Blue Whales
The Blue Whale is the largest animal in the world and can weight from 100 – 160 tons. This large species of whale can be found in oceans worldwide, mainly in deep, open areas with cold waters. Hunted by whalers, the Blue Whale was once nearly driven to extinction and is still considered as endangered today. This category has questions about the Blue Whale’s appearance, diet, etc.

Where you can find the blue whale now?
Blue Whales can be found in almost every sea and ocean in the world. They were the most widely spread whale species until Man started hunting them down. They were once in numbers of around 200,000 or more and now there are only 20,000 or so animals left in the wild.
They can be found in areas that are abundant in "Krill" their favorite prey species.
They don't live in family groups. They are solitary animals. They are known to be along one or two individuals at most and that too only for short periods of time.
What is heavier a blue whale or an elephant?
A blue whale is much heavier. An elephant can weigh up to 6 tons. A blue whale can weigh up to 200 tons.
A mature bull Elephant can weigh 9,000lbs -13,000lbs (4,500-6,000 kilos). A mature blue whale can weigh 230,000lbs-300,000lbs (108,000-136,000 kilos).
The blue whale is not only the largest living animal on earth, it's the largest animal that has ever lived on earth.
People say humans are the smartest animals on earth, but new studies have found that Orca communities and language are far more complex than our own. This is likely due to the brain of an Orca, which, alongside the parts we carry only larger, they have an added frontal lobe that enhances emotion and attachment to others in their pod. They are also very advanced and peaceful, outside their hunting techniques. No single person has ever been attacked by an Orca in the wild. Given the empirical evidence, I'd have to say there's a 50% chance they are smarter than humans.
Is a lion bigger than a blue whale?
No. A grizzly bear has bigger jaws and a larger size with more strength and weight.
Is the Irish wolfhound bigger than a horse?
Most of the time... Irish Wolf hounds aren't directly related to wolves so they are no the same thing
How deep can a Blue Whale dive?
The blue whale can dive for 10-20 minutes and dive for 500 metres deep.
Do blue whales live in the long island sound?
Yes. Several species of cetaceans inhabit Long Island Sound, including large baleen whales such as the North Atlantic right whale and smaller toothed species such as bottenosed dolphins and harbor porpoise.
Why are blue whales threatened?
They are threatened because of hunters, they are hunted for their fat. Whale fat is used in mascara.
How much does the blue whale weight?
A blue whale can weigh as much as 200 short tons (400,000 lbs).
An adult blue whale can weigh up to around 180 metric tons (400,000lbs). A blue whale calve can weigh up to 2.7 metric tons (almost 6000lbs)
Female Blue whales are generally larger than the males, but on average Blue whales can grow between 80 to 108 feet long and can weigh up to 120 tonnes. Newborn calves are approximately 22ft long and around 6 tonnes at birth. Exact measurements are difficult to calculate due to their extreme size.
What is the hole called through which whales breath?
Whales have lungs and come to the surface to breathe. Their nostrils called blowholes are located on the top of the head to access air easily. Whales exhale, condensation from the 2 blowholes forms a 'v-shaped' 'blow'. when they submerge they hold their breath.
How are blue whales trying to be saved?
some people are taking them into captivity and aome are watching them by putting on a location tracker so they can find out where they mostly are and that's were captivity comes in also so the people can give them some medicine PLEASE SAVE THE WHALES PEOPLE I AM A 11 YEAR OLD THAT WANTS TO HELP ALL THE WHALES
How does a blue whale protect itself?
Its size is its protection from most dangers, everything is too afraid to attack.
That is not strictly true, a pod of killer whales will pursue very young, old, sick or injured blue whales for hours, until they are too tired to go any further. They will then go in for the kill and share the spoils.
The average length of a blue whale is to 82ft for males. Female blue whales can measure 85ft. The largest whale measured at 98ft.
Why do non toohted blue whales have two blowholes?
Toothes whales eat other animals such as seals, fish and squid. Baleen whales have thick brush like baleen and eat by straining sea water through the baleen to filter out microscopic plants and animals.
The toothed whale have teeth but, the baleen whale have baleen. The toothed whale have jaws lined with sharp teeth but, the baleen whales have baleen hung from upper jaw. The toothed whale feed on fish, squid, etc. but, baleen whales feed on small sea life.
Baleen whales, or odontocetes whales, have baleen.
