For species lacking significant blubber, such as the sea otter, the solution lies in their fur. These creatures represent some of the most profound examples of evolutionary adaptation, rewiring their physiology and behavior to thrive in a dense, buoyant, and saline environment.

They can drastically reduce their heart rate, shunting blood away from non-essential organs and toward the brain and heart. Sirenians and Others: This category includes manatees and dugongs, which are closely related to elephants, as well as the marine otter and the polar bear, which are more recently adapted to marine life.
They also tolerate high levels of lactic acid and carbon dioxide, effectively turning their bodies into efficient, temporary anaerobic machines. To combat this lethal chill, marine mammals have developed extraordinary insulation strategies.
