caption: The image shows a close up of a daphnia, a small aquatic animal, under a microscope. It is zoomed in, allowing us to see the intricate details of its structure, such as its long, thin body, long antennae, and small, round head. Its eyes are large and round, and its mouth is slightly open, revealing its sharp teeth. Its body is covered in small bumps and ridges, giving it a wrinkled texture.
