这段视频展示了一种黄色和白色相间的海洋生物，可能是某种珊瑚或海鞘。它们附着在一根绳子上，背景是深色的海水。这些生物呈现出波浪状的纹理，颜色鲜艳，主要以黄色为主，带有白色的条纹。随着视频的进行，可以看到这些生物在轻微地摆动，显示出它们的生命力。周围的水中有细小的颗粒漂浮，增加了画面的动态感。
The video shows a close-up of a yellow and white sea squirt colony attached to a rope underwater. The sea squirts have a distinctive pattern with yellow stripes on a white background, and they appear to be swaying slightly in the water. The background is dark, suggesting that the scene is deep underwater. The sea squirts are densely packed together, forming a vibrant and intricate structure.
The video shows a vibrant yellow and white sea slug with intricate patterns on its body, moving in a dark underwater environment. The sea slug begins to contract its body, causing its tentacles to curl inward. As the contraction continues, the sea slug's body becomes more compact, and its tentacles are drawn closer together. The contraction progresses further, with the sea slug's body becoming even more tightly packed, and its tentacles almost fully retracted. The sea slug completes its contraction, with its body now significantly smaller and its tentacles fully curled inward.
