Blue whale size: How big do they get?

How big does a Blue whale get? Here is an overview over the average adult age:

A grown Blue whale (Balaenoptera musculus) reaches an average size of 30.48 meter (100′ 0″).

When born, they have an average size of 0 cm (0′ 0″). During their lifetime of about 110 years, they grow from 2739.31 kg (6039.13 lbs) to 154160.65 kg (339865.66 lbs). A Blue whale has 1 babies at once. The Blue whale (genus: Balaenoptera) is a member of the family Balaenopteridae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a Blue whale is (100' 0

The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whale suborder Mysticeti. Reaching a maximum confirmed length of 29.9 meters (98 feet) and weight of 173 tonnes (190 tons), it is the largest animal known to have ever existed. The blue whale’s long and slender body can be various shades of grayish-blue dorsally and somewhat lighter underneath.There are currently five subspecies of blue whale, recognized by the Society for Marine Mammalogy’s Committee on Taxonomy: B. m. musculus in the North Atlantic and North Pacific, B. m. intermedia in the Southern Ocean, B. m. brevicauda (the pygmy blue whale) in the Indian Ocean and South Pacific Ocean, B. m. indica in the Northern Indian Ocean, and B. m. unnamed subsp. in the waters off Chile. The blue whale diet consists almost exclusively of euphausiids (krill).Blue whales were abundant in nearly all the oceans on Earth until the end of the 19th century. They were hunted almost to extinction by whaling until the International Whaling Commission banned all hunting of blue whales in 1967. The International Whaling Commission catch database estimates that 382,595 blue whales were caught between 1868 and 1978. The global blue whale population abundance is estimated to be 10,000-25,000 blue whales, roughly 3-11% of the population size estimated in 1911. There remain only much smaller concentrations in the Eastern North Pacific (1,647), Central North Pacific (63-133), North Atlantic (1000-2,000), Antarctic (2,280), New Zealand (718), Northern Indian Ocean (270), and Chile (570-760).
