. The beavers live in family groups within the lodge, with an adult female and adult male in a monogamous pair, and their children, called kits. A kit does not grow its solid armor plating until it reaches its first year. Beyond the family unit, however, the beavers are fiercely territorial. An armor-plated beaver family unit marks its territory by building scent mounds.
