Some stingray adaptations include a flat body, the location of the mouth and strong senses. The flat body of the stingray allows it to swim on the ocean floor or bury itself in the sand where it lurks for food, which is why the mouth is conveniently located on the underside of the body.
Stingrays have adapted to the ocean by developing extremely strong senses, including smell, hearing, touch and sight. The eyes of the stingray are placed on the top of the body so that while it lies in wait for prey in the sand, it can still see above itself. The ears, also located on top of the head, are very tiny holes that house incredibly sensitive hairs. These hairs detect vibrations. The stingray relies almost entirely on its sense of smell to sniff out food.
The southern stingray has a unique sense of touch that feels changes in water pressure released by mussels and clams. It also has an electrosense that enables it to hunt by following the electrical fields released by other marine life. The southern stingray also has spiracles on top of its head that enables it to breathe while feeding or hiding in the sand.
