Once the stocks of larger species were depleted, orcas were targeted by commercial whalers in the mid-20th century. Between 1954 and 1997, Japan took 1,178 orcas (although the Ministry of the Environment claims that there had been domestic catches of about 1,600 whales between late 1940s to 1960s [214]) and Norway took 987. [215]
The fish that were offered were much smaller than the southern resident orca's normal prey. When one-pound fish were lowered into the water, the juvenile orca ignored them and inadvertently knocked them off the lines with his tail as he continued swimming around the pen, oblivious to the fact that they were meant to be food for him.

Moby Doll, who in 1964 in British Columbia became the second ever captive orca, was the first orca (killer whale) to be studied scientifically at close quarters alive.. Ken Balcomb, the founder of the Center for Whale Research, became one of the main researchers on Moby Doll's population, the southern resident orcas.
An orca pod in the Pacific Ocean off the coast of Mexico has devised a cunning strategy to hunt and kill whale sharks — the world’s largest fish that can grow up to 18 meters (60 feet) in ...
Type D or Sub-Antarctic [4] orcas were first identified based on photographs of a 1955 mass stranding in New Zealand and six at-sea sightings since 2004. The first video record of this type was made in 2014 between the Kerguelen and Crozet Islands, [61] and again in 2017 off the coast of Cape Horn, Chile. [62]
Orca show at SeaWorld San Diego. Orcas, or killer whales, are large predatory cetaceans that were first captured live and displayed in exhibitions in the 1960s. They soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size. [1]
In May, SeaWorld launched a new aquatic life park in the United Arab Emirates, its first outside the U.S., with no orcas. (The park features other animals, like dolphins and seals.) (The park ...
Belugas were the first whales to be kept in captivity. Other species were too rare, too shy, or too big. The first beluga was shown at Barnum's Museum in New York City in 1861. [140] For most of the 20th century, Canada was the predominant source of wild belugas. [141]
