Brasills

Brasills are a fictional species that appear in the speculative evolution project "Xenotheria". They are described as semi-aquatic, herbivorous mammals originating from a planet with a high concentration of methane in its atmosphere and a significantly larger moon than Earth. The Brasills are characterized by their robust, barrel-shaped bodies, short, powerful limbs, and broad, paddle-like feet. Their skin is thick and leathery, providing protection from the elements and potentially from predators. A distinctive feature is their large, bulbous snout, which is believed to house specialized olfactory organs adapted to detect food sources underwater and in the dense atmospheric conditions.

Their diet consists primarily of aquatic vegetation, which they gather using their prehensile lips. Brasills are social animals, living in small family groups that inhabit the marshy coastlines and shallow freshwater lakes of their homeworld. They are skilled swimmers, using their tails and webbed feet for propulsion and steering. Reproduction is ovoviviparous, with the young developing inside the mother before being born live. Their primary defense mechanism is their ability to submerge themselves quickly and remain underwater for extended periods. They are considered a relatively peaceful species, playing a crucial role in the ecosystem as grazers of aquatic plant life.
