Calgary zoo rays die due to human error

[chevyjaxon]

you would think that the keepers would be passionate enough to do copious amounts of reading on the species they keep and just marine life in general the problem is most people today have a lack of passion for anything but miller time, so just keep flaming the zoo they deserve it for a boo boo that big but even more importantly did they never check their PH Im sure that would be the first indicator that something is amiss
