Although dolphins generally interact well with humans, some attacks have occurred, most of them resulting in small injuries. Orcas, the largest species of dolphin, have been involved in fatal attacks on humans in captivity. The record-holder of documented orca fatal attacks is a male named Tilikum, who lived at SeaWorld from 1992 until his death in 2017. Tilikum has played a role in the death of three people in three different incidents (1991, 1999 and 2010). Tilikum's behaviour sparked the production of the documentary "Blackfish", which focuses on the consequences of keeping orcas in captivity. There are documented incidents in the wild, too, but none of them fatal.
