This is an image of the ventral (bottom) surface of an embryonic skate, Raja, a cartilaginous fish that is related to skates and stingrays. These animals have electroreceptor sensory organs that allow them to sense electric fields in the water. They use these fields to sense and avoid predators and as part of their mating strategy. This image was prepared at the 2011 Woods Hole Embryology Course.
