The image is a close-up of a sea shell, specifically a conch shell. The shell is light pink in color and has a spiral-like shape with a pointed tip at the top. The outer edge of the shell is slightly curved and has small indentations in the center. The inside of the conch is visible, with a small opening at the bottom. The background is black, making the shell stand out. The image is labeled with the text "3 mm" on the right side.
