The video shows a close-up of a large squid swimming in the ocean. The squid has a long, thin body with a large head and tentacles that are covered in small suckers. The squid's skin is a dark purple color, and it has a long, thin tail that it uses to propel itself through the water. The squid's tentacles are moving in a fluid, wave-like motion, and it appears to be swimming at a steady pace. The background is a deep blue color, indicating that the video was likely taken in the open ocean. There are no other visible creatures or objects in the video.
