Concerns remain about the health of the Vancouver Aquarium's beluga whale Aurora after her health appeared to take a turn for the worse. The facility says in a news release that Aurora showed signs of improvement over the weekend but it appears her abdominal discomfort increased Sunday night. The whale's 21-year-old calf Qila had the same symptoms and died last week, leaving Aurora as the aquarium's lone beluga. The aquarium's head veterinarian Dr. Martin Haulena has adjusted Aurora's treatment, but is increasingly concerned about her health. Lab tests have been sent to veterinary experts around the world and a marine mammal team is monitoring the animal around the clock.
