Despite successful rescue operation of the baby beluga whale from Alaska's Bristol Bay region, veterans and biologists fail to save its life.

The rescue operation was held in mid-June when the officials recovered a male baby, only few days old from the waters near the village of Naknek. Understanding the sensitivity of the case, the baby beluga was flown to the SeaLife Center on June 18 for better health care services.

But since Sunday, it was showing no improvements in its health rather it started signs of deteriorating health and finally succumbed shortly after midnight at the Alaska SeaLife Center.

Reports of its death came from a press release from the center. The rescue operation was the first such successful U. S. rescue of a stranded, live beluga calf that occurred since enactment of the Marine Mammal Protection Act in
1972.

Though the whale was under a perfect watch of several biologists and experts from around the world were observing the mammal digitally, it died and we have now lost it.

"It was really a day-by-day sort of thing. There were some days where he was better, but there wasn’t an overall trend until yesterday", said Ms. Tara Riemer Jones, President and CEO of the Alaska SeaLife Center.
