All captive adult male orcas have collapsed dorsal fins, likely because they have no space in which to swim freely and are fed an unnatural diet of thawed dead fish. SeaWorld claims that this condition is common—however, in the wild, it rarely ever happens and is a sign of an injured or unhealthy orca.
