Green slope behind the road. Martyshkino Konstantin Andreevich Somov (1869-1939)

The picture has something of this: water, underwater, fish, invertebrate, nature, sea, ocean, kelp, lake, wildlife, swimming, biology, medicine, pool, river, reproduction, landscape.
Perhaps it’s a painting of a landscape with trees and a body of water in the foreground, and a hill in the distance, with a blue sky in the background.
