The Blue Whale (Balaenoptera musculus) is the largest baleen whale and the largest animal that ever lived on Earth. Blue whales grow to be 80 feet (25 m). There are records of individuals over 100 feet (30.5 m) long, but 70-90 feet (23-27 m) is probably average. they are about as long as three school buses. An average weight for an adult is 200,000 to 300,000 pounds (100-150 tons). Its heart alone is as large as a small car.
They are called Blue Whales because this endangered animal is Blue Whales are an overall mottled blue-gray color. Cold water diatoms adhere to their skin and sometimes give their bellies a yellowish tinge, giving the blue whale its nickname of “sulfur bottom.” Blue whales are long and streamlined.
Blue whales are moving along their old migratory pathways from the southern coast of California to the Alaskan waters. This is the first time they have traveled along their old migratory route since the 1960s.
As long as we can stop the countries like Japan from killing
these silvery giants of the sea. they may make a comeback.
Blue whales were severely depleted during commercial whaling activities during the early 1900’s in the north Pacific and along the West Coast as far south as Baja California. Four of the whales, identified by the pigmentation patterns in skin color and shape of the dorsal fin were seen off the coast of California, Maybe they are going home to the coastal waters around Alaska.
