Tilikum was the largest orca in captivity, weighing 12,500 pounds and measuring over 22 feet in length.

Tilikum was captured near Iceland in November of 1983, over 30 years ago. At only 2 years old, when he was approximately 13 feet long, he was torn away from his family and ocean home. Over the course of the years at SeaWorld, where he was confined to a tank containing 0.0001 percent of the quantity of water that he would traverse in a single day in nature, Tilikum has been involved in multiple incidents of aggression. The stress of captivity drove Tilikum to exhibit abnormal repetitive behavior, including chewing on metal gates and the concrete sides of his tank—so much so that the most of his teeth are completely worn down. The stress of captivity also caused Tilikum to exhibit aggression toward humans, which has cost three lives. Seaworld is a disgusting place, and many people are boycotting it.

Rest In Peace Tilikum......
