The Detroit Zoo is mourning the loss of a female polar bear cub that died less than two days after being born.

According to the zoo, the cub was moved to an intensive care nursery on Thursday after video surveillance showed the cub had stopped nursing.

“We are all obviously grieving at the moment,” said Detroit Zoological Society Executive Director and CEO Ron Kagan.

Kagan said the staff did everything possible to save the cub, including around-the-clock shifts, pushing fluids, antibiotics and infusions of polar bear blood plasma.

“The veterinarians were ultimately able to raise the cub’s low body temperature, and attempted to compensate for very low blood sugar from the outset,” Kagan said.

The cub was born Wednesday to parents 6-year-old Suka, a first-time mother, and 14-year-old Nuka.

Suka arrived at the Detroit Zoo in 2018 to be paired with Nuka, who arrived at the Zoo in 2011.

A necropsy will be performed.
