The video shows a group of large tortoises eating green leaves. The tortoises are mostly dark gray in color with some lighter spots on their shells. They are all gathered around a pile of leaves, and some are actively eating while others are resting. The leaves are bright green and appear to be fresh. The tortoises are of various sizes, but all are quite large. The environment around them is not clearly visible, but it seems to be an outdoor setting with natural light.
