Beavers have evolved remarkable adaptations for life in wetlands:
- Dentition: Large, chisel-like incisors that grow continuously and are covered in hard enamel, perfect for cutting wood and building dams and lodges.
- Webbed feet: Partially webbed hind feet act like paddles for efficient swimming and transporting materials.
- Flattened tail: Serves as a rudder, a prop when standing upright, and a warning signal when slapped on water.
- Dense fur: Water-resistant fur traps air for insulation and buoyancy in cold water.
- Nocturnal behavior: Most active at night, reducing predator encounters and conserving energy.
- Dam building: Creates ponds and wetlands that benefit many species and regulate water flow.
