Detailed explanation-1: -The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400, 000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.

Detailed explanation-2: -Blue whales are the largest animals ever to live on our planet. They feed almost exclusively on krill, straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day.

Detailed explanation-3: -The blue whale is the largest mammal in the world. Blue whales are able to breathe air, but they are very comfortable in the ocean waters where buoyancy helps to support their incredible bulk. These mammals are found in all the world’s oceans and often swim in small groups or alone.

Detailed explanation-4: -The fin whale is the second largest animal to ever live, in the entire history of Earth. Reaching lengths of at least 85 feet (26 m) and weights of 80 tons, this species is second only to its close relative, the blue whale.

Detailed explanation-5: -The blue whale is the largest creature in the world and has been found in every ocean in the world. A marine biologist surveyed the blue whale population in Monterey Bay, off he coast of California, every three years between 1995 and 2010. The figure shows her results.
