It's the end of an era for Miami Seaquarium, closing for good Sunday after more than seven decades on Virginia Key. The new developer is planning on relocating the dolphins, sea lions and other mammals there, but former animal trainer Valerie Warren has started a online petition to try and stop that from happening. Since Monday, the petition has received two-thousand signatures. The bankrupt theme park is being sold for 22 million to a local development firm planning on keeping the Seaquarium name and opening a new aquarium.
