This video features a group of animated purple whales swimming in the ocean. The whales are of different sizes, with the largest one leading the group and the smallest one following behind. They are all swimming in the same direction, with bubbles coming out of their mouths. The background is a deep blue color, representing the ocean, and there are some sandy areas with small rocks and plants visible at the bottom of the frame. The animation is smooth, and the whales move in a realistic manner.
