1. Fur: Sea otters have the densest fur of any mammal. Their fur consists of two layers: a dense underfur that provides insulation and a longer, waterproof outer fur. The fur helps keep them warm in cold waters and also aids in buoyancy.
2. Snout: Sea otters have a short, blunt snout with sensitive whiskers. These whiskers, called vibrissae, help them navigate and detect prey in murky waters.
3. Eyes: Sea otters have large, black eyes that are well-adapted for vision both in and out of the water. They have a wide visual field and can see in low light conditions.
4. Ears: Their ears are small and rounded and can close tightly to prevent water from entering.
5. Limbs: Sea otters have short, powerful legs with webbed feet. The hind feet are larger than the front feet and help propel the animal through the water. The feet are also used to grasp and manipulate prey.
6. Tail: The tail of a sea otter is long, thick, and muscular. It serves several purposes, including balance, propulsion, and storage. The tail can be used to propel the animal through the water, aid in diving and surfacing, and store fat reserves.
7. Teeth: Sea otters have sharp, pointed teeth that are designed for catching and crushing shellfish. They also have molars for grinding food.
8. Cheek Pouches: Sea otters have large cheek pouches that are lined with fur and open near their mouths. The cheek pouches are used to store food while they are hunting or diving.
9. Dive Reflex: Sea otters have a specialized dive reflex that allows them to conserve oxygen while underwater. When they dive, their heart rate and breathing slow down, and their blood vessels constrict to conserve energy.
10. Claws: Sea otters have strong, sharp claws on each foot. These claws help them grip and handle slippery prey and also aid in climbing and walking on land.
These body parts, combined with their unique behaviors and adaptations, enable sea otters to survive and thrive in their marine environment.
