The welfare of captive whales and dolphins has become one of the most debated issues in animal welfare. Evidence increasingly shows that captivity cannot meet their complex needs.
Captive cetacean welfare represents one of the most clear-cut cases where the evidence strongly supports that the needs of the animals cannot be met in any current captive facility. Wild orcas travel 100+ miles daily in complex social groups spanning generations. The gap between this natural existence and a tank, regardless of its size, cannot be bridged. Dorsal fin collapse - absent in the wild but nearly universal in captive males - is a physical manifestation of chronic stress and unnatural conditions. The significantly shortened lifespans of captive orcas relative to wild counterparts is stark evidence of welfare failure. The acoustic disruption from tank walls affects animals that navigate and communicate through sophisticated echolocation. Public opinion has shifted dramatically on this issue, driving industry change.
