About Whales

Whales are the largest animals on Earth and they live in every ocean. The massive mammals range from the 600-pound dwarf sperm whale to the colossal blue whale, which can weigh more than 200 tons and stretch up to 100 feet long almost as long as a professional basketball court.

A blowhole is the hole at the top of the head through which the animal breathes air. In baleen whales, these are in pairs.

Blubber is a thick layer of vascularized adipose tissue under the skin.

What are Blowholes and Blubber?

          Diet of Krill

Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes about 4 tons of krill a day.

Blue whales look true blue underwater, but on the surface their coloring is more a mottled blue-gray. Their underbellies take on a yellowish hue from the millions of microorganisms that take up residence in their skin. 

Blue whales live in all the world's oceans, except the Arctic, they swim in small groups but usually alone or in pairs. They often spend summers feeding in polar waters and undertake lengthy migrations towards the Equator as winter arrives.

Calves enter the world already ranking among the planet's largest creatures. After about a year inside its mother's womb, a baby blue whale emerges weighing up to 3 tons and stretching to 25 feet. It gorges on nothing but mother's milk and gains about 200 pounds every day for its first year.
