Well I went to work Saturday and Sunday at the Dallas Zoo. My job was to work the Stingray Exhibit. This was such an awesome exhibit. I had to touch them and feed them that way I could help all the people who came thru to do the same thing. Now the ones at the Zoo have all been trimmed from their barnacles and can no longer sting anyone. They are slimey to the touch and feeding them is fun. you hold the food between your fingers with your hand out flat and they come along and suck the food from your hand.
