This photomicrograph shows the retina from the eye of a three-day-old zebrafish (Danio rerio). Zebrafish are small tropical freshwater fish that are widely used in scientific research. The retina is viewed here from the front, as if the viewer is looking directly into the eye of the fish. This image is of the whole eye, created by reflecting half the image across its origin to represent the naturally occurring perfect symmetry observed in the zebrafish.
