Somebody shoulda told all of this to Steevo!
Many moons ago I had one get me in the palm of my hand whilst unhooking it. The stinger broke off in my hand and I couldn't get it out due to the serrations on the barb. Had to get at doctor to cut it out.
I must say that was a truly stimulating experience! The mucus coating on the barb retards healing and I had a drippy hole in my hand for months.
And by the way, those round stingrays are delicious, especially breaded and deep fried.
You can always find them with the fish mongers on the Malecon. Just look for the stuff labeled "Scallop" or "Escalopa". They get a primo price for them as well!!
They punch out plugs of that tasty boneless white meat with a shotgun shell or cookie cutter, trim off the skin then "skin" the Gringos Estupidos.
