What is a trait possessed by the southern sea otter that helps it to catch prey?

The southern sea otter has a thick, dense fur that helps it to catch prey. Here's how:

* Buoyancy: The otter's fur traps a layer of air, making it extremely buoyant. This allows them to float effortlessly on the water's surface, giving them a better vantage point to spot prey.

* Warmth: The dense fur acts as excellent insulation, keeping the otter warm in the cold ocean waters. This allows them to stay submerged for longer periods, increasing their hunting time.

While other traits like their sharp claws, powerful jaws, and flexible bodies also aid in catching prey, the thick fur is crucial for providing the necessary buoyancy and warmth for successful hunting.
