Mental Health Issues

Captivity can trigger mental health issues in orca whales. Firstly, orcas can become stressed from confinement and tight spaces, and they can develop performance anxiety from frequent training and performances. Also, many whales have been kidnapped from their pods at a young age, which can be traumatic. For example, Tilikum was captured off the coast of Iceland at the age of 2 and taken from his family. This has led to mental instability in Tilikum and aggression. Tilikum is responsible for the deaths of SeaWorld trainer, Dawn Brancheau, and Keltie Byrne, a trainer at another marine mammal park called Sealand. Despite his history of aggression, SeaWorld continues to breed Tilikum with other whales and allow him to perform for the purpose of making money. Other whales have shown signs of aggression towards humans, and over 100 incidents have occurred. In the wild, incidents of aggression towards humans are extremely rare. Additionally, orca whales can be placed to live with orcas from other populations who do not speak the same language. Orca whales value social situations greatly, and if they are unhappy with their social situation, it can increase mental health issues. In fact, orca whales have a part of brain that humans don’t have called the paralimbic cleft, which processes social situations. Captivity can greatly affect the mental stability of orca whales.

Physical Health Issues

Orca whales suffer from physical health damage from captivity at SeaWorld. The average lifespan of an orca whale in the wild 30-50 years. At SeaWorld, the median life span is 9 years. Also, all of the adult males at SeaWorld have a collapsed dorsal fins. SeaWorld has claimed that collapsed dorsal fins are a common condition, using the results from a study of 30 wild orcas in New Zealand. Based on the data, it was determined that 23% of the New Zealand whales had a collapsed dorsal fin. However, 30 whales is a very small sample size, and other studies have found that less than one percent of orca whales in the wild have collapsed dorsal fins. Collapsed dorsal fins can be a result of the conditions in captivity, such as changes in hydration due to varying diets and lower blood pressure due to reduced physical activity. In captivity, because of stress, boredom, and anxiety, orcas often chew on the metal gates of their tanks. As a result, the orca's teeth may break, and their teeth are often treated without anesthesia.

Living Conditions for Orca Whales


Normally, in the wild, orca whales swim 100 miles a day in the ocean. In SeaWorld parks, orca whales would have to swim the circumference of their tanks 1,900 times to swim the same distance. Often, in the small confined tanks, fights occur between the whales. The fights are a result of the stress and anxiety that orcas endure from captivity and crowded tanks. However, when orca fights do take place, orcas do not have the ability to swim away to prevent injury or death as they would in the vast, wide open ocean. An example of a fight between two orca whales occurred at the SeaWorld park in San Diego, California, when a whale named Kandu V, attempted to “rake” a new orca whale recently placed in her tank. Raking is the forceful scratching of the dominant killer whale’s teeth against the other whale. However, Kandu V missed, and because of the small tank, she swam into the wall and ruptured an artery in her jaw. Unfortunately, the injury was fatal. The small tanks can cause aggression and lead to serious injury or even death.

Orcas also have an unnatural diet in captivity. Because the orca whales cannot hunt and obtain water from the bodies of their prey in captivity, they are fed gelatin, a protein obtained by boiling pig or cow bones, in order to stay hydrated. In addition, in captivity, orca whales are bred unnaturally. In the wild, orcas have the ability to choose who they mate with and when they mate. At SeaWorld, whales breed regularly without the choice of a mate. The male orcas are trained to lie on their backs, so the trainers can collect their sperm. The female whales are then impregnated, most often at an early age. For example, a whale named Katina was bred at the age of 9, when in the wild she would have bred at the age of 14. In many instances, the young females have been unfit to raise their calves, and many calves have died not long after their births.

SeaWorld: Beneath the Surface

SeaWorld. You can hear the shrieks of joy and laughter as a several ton whale jumps into the air. But what you don’t hear, is the shrieks of the poor orca whales trapped inside the confines of a small tank. SeaWorld: Beneath the Surface will expose all of the horrors of captivity at SeaWorld, that may be unknown to the public.
