Question

How long do blue whales live for?

Answer 1

Blue whales have a life expectancy of 35-40 years, but the normal, un-hunted lifespan of a blue whale is estimated to be 80 years.Some can live up to 110 years in captivity.

Blue whales have a life expectancy of 35-40 years. However, there are many factors that limit the life span of the Blue whale. Packs of killer whales (orcas) have been known to attack and kill young blue whales or calves. Man also hunted blue whales until the International Whaling Commission declared them to be a protected species in 1966 because of a huge decrease in their population.

The Blue whale was too swift and powerful for the 19th century whalers to hunt, but with the arrival of harpoon canons, they became a much sought after species for their large amounts of blubber. They were also hunted years ago for their baleen, which was used to make brushes and corsets. But it was their size and high yield of oil that made them the target of choice for modern commercial whalers. Before mans intervention there were 228,000 Blue whales swimming the oceans of the world. ^Between 1904 and 1978, whalers scoured the seas for this huge cetacean, most were taken in the Southern Hemisphere, many illegally^ (Satchell 1998). As the population figure suggests, it was relentlessly slaughtered for every reason imaginable, almost to the point of extinction.

Another reason why Blue whales are almost extinct is pollution. Mosst of their illnesses are contracted by pollution.

It is estimated that there are about 10,000-14,000 blue whales world-wide. Blue whales are an endangered species. They have been protected worldwide by international law, since 1967. The blue whale was listed as endangered throughout its range on June 2, 1970 under Section 7 of the Endangered Species Conservation Act of 1969. They are not to be hunted by anyone for any reason at all. Suggestions are that some populations may never recover.

Conclusion Although Blue whales are now protected, we still must not hunt or kill them in their delicate balance of life. Some people believe that whales and dolphins are animal of mystery and beauty, and that a dead whale is an omen, good or bad. Most people say that all humans must protect all whales. We need to save these great water giants.

Good ;uck. Blue whaes are cooooooooool!
