Semi-aquatic describes an organism or object that spends a significant portion of its life or time in or near water, but is not fully adapted to an aquatic environment. This can involve activities like foraging, nesting, or seeking refuge in water, while also spending time on land. These creatures possess a combination of terrestrial and aquatic adaptations, such as webbed feet, waterproof fur, or specialized respiratory systems. The degree of aquatic dependency can vary significantly, influencing their physical and behavioral characteristics. They are often found near bodies of freshwater or coastal areas.
