RIP Oscar

Kamogawa Sea World in Japan announced today that Oscar died on the December 20th to an illness he had been fighting since December 14th. Kamogawa Sea World says that Oscar had been sluggish and had a loss of appetite since December 14th and was being given treatment by the trainers and vets. However, at about 6:15pm on December 20th, Oscar finally passed away. Kamogawa Sea World doesn't yet know what illness claimed Oscar's life as this is still currently under investigation. Here is the information written on their website, translated badly from Japanese:

Sorry that makes little sense. Oscar was the father of two calves, Earth, who was born in 2008, and Luna, who was born in July this year. Both of these young killer whales will now have to grow up without a father. Kamogawa Sea World's breeding program and shows have also been affected by Oscar's death. The killer whale exhibit is currently closed, with all the shows cancelled. Here is what Kamogawa Sea World say on their website, again translated badly from Japanese:
