Conservation Once commercially hunted, the blue whale's numbers were greatly reduced during the first half of the 20th century. In the 1930-31 whaling season alone, more than 29,000 blue whales were killed worldwide. The species has been protected from commercial whaling since the mid-1960s. However, the population of blue whales is still small, estimated to be only several thousand. The major threats against blue whales in the 21st century are getting hit by boats and being trapped in commercial nets. Water pollution and climate change, both of which may reduce the number of krill, are other concerns. The International Union for Conservation of Nature (IUCN) continues to list the blue whale as an endangered species. Only a few thousand blue whales are believed to swim the world's oceans. They were hunted for many years for their blubber and oil, and they were almost hunted to extinction. They were protected under the 1966 International Whaling Convention and are now considered to be an endangered species. Fun Fact: A blue whale's heart is the size of a small car
