Scientists estimate that blue whales can live for at least 80 years, but since individual records do not date back into the whaling era, this will not be known with certainty for many years. The longest recorded study of a single individual is 34 years, in the north-east Pacific

Blue whales can live for 80 to 90 years. No blue whales are being killed now. Hunting of the blue whale stopped in 1977. Now, the blue whale's only predator is the orca, or killer whale (actually a type of dolphin). Almost a quarter of blue whales have scars from orca attacks, but the blue whale's size (up to 120 tonnes and 60 metres [200 ft] long, bigger than any of the dinosaurs) suggests they are difficult to kill. There is no information on how many are killed by orcas.
