How many humans fit in a whale?
School buses can seat as many as 40 people. So about 80 people could hang out on a blue whale. I don't think the whale would appreciate all those folks invading its space, but they've got the room! They're longer than 6 midsize passenger cars (about 15 feet/4.5 meters each).
An adult blue whale can grow to about 30m long and weigh more than 180,000kg, equivalent to around 40 elephants, 30 Tyrannosaurus rex dinosaurs, or about 2,670 average-sized men.
That would not take the heavyweight title by itself. The biggest blue whale ever recorded weighed 190 tons, according to Guinness World Records.
Blue whales can grow up to 100 feet (~30 m). Lengthwise that's the equivalent of two city buses and longer than an NBA basketball court. They can weigh up to 200 tons. That's about 8 DC-9 aircrafts or 15 school buses.
Amazing, whales have some of the smallest sperm of all mammals. They vary from 50-75 microns, whereas human sperm are 40-90 microns long. It is thought that whales have such small sperm because the female reproductive tract is so large that having longer sperm doesn't give a male any extra advantage.
Oxygen is pumped around its enormous body by an equally massive, four-chambered heart.
Some larger estimates do exist (placing megalodon up to 67 feet in length and well beyond 50 tons), but the fact of the matter is megalodon was smaller than a blue whale. In terms of size, a blue whale gets the advantage. Blue whales are larger and heavier than a megalodon.
In what was likely a once-in-a-lifetime opportunity, a group of amazed onlookers witnessed a grey whale give birth to a calf near Dana Point off the coast of California on Monday.
The biggest animal that lives in the sea is the blue whale. Blue whales can grow to 30 metres long, weigh up to 200 tonnes and have a heart the size of a small car! The blue whale is also the biggest animal on the planet and the largest animal that has ever lived!
How do whales sleep?
To be able to sleep, whales shut down half of their brain at a time. Being partially awake allows them to continue breathing and be aware of their surroundings. Whales will usually stay in place as they sleep near the surface. As they rest, they are switching which hemisphere of the brain is awake.
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 long and upwards of 200 tons. Their tongues alone can weigh as much as an elephant.

Cruise ships are at least ten times larger than whales. The average cruise ship is 1,000 feet long, whereas the largest blue whales are no more than 100 feet long.
Not only are these organs huge and efficient, but they also serve an important ecological purpose even after death. A blue whale heart can be 5ft tall (1.5m), weigh over 400 pounds (200kg), and have tubes as large as the tubes in a jungle gym for small children!
Whales also emit low frequency sound waves. These waves are like hills that are wide spread apart. These sound waves can travel very far in water without losing energy. Researchers believe that some of these low frequency sounds can travel more than 10,000 miles in some levels of the ocean!
It has been estimated that the beluga whale has an IQ of 155, however, animals cannot accurately be given an IQ since it refers to their ability to solve problems. An IQ of an animal will always be restricted to the individual life processes such as food availability and threats 5 .
Drosophila bifurca is a species of fruit fly. Males of this species are known to have the longest sperm cells of any organism on Earth—5.8 cm long when uncoiled, over twenty times the entire body length of the male. The cells are mostly tail, and are delivered to the females in tangled coils.
The discovery of spindle cells in the brains of some whale and dolphin species provides good supporting evidence that these species may be capable of experiencing complex emotions such as empathy and indeed that this emotion may provide an important evolutionary advantage for these highly social species.
The weakest animal you could beat in a fight is a rat or cat (around 70%) while the strongest animal you could beat is a grizzly bear, lion, elephant, or gorilla (around 3%). The other animals include goose, dog, eagle, chimpanzee, cobra, kangaroo, wolf, and crocodile.
In addition to being the world's largest fish, megalodon may have been the largest marine predator that has ever lived. (Basilosaurids and pliosaurs may have been just as large.)
Has whale 52 ever been seen?
However, the whale itself has never been sighted; it has only been heard via hydrophones. It has been described as the "world's loneliest whale", though potential recordings of a second 52-hertz whale, heard elsewhere at the same time, have been sporadically found since 2010.
It is an unusually high frequency for whale vocalisations, and Watkins was intrigued enough to search for 52 until his death in 2004. But despite picking up 52's call every year, Watkins never found the mysterious whale.
It's thought that megalodon sharks became extinct in part due to climate change: as oceans grew colder, they may not have been able to regulate their temperatures as needed. Lack of prey could be behind the megalodon's extinction, as many marine animals and fish could not survive the cold temperatures.
