视频中展示了两只水獭在清澈的蓝色水中游泳的场景。它们的身体大部分浸没在水中，只有头部和部分背部露出水面。水獭们似乎在悠闲地游动，水面泛起轻微的涟漪。阳光照射在水面上，使得整个画面显得非常明亮和生动。水獭们的毛发在水中显得光滑而湿润，显示出它们适应水生生活的特征。
The video shows two sea lions swimming in clear blue water. They are moving gracefully, with their bodies partially submerged and their heads occasionally breaking the surface. The water ripples around them as they swim, creating small waves and splashes. The scene is calm and serene, capturing the natural behavior of these marine mammals in their aquatic environment.
Two sea otters are floating on the surface of the water, moving slowly in a calm, blue environment. The otters occasionally adjust their positions, with one otter turning its head and the other moving its limbs. As they continue to float, one otter raises its head and brings its paw to its mouth, appearing to groom or inspect it. The other otter remains in a relaxed position, floating nearby.
