More Information
Loons are adapted for aquatic life, with features like solid bones to reduce buoyancy and powerful webbed feet for propulsion. These adaptations make them excellent divers.
Tips
A common mistake is assuming that lightweight bones help with an aquatic lifestyle, but solid bones are actually what aid in diving by reducing buoyancy.
