视频中展示了两只鲸鱼在海面上的尾鳍。画面左侧的鲸鱼尾鳍较小，正在缓缓地沉入水中，只露出一小部分在水面上。右侧的鲸鱼尾鳍较大，呈现出明显的V字形，尾鳍边缘有锯齿状的特征。随着视频的进行，右侧的鲸鱼尾鳍也逐渐下沉，最终消失在水面之下。背景是平静的海水，呈现出深蓝色调，波纹细腻。
The video captures two humpback whales in the ocean. The focus is on their large, distinctive tail flukes as they prepare to dive. The whale on the right raises its tail high out of the water, displaying the intricate patterns on its underside. The whale on the left also lifts its tail, though not as prominently. Both tails then submerge into the calm blue water, creating gentle ripples on the surface. The scene is serene, with the vast expanse of the ocean surrounding the whales.
In a calm, blue water setting, a whale's tail is seen emerging from the water, gradually descending as it moves deeper into the water. The tail continues to lower until it is almost fully submerged, with only a small part still visible above the water surface.
