Stingrays are very smooth and definitely feel like wet velvet. If you love stingrays, you need to visit Grand Cayman island and visit Stingray City out in the ocean. It's an area where stingrays congregate and they are so used to humans that you can feed them, pet them, etc. I actually floated in the ocean and had a stingray lay on top of me. It was amazing! We went as part of a cruise ship stop in the Caymans (although we went with a private company, not the cruise ship excursion, there were only 6 people in our group!!).
