Vancouver aquarium expecting another baby beluga

Staff at the Vancouver aquarium just might be humming the children's song Baby Beluga following word that 12-year-old beluga Qila is expecting a calf.

Qila became the first beluga conceived and born at a Canadian aquarium when Aurora delivered her in July 1995.

If the pregnancy goes as planned, Aurora who still shares the Arctic Canada exhibit with her daughter will become a grandmother in July or August.

As for the dad, it must be 19-year-old Imaq, the only male currently in the exhibit.

In July 2005, Qila's younger three-year-oldbrotherTuvaq died suddenlyin the pool.
