Two dolphin calves die at zoo
A dolphin calf has died at Brookfield Zoo in Chicago, the second loss this month.
The calf died on Friday having been born just 7 days earlier to a 9-year-old bottlenose dolphin called Allison.
On December 5th, another dolphin, Noelani, gave birth but the calf died within a few minutes.
A necropsy (animal autopsy) will be carried out to try and determine the cause of the deaths.
