How Sea Otters intake Oxygen and let out CO2 -
Sea otters don't breathe under water. The only animals that can are ones that have gills. Sea otters can hold their breath for long periods of time but must come up eventually. When the sea otters come up to breathe their noses and eyes are up high to see better and breathe better. Sea otters may have a countercurrent heat exchange system. Arteries and veins in the extremities are very close together. Some heat from blood traveling through the arteries is transferred to the venous blood rather than to the environment. This system aids otters in conserving body heat.
