In the American zoo 54 stingray died

In the American zoo "Brookfield", which is located in Chicago, a tragedy occurred. There in the aquarium 54 skate died. Zoo experts have already figured out that this was due to a sharp drop in the level of oxygen in the water. The tragedy report appeared on the zoo's official Facebook page.

The veterinarians tried to provide emergency assistance to the skates, but failed to save them.

"We are devastated by the tragic death of these animals," said Bill Ziegler, senior vice president of the animal program at the Chicago Zoological Society, which oversees the zoo.
