Victims of captivity at the hands of the Mirage Hotel. They may be gone, but they will never be forgotten.
Stereotypical Behaviors Displayed at the Mirage Dolphin Habitat
Stereotypical behavior, or abnormal behavior, in dolphins is a symptom of lack of stimulation and boredom. While in captivity, these dolphins are reduced to small barren tanks, kept away from certain members of the pod, and are told when to eat and exercise. The dolphins at the Mirage are no different. Only the main tank has a coral bottom, and to be honest, I never really see the dolphins interacting with it much. Even when they have their “enrichment toys”, you will find them waiting at the gate.
Displays of Aggression
Swimming in Circles
There’s an abundance of evidence that shows that dolphins and whales in captivity show a lot of the same abnormal behaviors that are exhibited by other animals in captivity. These include things like stereotypes where they do repeated movements, self mutilation and just basically other behaviors associated with being psychologically disturbed. There are also several peer-reviewed studies that have shown elevated stress hormones in dolphins and whales in captivity.
So there really is no way that an artificial setting could provide an opportunity for the range of natural behaviors that dolphins enjoy in the wild, just from a physical point of view. The largest tank in the world is something like less than one ten-thousandth of one percent of the natural range of most dolphins and whales. So there’s physically no way that these animals could exhibit natural behaviors in captivity.
I know that some members of the captivity industry have made the point that in captivity these animals are fed fish and they don’t need to deal with the stress of capturing their own prey. But in fact, being fed dead fish can be a stress. In the wild, they really enjoy the opportunity to collaborate with each other and catch prey and travel with their companions, and basically work for their prey. In captivity, all of that stimulation is taken away. – Dr Lori Marino
Poxvirus is a disease that forms skin lesions on dolphins. It has been observed in both free-ranging and captive bottlenose dolphins.The large patches are made up of smaller spots. The color and size can change rapidly. The disease occurs frequently in captive dolphins and is endemic in some colonies. Dolphinpox is not contagious to humans like the pinniped version of the disease. In captivity, there appears to be a correlation between pox-like lesions and stress, environmental conditions, and the overall health of the animal. Poxvirus is not immunosuppressive unlike the cetacean morbillivirus. Poxvirus could worsen due to water temperature and quality, salinity levels or periods of environmental, physical, and/or mental stress. Dolphins under natural conditions often tolerate salinity changes, yet in captivity they have been destroyed by the combined effects of an otherwise mild disease superimposed on a severe skin condition resulting from overly dilute water.
We have been reporting on Maverick’s condition with the poxvirus since January 2014. He has shown signs of the disease for a minimum of 2 years. The disease did not pop up in the Mirage habitat until just months after Seaworld Orlando shipped Beetle and Cosmo over. This according to photo evidence archived on Flickr. Orlando is still dealing with the poxvirus as shown in photos sent to me in August 2014. Update: As of January 2015, the Poxvirus at the Mirage is clearing up.
