Less than a week after the Brookfield Zoo's new bottlenose dolphin was born, the calf has died.
The female calf, born at the Chicago-area zoo on August 2 to 26-year-old Allie, had not yet been named and was just announced to the public and introduced to the media on Wednesday.
The calf was initially healthy buts its health began to decline rapidly on Wednesday and she died Thursday morning, according to the Chicago Tribune. A necropsy will be performed to determine its cause of death and her mother Allie is being closely monitored.
Brookfield Zoo spokesman Bill Zeigler said the dolphin's passing "was devastating to everyone in our zoo family, but particularly to the dolphin staff," NBC Chicago reports.
