Semiaquatic

The Semiaquatic Rodentia, represented by the Beaver and Capybara subraces, embody the harmonious relationship between land and water, thriving in the lush ecosystems of rivers, lakes, and marshlands. Standing at a robust 5 feet tall with stout, burly bodies, they are the largest members of the Rodentia race.
  Both the Beaver and Capybara exhibit highly social behavior, forming tight-knit communities and extended family groups that provide mutual support and protection. Their semiaquatic nature enables them to navigate waterways with unparalleled skill, making them the foremost swimmers of the Rodentia race.
  While sharing many similarities, the Beaver and Capybara subraces are distinguished by subtle yet significant differences:
 

Capybara:

Characterized by their gregarious disposition and lack of a tail, Capybaras are the epitome of sociability among the Rodentia. They thrive in large, interconnected communities, fostering bonds of camaraderie and cooperation with their fellow Capybaras.
 

Beaver:

With their strong, flat tails and ornery disposition, Beavers stand apart from their Capybara counterparts. While equally adept at navigating aquatic environments, Beavers are renowned for their industrious nature, often constructing elaborate dams and lodges to create habitats conducive to their needs.
  Despite their differing traits, both the Capybara and Beaver subraces embody the essence of adaptability and resilience, seamlessly transitioning between terrestrial and aquatic habitats with finesse and grace. Their presence serves as a testament to the enduring bond between the Rodentia race and the natural world, where harmony and balance reign supreme.

Semiaquatic

The largest of the Rodentia subraces, the Semiaquatic Beaver and Capybara each stand at 5 feet tall with a burly, stout body. They are both distinctly social species living in extended family groups or small communities. They are semiaquatic and the most accomplished swimmers of the race due to their webbed fingers.
The primary distinctions between the two types are tail and disposition. Capybara have no tail and a gregarious disposition. Beavers have a strong, flat tail and an ornery disposition.

Rodentia

The Rodentia race consists of some of the smallest members of Chordata's populations. While the subraces each have somewhat diverse appearances and characteristics, they all share a small stature and innate nimbleness of movement. Most are natural burrowers and/or climbers and are more agile than most other races. In addition, the Rodentia have keen senses, deep intuition, and a connection with nature that few other races can boast.
