The blue whale
Once upon a time, someone loved reading, and he took the book from a bookshelf and started reading. He has read that the blue whale is a mammal of gigantic size and strength. It is an enormous living creature on our planet, and a blue whale can measure up to a hundred feet that are as large as a truck, digger, train, car, bicycle, motorbike, van, and tractor all lined up. The blue whale's heart is the biggest of any animal. It is as big as a small car and weighs about 1,300 pounds. The blue whales are gray, but they look bright blue underwater, so they got their name. The blue whale's skin color ranges from dark to light gray and is mottled like marble, feels smooth rubbery, and slippery to the touch of a blue whale's underbelly. It sometimes appears yellowish-white this happens when microorganisms called diatoms attach themselves to it.
Every blue whale has their unique markings similar to a human's fingerprint; Many scientists use these along with the shape of the dorsal fin to identify individual whales; an average blue whale weighs about 160 tons or about the same as a heap of 55 hippopotami females grow bigger and heavier than the males because the female cares for her baby independently and needs to be big enough to produce enough milk to feed it. No land animal can be as big as a blue whale because no bone structure can be strong enough to support such colossal weight out of the water. The salt in seawater helps keep these giant whales point-c water gives buoyancy to all other creatures -like hippopotami and humans. The blue whale's eye is about six inches wide and has no tear glands or eyelashes.
It is very small, considering the size of its body. The blue whales have poor eyesight and a poor sense of smell and taste, but their hearing is excellent, and their skin is susceptible. The top of a blue whale's mouth is lined with 300 to 400 baleen plates made of black fingernail-like material. A blue whale's tongue weighs three tons, and this mouth is so big that 50 people can stand inside it. Fortunately, blue whales don't eat people blue whales eat mostly krill a tiny shrimp-like creature during the summer months, they eat about 35 million krill each day which is about 4 tons of food but since they have narrow throat's they can only support they can swallow only a grapefruit-sized amount at one time blue whales eat different species of creole depending on the ocean in which they live to eat the blue whale takes a giant gulp of seawater in creole takes so much water into its mouth.
that the ventral pleats below its jaw and belly expand like a huge accordion when the blue the whale is ready to swallow it pushes all the seawater back out of its mouth with its tongue through its bristly baleen plates these plates catch the krill for the whale to swallow because krill are bright orange, so too is a whale's Pooh blue whales don't, baby blue whales don't eat krill they drink their mother's milk a baby blue whale is called a calf and its mother account the calf is in its mother's womb for almost a year and is about 20 feet long Webber's is born it drinks nearly 50 gallons of its mother's milk every day.
And can gain as much as 9 pounds an hour by eight months the calf will start to feed itself by eating krill blue whales have approximately the same lifespan as that of humans today scientists can determine all whales age by tracking it from birth using photographic identification scientists used to identify via blue whales approximate age by using the waxy earplug found inside his ear canal just as we can tell the age of a tree by counting the rings of his trunk.
Scientists could figure out the age of a whale by Counting the bands of wax that have built up over time this method could only be used on captured whales however, so it was eventually abandoned as unethical as well as unreliable blue whales aren't able to breathe underwater, but they can hold their breath for up to 30 minutes depending on their activity when they come up to the surface for blue air whales exhale through two nostrils like blowholes blowing air as high as 32 feet the height of nine seven-year-old boys a single breath could inflate 2,000 balloons the sound of a blue whale blowing is thunderous, and it can be heard up to several miles away.
The blue whales are graceful streamlined swimmers each side of its tail is called a fluke and together, these two flukes measure about 18 feet the width span of a small plane flukes move up and down like a bird's wing not side to side like a fish's tail blue whales also have a the small triangular dorsal fin on top of their backs and two short tapered flippers together help them to steer. a blue whale's ears are located near its eyes and are tiny little holes although these blue whales have excellent hearing this is important because they have to be able to hear each other in the ocean across great distances their the song is louder than a jet air engine and can be heard up to a thousand miles away they are one of the loudest animals in the world but the frequency of their sound is so low for humans to hear it without the use of equipment,.
The blue whale song resembles a foghorn and vibrates for the water with pulses moans and rumbles sound is essential to blue whales for both the communication and navigation guides them through the ocean towards food and helps them find a mate however the noise coming from ships and other manufactured vessels is often so loud that it interferes with marine life and can even confuse a mammal as large and loud as the blue whale the blue whale has been found in all the oceans of the world there are three subspecies of blue whales have you been ever know the blue whale well.
The Northern Hemisphere blue whale and the Antarctic blue well most blue whales feed on krill during summer months and then migrate to warm areas near the equator for the winter where pregnant females give birth blue whales sleep by taking very short naps while slowly swimming close to the ocean surface this is called logging they sleep in that way because they have to remember to open their blowhole in order to breathe most whales can never wholly lost their consciousness not even in sleep otherwise, they would drown, people can drift into sleep without having to remember to breathe and keep themselves afloat so we can fall asleep over a favorite book and begin to dream
