The most recent occurred in 2010, when Tilikum supposedly grabbed his trainer, Dawn Brancheau, by her hair and forcefully dragged her underwater. Tilikum, whose stage name is Shamu at SeaWorld Orlando, weighs approximately 12,000 pounds, and Dawn was one of their best and most experienced trainers. Tragically, Tilikum had also been involved in another earlier death of a trainer, in 1991, when Keltie Lee Byrne accidentally fell into the tank. A homicide investigation showed that Tilikum and two other orcas purposely prevented Byrne from getting out of the pool, causing her to drown. After Brancheau's death, Tilikum was prohibited from doing public appearances. However, just 13 months later, he re-joined the cast of Believe, SeaWorld's most popular dolphin and whale show. These are only some of the horrific incidents that can occur because of what these orcas face and live by. If you really wanted to help this issue then do not assist with the income of these companies, Instead of booking a day trip to SeaWorld or Marine World, go to an awesome amusement park, or go out on a boat to look for these animals out in their natural habitat and surroundings also sign petitions online and sign up to websites because every little thing counts towards raising awareness for these