Toothed whales, or mysticetes whales, have teeth.
Can a human kill a blue whale?
One on one, a big 80 feet long blue whale would defeat a 30 feet long killer whale. However, when a pack (pod) of killer whales team up, they can kill an adult blue whale, although they usually prefer to attack a calf, or a pregnant female, which are weaker than a adult male blue whale.
Do Blue Whales jump in to the air?
Blue whales belong to the group Mysticeti, or the baleen whales, and typically produce sounds in the frequency of 10 Hz to over 30 kHz, which is well within the range of human hearing. The problem with hearing underwater sounds in the air, however, lies in the fact that to hear the sound in the air, the underwater sound waves must efficiently cross from the dense water into the much less dense air.
Sound is made up of vibrations within a medium, whether that be water or air. Underwater sounds vibrate water molecules, but for those underwater sounds to carry through the air, the vibrating water molecules must transfer their energy to air molecules. The problem with hearing underwater sounds in the air is that the water is rarely still, so that the energy of the underwater sound wave is dissipated, or spread out, over the surface of the water and results in the sound being lost to the waves.
If the water were perfectly still, however, the surface of the water may act as a very inefficient membrane (much like a speaker) to transfer the underwater sound waves to the air, but even then the sound would be very distorted due to the inefficiency of the transfer.
How does the blue whale survive in its habitat?
Most mammals that live in cold climates have thick fur to keep them warm. A whale has no fur. But it does have thick skin. This skin is lined with blubber. Blubber is a layer of fatty tissue just beneath a marine mammal's skin. The blubber of a whale is 3 to 4 inches (7.6 to 10.1 centimeters) thick.
Blubber acts like an extra layer of clothing. It covers most of the whale's body. Only the flippers, the flukes, and the dorsal fin lack blubber. Blubber keeps out the cold and traps heat in. Without blubber, the whale couldn't survive in icy waters.
A whale can also turn its blubber into energy, which heats up the animal's body. The whale can live off this fatty layer when it can't find food. When there is plenty of food, the whale will build its layer of blubber back up.
How long are a whale blue whale's intestine?
If you're going to copy and paste might as well include the whole thing. Hi Susie,
This NOAA site suggests that the intestine of large whales tend to be 5-6
times their total body length (see below). A blue whale's body temperature
is similar to humans, just under 100 degrees F. Sorry, I don't know what
the blood pressure of a blue whale is. It is true that there is generally
an inverse relationship between size and longevity with larger animals
typically living longer than smaller ones. Large whales do have long life
expectancies.
Hope this helps,
Cathy
The total capacity of the stomach of a large whale is about 760 liters (200
gallons). This is relatively small compared to the cow with a capacity of
209 liters (55 gallons) and the human with a capacity of 17 liters (4.5
pints). The first chamber in all whales is a dilatable, sac-like, extension
of the esophagus with no digestive glands. This is the compartment that
"chews" the food -- as the gizzard does in birds (remember -- baleen whales
have no teeth and toothed whales don't use their teeth to chew). In baleen
whales, the first compartment is quite small (little need to "chew" since
their prey is so small), while in toothed whales the compartment is
relatively large. The second chamber is where digestive juices are
released -- pepsin and hydrochloric acid have been found in this part of the
stomach of some whales. Most cetaceans have a third large chamber which is
the pyloric part of the stomach. The intestine is quite large, usually five
to six times the length of the body (human intestines run about two times
body length or about 12-13 feet in an adult). Baleen whales also contain a
distinctive caecum and colon, and, as with other mammals, have a pancreas
and liver which deliver digestive enzymes by way of a duct into the
digestive tract (there is no gall bladder in contrast to humans).

How much wider is a blue whale than a gray whale?
Blue Whales are the largest known species of animal ever known to man. Sperm whales are around 20 meters long while blue whales can be around 30 meters long and weigh twice as much as sperm whales.
How do you identify the sex of a blue whale?
the males dorsal fin is strait and tall on the back of the dorsal fin and little curved in the front,the females dorsal fin is curved both sides
Does a blue whale have a swim bladder?
No stingrays do not have a swim bladder. If they sink to the bottom they have trouble getting back up.
Whales are mammals, they don't lay eggs. However, as mammals, I'm fairly certain the females have eggs, which bond with sperm, just like other mammals, so I suppose you could eat those... if you could find any.
