What are some interesting facts about blue whales?

Answer 1

Some of the answer is blue whale is definitely the largest living warm blooded sea mammal ever existed on this planet and sometimes can reach a length of 30.5 meter (100 feet) and weigh over 100 tons.

On land an animal the size of a blue whale would be crushed by its own weight without the support of large heavy bones. Because its body is supported by water, as a sea animal, the need for heavy bones to support its weight disappeared. This, plus the availability of a large food supply, have made it possible for the blue whale to reach such an enormous size. The blue whale makes deep and rumbling sounds which can be felt as much as heard. These low frequency sounds travel long distances through water, allowing blue whales to communicate with each other over hundreds of miles of ocean.

Their scientific name is Balaenoptera musculus.

Also, in the 20th century, 99% of the Blue Whale population was killed by whalers!

Answer 2

Blue whales are the largest animals ever known to have lived on Earth. These magnificent marine mammals rule the oceans at up to 100 feet (30 meters) long and upwards of 200 tons (181 metric tons). Their tongues alone can weigh as much as an elephant. Their hearts, as much as an automobile.

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 (3.6 metric tons) of krill a day.

Blue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws. The giant animals feed by first gulping an enormous mouthful of water, expanding the pleated skin on their throat and belly to take it in. Then the whale's massive tongue forces the water out through the thin, overlapping baleen plates. Thousands of krill are left behind-and then swallowed.

Answer 3

• Most scientists agree that not only is the blue whale the biggest animal on earth, it is one of the biggest animals that ever lived.
• Blue whales live in groups called pods
• They are baleen whales, and eat small organisms such as krill.
• Their gestation period is about one year in length.
• When a female blue whale is pregnant, she migrates from cold Arctic waters to the tropics so she can give birth.

Answer 4

Here are a few interesting facts: They are the largest animals on earth (living today, so you don't count dinosaurs), their throat is the size of a grapefruit, a blue whale calf weighs two tons at birth, they feed mostly on plankton, which are two-inch-long creatures, and even though they are the largest animals on earth, they are the hardest whales to find. I hope you find these five facts interesting and useful.

Answer 5

There are over a dozen facts about blue whales but here are 2 interesting facts about blue whales

1. There average lifespan in the wild is 80 to 90 years.
2. When a blue whale exhales, the spray from its blowhole can reach nearly 30 ft (9m) into the air.

Answer 6

they live between 80 or 90 years blue whales are baleen

they eat krill they can weigh as much as 30 elephans they are greyes blue

Answer 7

On average, they measure at 82ft for males and 85ft for females. They can weigh between 100-150 tons. The biggest blue whale was a female that weighed 209 tons at length of 100ft.
