视频展示了一只乌贼在水中的场景。这只乌贼的身体呈现出深紫色，头部有一双大大的眼睛，身体周围有八条触手。它的身体在水中微微摆动，触手也在轻轻晃动。背景是模糊的蓝色和绿色，可能是水下的植物或其他海洋生物。整个画面给人一种宁静而神秘的感觉。
The video shows a cuttlefish swimming gracefully in an aquarium. The cuttlefish has a dark, almost black body with a slightly lighter underside and is surrounded by a blue, underwater environment. Its tentacles are extended and moving fluidly as it navigates through the water. The background features blurred green aquatic plants, adding to the serene underwater atmosphere. The cuttlefish's large, round eyes are prominent, giving it an alert and curious appearance.
A squid is seen floating in a blue underwater environment with greenish vertical streaks in the background. The squid's body is mostly stationary, but its tentacles are slightly moving. The squid's right fin begins to rhythmically flap, creating a subtle motion. The flapping of the right fin continues consistently, while the rest of the squid remains relatively still.
