Blue Whales

Whales, dolphins, and porpoises are mammals that breath air. The problem they have is when they beach themselves on land; then without water to support their bodies, they collapse on their lungs and die, also from exposure to the elements.

People.

It used to be hunting. Now we're killing the whale's food (krill) with a combination of overfishing and warming the planet.

People catch about 200,000 tons of krill per year.

As if catching all the krill isn't bad enough, climate change is melting sea ice, which is where the krill's food lives. So, a warming ocean kills off marine algae, which means that krill numbers drop, which means that blue whale numbers drop.

Blue whales communicate with each other by using a series if high frequency sounds that can only be herd by their species. The also use other ways to communicate by flapping their fins and tail in a certain way. The baby whales learn those things form their mothers like we learn words when we are babies.

Because they are both blue.

Maybe so they can blend in and because blue oceans are big

Because they are whales and are meant to live in the ocean, just like humpback whales or any other whale lives in the ocean.

A group of whales is called a pod no matter what kind they are.

It is possible to, as they are not hostile to humans. However it would be extremely dangerous. The whale views you as you would view an insect, it is an unreal amount bigger and heavier than a human. So although it most likely won't harm a person (as long as they don't fear for their calf), it is very capable of killing u by accident.

The gestation period is around 10 to 12 months. Females typically give birth to one calf every two to three years at the start of winter. The new born is 2.5 metric tons heavy and is around 7 meters long at birth. He drinks nearly 400 liters of milk every day and gains around 100 kilos of weight almost every day when he grows

Offcourse just like all other vertebrate animals.

the average blue whale is 18 metres longer than a salt water crocodile.

to be honest i have no idea but i do know its about the size of a car now thats pretty big

blue whales have baleen this is a type of broom bristle fiber and it is only located on the top of its mouth this helps it swallow its favorite fish herring.

Yes, the blue whale is the biggest creature to live on the Earth.

Like all animals, whales need oxygen, which they get by coming to the surface to get a breath of air. They need water, which they drink from the ocean, and then they filter out the excess salt through their kidneys. They also need food, which, for most whales, means krill or small fish. Most species of whale can only get food from the polar regions, and therefor their habitats their need to be protected. During the winter, most whales move south to tropical or subtropical waters to breed. These areas must also be protected. The primary threat to whales is human whalers, which, thanks to an international treaty, has almost ceased. However, Japanese whalers are still taking their toll on the whale population. For people to protect whales, the Japanese must stop whaling soon.

Sure in the same way dolphins are related to pigs....

they are (or in the case of mammoths were) mammals.

Blue whales are absolutely harmless due to their large mass and weight.

A blue whale is about 3300 centimeters long.

The whales with teeth are called toothed whales. The ones that don't have teeth are called baleen whales. Baleen whales use filters to drain out water from plankton.

Only one. The same as every whale or dolphin.

The newborn blue whale calf weighs about 2.5 metric tons (2.8 short tons) and is around 7 metres (23 ft) in length.

A newborn sperm whale calf is about 13 feet (4 m) long and weighs about 1 ton (0.9 tonnes).

probably the mamouth, elephant, dynosaur, or the whale. I've never thought bout it. idk, maybe some of my answers r right.

from the things it eats

Adult blue whales have no natural predators. They are too big and too strong to be attacked and killed by any animal. However, Orca's (Killer Whales) are known to attack and kill youngsters. A group of Orca's can easily hunt a baby blue whale if its mother is not around. Otherwise, they have no natural predators

Humans are the biggest threat to blue whales. Nearly 90% of the world population of these animals were wiped out over the past century by humans by whaling.

No.

All cells are the same size and shape, depending on the exact species of the cells. All cells are microscopic.

However, because whales are bigger, they have billions of more cells than a human.

Humans have been the biggest and most dangerous predators of the blue whales. With large ships and powerful harpoons humans killed these gentle giants in thousands. By 1970 330,000 blue whales had been caught & killed in the Antarctic, 33,000 in the rest of the Southern Hemisphere, 8,200 in the North Pacific, and 7,000 in the North Atlantic. The largest original population, in the Antarctic, had been reduced to 0.15% its original count.
