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.

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.
The availability, for the first time, of an orca that could be studied at close quarters alive initiated pioneering research. From a recording of Moby Doll's calls, he was years later identified as a member of J Pod of the southern resident orcas. At the time of his capture, orcas were widely feared and hated.
The traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, [9] was that whales were related to the mesonychians, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates). This hypothesis was proposed due to ...
Here they were found by the heavily armed flagship of the London whaling fleet; a two-hour battle ensued, resulting in defeat for the Hull and York fleet and their expulsion from Spitsbergen. [46] In 1630 both the ships of Hull and Great Yarmouth, who had recently joined the trade, were driven away clean (empty) by the ships from London. From ...
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]
Beluga whales were the first whales to be kept in captivity. Other species were too rare, too shy or too big. The first was shown at Barnum's Museum in New York City in 1861. [111] For most of the 20th century, Canada was the predominant source. [112]
