From CBC News:
An animal rights group says the killer whale at Marineland appears to be sick, but officials insist that Kiska, a mainstay of the Niagara Falls, Ont., water park for many years, is in good health.
Orca United recently sent CBC News photos which it says show signs of a troubling condition known as “peanut head” — an indentation near the blowhole that is a sign of severe weight loss.
CBC News was given access to the park and Kiska. Her trainers say she has “good girth” and eats between 40 and 55 kilograms of fish a day.
