The keeping of orcas and dolphins in marine parks causes documented welfare problems including stereotypy, aggression, and dramatically shortened lifespan.
Cetaceans in marine parks live lives fundamentally incompatible with their ecological and social needs. Wide-ranging, deep-diving social animals confined to pools develop stereotypies and pathological behaviors with no analog in wild populations. The evidence for suffering is unambiguous and has driven declining public acceptance of cetacean display worldwide.
