Marine mammal park

A marine mammal park is a commercial theme park or aquarium. These venues keep marine mammals, such as dolphins, beluga whales, and sea lions, in water tanks.

Visitors come to watch special shows featuring these animals. These parks are more elaborate than a dolphinarium, which only focuses on dolphins. A marine mammal park functions as a combination of a public aquarium and an amusement park. It is important to distinguish these from marine parks. Marine parks often refer to natural reserves or wildlife sanctuaries, such as the coral reefs found in Australia.

The mechanism of these parks involves maintaining large, technical water environments. These pools require extraordinary financial and technical expenditure to operate. Many parks use these spaces for public education and scientific studies. To manage these complex systems, many parks joined the Alliance of Marine Mammal Parks and Aquariums. This international association was founded in 1987. It established offices near Washington, D.C., in 1992. The group works to ensure a high standard of care for the animals in their charge.

History shows how these attractions evolved over many decades. The first Sea Lion Park opened in 1895 at Coney Island in Brooklyn, New York. That park featured aquatic shows with 40 sea lions before it closed in 1903. In 1938, an oceanarium was established in St. Augustine, Florida. This location originally served as a large water tank for filming underwater movies. It later transitioned into a public attraction. Today, Marineland of Florida claims to be the world's first oceanarium. In November 1961, Marineland of the Pacific became the first park to display an orca in captivity. The orca, named Wanda, lived for only two days. Later, in 1964, the Vancouver Aquarium held an orca named Moby Doll for three months.

Between the 1970s and the 1990s, the industry changed significantly. Technical advances and public interest in aquatic life led to larger parks. These parks often feature cetaceans, which are a group of marine mammals including orcas and dolphins. During this time, SeaWorld USA emerged with many locations. They opened in Orlando, Florida, and San Diego, California. They also operated in San Antonio, Texas, and Aurora, Ohio. Today, many different types of parks exist globally. In Asia, there is Ocean Park in Hong Kong. In Europe, Loro Parque is located in Tenerife, Spain. North America hosts many locations, including the Delphinus parks in Mexico.

There is significant controversy regarding animal welfare in these parks. Groups like the WSPA consider keeping whales and dolphins in captivity to be a form of abuse. They argue that animals lack sufficient freedom of movement in artificial environments. For example, dolphins in the wild spend about 80% of their time deep underwater. They swim approximately 40 miles every day. In captivity, dolphins spend about 80% of their time above the water. They swim only a few miles per day. Studies show captive dolphins are six times more likely to die than those in the wild. They live an average of 40 years less than their wild counterparts.

Orcas face unique challenges in captivity as well. In the wild, orcas swim about 100 miles per day. They spend only about 10% of their lives at the ocean surface. In captivity, orcas cannot swim to their necessary depths. This lack of depth can cause sunburn and blisters. Extended exposure to open air can also cause the dorsal fin to collapse. As of 2016, 63 orcas were held in captivity in the United States. Many captive orcas die from disease, stress, or pregnancy rather than old age. One famous orca, Lolita, performed at the Miami Seaquarium for over 50 years. She was captured at four years old and died in the summer of 2023.

Legal protections have been created to address these issues. The U.S. Congress passed the Animal Welfare Act of 1966 to protect animals under human care. Later, President Richard Nixon signed the Marine Mammal Protection Act in 1972. This law prohibits the capture of marine mammals. These regulations connect the management of marine mammal parks to broader legal and ethical systems. The debate continues between those who value the educational mission of parks and those who advocate for total freedom for these complex animals.
