视频中展示了一只海獭在水中游泳的场景。海獭的身体大部分浸没在水中，只有头部和部分背部露出水面。它在水中游动，时而浮出水面，时而潜入水下。水面波光粼粼，反射着阳光，显得非常明亮。海獭的动作灵活，似乎在享受游泳的乐趣。背景是广阔的水面，没有其他明显的物体或生物出现。
The video shows a sea otter swimming in a body of water. The otter is initially seen floating on its back, then it rolls over and swims forward. It continues to swim and occasionally surfaces, showing its head above the water. The water appears calm with gentle ripples. Another sea otter can be seen in the background, also swimming. The scene captures the natural behavior of the sea otters in their aquatic environment.
A sea lion is seen floating on the water's surface, moving steadily to the right. The sea lion continues to swim, gradually submerging its head and body into the water. As it dives, it raises its front flippers briefly before fully submerging. Another sea lion is visible in the background, also floating on the water's surface.
