ONE GREEN PLANET - WHY WHALES AND DOLPHINS DO NOT BELONG IN TANKS
EXCERPT: Depression, aggression, poor dental health, self-mutilation, vomiting, suicide attempts, drugs, illnesses – don’t these all seem like signs ultimately leading to death? According to a research study conducted in 1995 by Robert Small and Douglas Demaster, the annual mortality rate for captive dolphins was two and a half times higher than that of wild cetaceans. Sadly, not much has changed since then for the benefit of captive cetaceans. While wild killer whales have been known to live as long as 80 to 90 years, only two female orcas in captivity have passed the age of 40, and no males have lived longer than 35.
