Sad News from the Calgary Zoo

This is quite sad indeed. It will be interesting however to find out what could cause such a catastrophic event, there is a possibility that it was something from someone hands but i really have no idea what could possibly even deal such damage. Im leaning towards deliberate sabotage too but what was used is really the question.

I think that someone's hands would need to be covered in weapons-grade plutonium to cause such a severe reaction. No, if I can put my hands into my tank on accident after applying hand cream (oops!...only once...or twice....), I think the huge water volume of the stingray tank could withstand it.

It could even be something like...the grass outside the building was sprayed with fertilizer or weed killer. Who knows, right?

Either way, it's a great shame. I loved seeing the little beauties glide gracefully through the water, and they surely didn't deserve this.

FYI the hand cream reference was just an example...I'm not saying hand cream could do it, I'm just saying that its very plausible that it could have been something that got into the tank, and isn't something they can or do routinely test for.