Is the megalodon still alive? 'No. It's definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,' notes Emma. 'If an animal as big as megalodon still lived in the oceans we would know about it.'
The megalodon is considered the largest shark to have ever lived, according to the Natural History Museum. Records of megalodons date to around 20 million years ago, and the shark is a distant relative of the great white.
Not only would the whale's stomach acid make quick work of you, but you'd experience a distinct lack of air on the inside [source: Eveleth]. Of course, you're much more likely to get eaten or maimed as you try to make it past the sperm whale's sharp teeth, which are roughly as long as a large steak knife.
Depending on the particular species of whale, a gestation period can be anywhere between 9 to 16 months.
James Bartley (1870–1909) is the central figure in a late nineteenth-century story according to which he was swallowed whole by a sperm whale. He was found still living days later in the stomach of the whale, which was dead from harpooning.
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
The blue whale (Balaenoptera musculus) is the largest animal on the planet and is often referred to as the “king of the ocean.” These massive creatures can grow up to 100 feet in length and weigh over 200 tons.
Do whales ever stop swimming?
The ability of different species of cetaceans to hold their breath varies between a few minutes and over an hour. Their sleeping habits are also non-standard. Humpback whales, for example, have been found resting motionless on the surface of the water for about 30 minutes.
Despite a few exceptions, pinnipeds and cetaceans do not usually drink. In most cases, water is supplied by the metabolism of prey proteins (metabolic water) and the oxidation of fat (drinking water). In cetaceans, these waters may be sufficient to maintain a water balance in the body.
Like humans, whales are mammals. They therefore have lungs and breath air at the surface. They are unable to extract oxygen from the water like fish do with their gills. Breathing in whales is “conscious”; the function of breathing in these animals is under the voluntary control of the central nervous system (CNS).
#1—Blue Whale
Not only is the blue whale the largest animal to live on the Earth today, they are also the largest animal to have ever existed on Earth. A blue whale can grow up to 100 feet long and weigh upwards of 200 tons.
Howler Monkey – 140 dB
The howler monkey is the loudest animal on the land. It can create sound up to 140 decibels which can be audible from a space of three miles. They are found in a form of groups of six to fifteen monkeys.
The blue mammal is also incredibly heavy: 170+ tonnes, in fact. This is over four times larger than a sperm whale and over 2,400+ the size of a human. Some blue whales are estimated to be as large as 190 tonnes.
The Antarctic blue whale (Balaenoptera musculus ssp. Intermedia) is the biggest animal on the planet, weighing up to 400,000 pounds (approximately 33 elephants) and reaching up to 98 feet in length.
Northern right whales females grow to be about 50 feet (15.5 m) long, males are about 49 feet (15 m) long and weigh approximately 120,000 pounds (54,000 kg). Southern right whale females are about 54 feet (16.5 m) long, males are about 50 feet (15.2 m) long.
Fossil findings prove that the Argentinosaurus was one of the largest known animals of all time, if not the largest. During the late Cretaceous period, a genus of enormous sauropod dinosaurs called Argentinosaurus existed in what is now Argentina.
'For example, a blue whale has a much bigger brain than humans, but it's much smaller than ours would be if you blew a human up to the size of a blue whale without changing our proportions. '
What is the 2nd largest animal in the world?
Rank | Animal | Average total length [m (ft)] |
---|---|---|
1 | African bush elephant | 7 (23) |
2 | Asian elephant | 6.8 (22.3) |
3 | African forest elephant | 6.2 (20.3) |
4 | White rhinoceros | 4.4 (14.4) |
The largest land animal on earth currently is the African elephant. There have been animals far greater than an African Elephant in the 4 billion-year history of Earth, one of those is called Argentinosaurs. These are the world's biggest land creatures ever, that lived in what is now South America.
The blue whale is the biggest living being alive today and it is far larger than any megalodon. The blue whale can grow upwards of 100 feet long and weighs more than 110 tons. Simply put, this is an absolutely massive mammal that has no equal.
A single fin whale is thought to produce around 1,000 liters (260 gallons) of urine each day — enough to fill a 10-by-6-foot kiddie pool.
Whales have huge mouths, but...
Their throats are relatively small. A Blue Whale's throat is only as big as a basketball, so it can barely swallow something bigger than a grapefruit (but that's okay, it doesn't need to when it eats krill!).
As this whale is the largest mammal on earth, its size reaches lengths of up to 110 feet long! To translate just how big a blue whale is, it's almost half the length of a football field and nearly 20 feet longer than a professional NBA basketball court.
