Populations of humpback whales, Megaptera novaeangliae, and blue whales, Balaenoptera musculus, around South Georgia crashed around the time of World War 1, and further exploitation occurred in other regions into the 1930's.
Most of the animals had been either humpbacks, Megaptera novaeangliae, or blue whales, Balaenoptera musculus, two species that were officially considered "protected" under the international regulations that governed commercial whaling.
