The blue whales have a wide distribution, found in the world’s oceans from the poles to the equator, exhibiting seasonal migrations from the polar and subarctic regions in summer to the tropical and subtropical waters in winter. Before whaling there may have been as many as 250,000; today, it is one of the world's rarest species, with the population of blue whales numbering just 10,000-25,000. They can weigh more than 180 metric tonnes (almost 400,000 lbs) and grow to 30 m (98 ft) long! Dany Zbinden of the organization Mériscope stresses the importance of protecting whales, as doing so will not only ensure the recovery of their own populations, but also the survival of other species in the marine ecosystem. While it may be considered an endangered species, the blue whale is truly international, occurring in all oceans except the Arctic, and enclosed seas of course. It weighs as much as 33 elephants, are as long about three school buses, has a heart the size of a Volkswagen Beetle, and it must eat around 4 tons of krill per day! era it is believed that whale hunting hadn’t caused much ecological impact due to limited technology and most killings remained limited to the coast line and near offshore waters.During the pre whaling era the demand for whales was also much lower as their oil was not considered as vital due to a lack of technological advances and little need for it in regards to pre 16th century industrial equipment.In 1931 international agreements were made between various countries to minimize whale killings in an effort to help several species recover due to the endangered status of whales which was caused largely by the whaling industry.The International Whaling Commission was created to monitor the whaling industry and limit their hunting efforts.In 1986 the International Whaling Commission adopted a moratorium to prevent all whaling activities in the countries that signed into the agreement and established stronger legal actions among those caught participating in whaling activities.Unfortunately even though agreements exist between various countries those that did not opt into the agreement are only bound by their countries own regulations on whaling (if the country has imposed regulations), which means that there are still countries today that consider whaling a source of industry.Today however countries and companies that still hunt whales primarily hunt them as a source of food (in some areas whale meat is considered a delicacy) because other practical uses such as lamp oil, cosmetics and candles no longer require the parts or oil of whales to be produced.© Copyright 2019 by Break.com. Why are blue whales an endangered species? Why blue whales are so enormous. Today, their numbers are slowly increasing, but they are still listed as an endangered species. They belong to a family of whales known as baleen whales and all of the 15 species in this family have baleen plates, instead of teeth, that allow them to filter food from the water. Status: Endangered Number Remaining: 10,000 to 25,000 Average Length: 80-100 feet Average Weight: about 200 tons The blue whale is the largest animal on our planet.
Whale meat that is processed in Iceland is shipped to Japan for consumption.
The blue whale is not only one of the most well-known species of whale, it’s also the largest known whale in existence growing to lengths of over 100 ft and weighing more than 150 tons; although 60 – 80 ft. is more common.In the past (pre whaling era) blue whales were extremely abundant (150,000 – 200,000 before whaling began) and found swimming in all of the major oceans of the world, however today it is estimated that there are now only between 1,500 – 2,500 blue whales left in existence.Because of their large size and supply of blubber blue whales were an extremely popular species to hunt and whalers would sell their blubber and body parts to suppliers who made various materials out of it.During the 1,700′s whale blubber & oil became a lucrative business largely due to a growing industrial age and increasing dependency on oil combined with advances in technology and boating which made it easier for whalers to hunt, kill & capture whales, which quickly lead to a highly competitive (international) whaling market, and thus the whaling industry was born.As technology, boats, and hunting equipment continued to evolve throughout the centuries the rate at which whales were being killed greatly increased and continued to shrink the existing whale populations, especially those of the blue whale and because blue whales were so large and whalers got paid top dollar for these mammals they were continually hunted by competitors until near extinction.As whale populations declined significantly organizations such as In addition to the assistance these organizations provided towards the monitoring and regulation of whale hunting increases in technology and cheap alternative resources provided companies & suppliers with alternative methods of producing & selling their products without the need to use whale oil as a source of fuel or as an ingredient in their materials.Although whales were being killed since the B.C.
The blue whales are currently classified as endangered by the IUCN. As whales lie at the top of the food pyramid, any decline or increase in their population is an indication of a change in their habitat.

Initially, the blue whale was not targeted by whalers because of their speed, size and power. It is probable that the two major threats facing these whales are the vessel strikes and the entanglement in fishing gear.
Humans began hunting whales (called whaling) in large numbers around the 17th and 18th century. Blue whales were once common in virtually all of the oceans on the planet, but there population declined rapidly in the 1900’s. killed one or two endangered blue hybrid whales, believed to be a mix of fin and blue whales (two very endangered whale species). However, in 1864 whaler Svend Foyn began using harpoons for catching large whales.
Recently, a whaling company in Iceland called Hvalur hf. Whaling is not done by traditional methods but with exploding harpoons that kill these mammals in a painful way.
