In the video, we see a turtle and a crab inside a glass tank. The turtle is swimming around the tank, while the crab is crawling on the bottom. The turtle has a brown shell with yellow and orange patterns, and the crab is grey with black spots. The tank is filled with water, and there is a white foam pad at the bottom. The lighting in the tank is bright, and we can see the reflection of the turtle and the crab on the glass.
