It is hard to guess what a Blue whale weights. But we have the answer:
An adult Blue whale (Balaenoptera musculus) on average weights 154160.65 kg (339865.66 lbs).
The Blue whale is from the family Balaenopteridae (genus: Balaenoptera). It is usually born with about 2739.31 kg (6039.13 lbs). They can live for up to 110 years. When reaching adult age, they grow up to 30.48 meter (100′ 0″). Usually, Blue whales have 1 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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).
