There are three people visible in the image. They appear to be underwater, as indicated by the sandy bottom and the presence of underwater plants. The person on the left is wearing a dark-colored shirt and appears to be standing still. The person in the middle is also wearing a dark shirt and is holding what looks like a small object, possibly a piece of equipment or a tool. The person on the right is wearing a light-colored shirt and is also holding something similar to the other two. All three individuals seem to be engaged in some activity, possibly related to their underwater exploration.
