Qila the beluga dies at Vancouver Aquarium

Qila the first beluga whale conceived and born in captivity at a Canadian aquarium has died at the age of21, the Vancouver Aquarium has confirmed.

The cause of death has not been determined and a necropsy was expected to take place on Wednesday.

"She was a delight for our team of staff and volunteers every single day always the first to give us a wink, a little tail flap or a head bob in the morning," said the aquarium in a press release.

Outlived by her mother

Qila was born on July 23, 1995 to Aurora, which at the age of 29, is the only remaining beluga at the aquarium.

She was also the first beluga born in a Canadian aquarium to give birth to a calf of her own. Tiqa was born in 2008 but died three years laterfrompneumonia.

Qila's mother Aurora was from the Western Hudson Bay population of beluga whales. The average lifespan of a beluga from this population is 15 yearsin the wild but some havebeen known tolive as long as 40 or 50 years, according to Fisheries and Oceans Canada.

The first beluga born in captivity in Canada was Tuaq, who was born in 1977, but conceived in the wild. Tuaq died four months later due to malnutrition and a bacterial infection.

He was the offspring of Kavna, who was pregnant when captured and taken to the aquarium, and an unknown wild beluga.
