Cownose Rays are "moderately sized stingray native to the western Atlantic Ocean," according to Oceana.org. They are named as such "for their distinctly creased head lobes that resemble the nose of a cow." Being active swimmers, they can reach depths up tp 72 feet (or 22 meters). Currently, "experts consider this species ‘near threatened’ with extinction."
Although this marine species have poisonous stingers, they do "pose a minimal risk to humans stepping on their spine," as said by Oceana.org.
