Umm, a little stingray fact here...
...clipping of the stinger on a ray is not abuse, the barb is made of similar material to our fingernails and much like our fingernails when clipped causes no distress to the animal and will grow back.
Not that I'm defending the ray encloser at all, I've always felt that a natural enounter with sealife if much more satisfying than a captive one, and if I never get to dive with "such-and-such" animal in it's natural habitat, then that's the way it was ment to be.
And as a good friend on the board has pointed out, ray is just a fish, a cousin to the shark actually, if you have enjoyed scallops in restaurants on a regular basis, chances are you have eaten ray once or twice, as they are used for scallop subsitute on occation.
The place people should be up in arms about is the dolphin experience closer to town, in April they had no less than 5, and as many as 7 animals in an enclosure that wasn't big enough for one of the mammals.
