Watch a stingray glide over the sandy sea floor and you can tell it’s in hunting mode – but the tricks the ray is using to search for prey may not be so obvious.

A stingray’s eyes are located on top of its wide, flat body, while its mouth is on the underside. This may not seem like the best design for a fish that has to scan the murky bottom for hidden clams and crustaceans. Luckily, rays are endowed with remarkable sensory abilities that make them ace hunters.
