Water Lilies, Reflections of Weeping Willows (right half) Claude Oscar Monet (1840-1926)

The picture has something of this: fish, underwater, ocean, water, sea, invertebrate, seafood, crustacean, aquatic, shellfish, environment, marine, nature, wildlife, aquarium, tropical, swimming, coral.
Perhaps it’s a painting of water lilies in a pond with lily pads in the foreground and a background of other.
