The cutie from our Cute Otter Sticker is a semiaquatic mammal known for its playful behavior, streamlined body, and thick fur. These creatures can be found in many aquatic environments, including rivers, lakes, and coastal areas. Otters have long, sleek bodies that are adapted for swimming. They have webbed feet and strong tail that helps them maneuver in the water. Otters also have thick fur that traps air and keeps them warm in cold water.
