Chicago aquarium announces death of Marineland beluga Caspian

Another whale shipped out of the now defunct Marineland in Niagara Falls has died at the Shedd Aquarium in Chicago.

The aquarium says 27-year-old Caspian died on Wednesday, despite efforts to save her.

A cause of death has not been determined yet, but aquarium staff say she had not been eating properly, and blood samples showed abnormalities in her electrolyte levels.

Two other whales that died at the Chicago location had pre-existing diseases at the time of their deaths.

Four belugas and one dolphin have already died after the massive relocation from the shuttered theme park over the summer.

Shedd Aquarium recently released reports on the deaths of whales Peekachu, who died on Aug. 25, and Rain, who died on Sept. 2, which says both whales had significant, longstanding inflammation in their digestive systems.

A preliminary report says Osiris, a 26-year-old female beluga that died on Sept. 21, had chronic liver disease.

The aquarium says all six remaining rescued belugas are eating their full diets.
