African Elephant - 10 - 12 feet tall / 5 - 7 tonnes ------ > The largest land animal today

Tyrannosaurus Rex - 14 - 15 feet tall / 6 - 9 tonnes ------ > One of the largest carnivorous dinosaur

Paraceratherium - 18 - 20 feet tall / 15 - 20 tonnes ------ > The largest land mammal

Brachiosaurus - 40 - 50 feet tall / 40 - 50 tonnes ------ > One of the largest herbivorous dinosaur

Blue Whale - 80 - 100 feet long / 100 - 200 tonnes ------ > The largest of all animals known so far.

(Human - 6 feet tall)

There's one animal that exists today that measures up to the ancient behemoths. The blue whale can measure up to 100 feet in length and weigh as much as 150 tons. Today most blue whales only reach lengths of 75 to 80 feet because whale hunters tend to target the largest of the species, according to experts. About 50 people could stand on the tongue of an adult blue whale. Even a baby blue whale is gigantic — a newborn calf can be as long as 25 feet and drink as much as 100 gallons of its mother's milk a day. Endangered since the mid-1960s, only 10,000 blue whales are believed to still exist.

From what I see in the photos, the blue whale is indeed the largest animal in our planet. Is there another animal that is larger than the blue whale and could be the largest in the planet?

yes, a few Sauropod dinosaurs may have been longer than the Blue Whale (over to 40 meters long) and almost as heavy.

the problem however is that most of these largest of dinosaurs had very incomplete remains found (like a single tibia, etc) and from these the total size was extrapolated comparing it to sauropods who had more complete skeletons. Like: ok, if a diplodocus has a tibia of 1.2 meters, how big would a similar species with a 2 meters long tibia be?





in the photo below it´s a brachosaurus, which is quite "smaller" than the giant ones from above, or Argentinosaurus, etc



http://svpow.com/2008/05/20/sv-pow-s...ods-vs-whales/
Quote:
Then there are the semi-apocryphal gigapods, Bruhathkayosaurus and Amphicoelias fragillimus. Bruhathkayosaurus is reported to have a 2-meter-long tibia, which would make it perhaps 20% larger than Argentinosaurus in linear terms, and 70% more massive (mass scales with the cube of the linear dimension, and 1.2 x 1.2 x 1.2 = 1.728). Assuming that the proposed tib is really a tib and not an eroded femur or something, and that Bruhathkayosaurus was built like the very robust Argentinosaurus and not like, say, the very slender Brachiosaurus, and that the mass estimate for Argentinosaurus is accurate, Bruhathkayosaurus may have weighed as much as 139 tons (126 metric tons).

Amphicoelias fragillimus appears to have been built like a big Diplodocus–well, okay, an extremely mind-blowingly immense Diplodocus–and assuming the sole surviving drawing is legit and correctly scaled, it was just completely nuts (way more so than Apatosaurus; see Darren’s thoughts here and here). The femur may have been anywhere from 3-4.6 meters long (Carpenter 2006), and was more likely in the upper part of that range. In the big mounted skeletons of Diplodocus, the femora are just a little over 1.5 meters long. So Amphicoelias may have been 2-3 times the size of Diplodocus in linear terms. Carpenter (2006) posited a length of 190ft (58m) and a weight of 135 tons (122.4 metric tons).

and anyway, even without Amphicoelias, we ARE discovering giant sauropods in Argentina... Argentinosaurus, Puertasaurus... last wekk there was a new giant one discovered

^ I'm guessing it's because the brain is predominantly occupied in controlling their immensely heavy duty motor functions. Also, the way they are required to use their intelligence for survival might be be different from what a human being might have to do for survival, considering the differences in physiology, so they can't exactly be called stupid (since they do what is required of them to survive). But I'm no expert on the subject so don't take my word for it.

Why exactly does a larger body require bigger brain? Doesn't really make sense.

Look at those huge Dinosaurs from above. Their brains where tiny and still their bodies were completely functional.

Yah, I don't know but a small monkey's more intelligent than a cow although brain of monkey's smaller than cow brain.
Now, holding your hand, that's your heart size. How is size of whale heart? Looking under model.


http://media.cleveland.com/plain-dea...5-standard.jpg

Its heart weighs 600 kilograms (1,300 lb)

And what are under objects? Can you guess them?

http://freethoughtblogs.com/lousycan...eseventeen.jpg
UFO on sea


http://www.mentalfloss.com/sites/def...7/07/whale.jpg

average length is 8 feet (2.4 m) to 10 feet (3.0 m),
each weighing is 100–150 pounds (45–68 kg) Its weight is probably one adult man.

Well, those dinosaurs are much more stupid than whales.

anyway, read:
https://en.wikipedia.org/wiki/Encephalization_quotient

Quote:
Encephalization Quotient (EQ), or encephalization level is a measure of relative brain size defined as the ratio between actual brain mass and predicted brain mass for an animal of a given size, which is hypothesized to be a rough estimate of the intelligence of the animal.[5]

This is a more refined measurement than the raw brain-to-body mass ratio, as it takes into account allometric effects. The relationship, expressed as a formula, has been developed for mammals, and may not yield relevant results when applied outside this group.[6]

Additionally to volume, mass or cell count, the energy expenditure of the brain could be compared with that of the rest of the body.

...

Brain-body size relationship

Brain size usually increases with body size in animals (is positively correlated), i.e. large animals usually have larger brains than smaller animals.[7] The relationship is not linear, however. Generally, small mammals have relatively larger brains than big ones. Mice have a direct brain/body size ratio similar to humans (1/40), while elephants have a comparatively small brain/body size (1/560), despite being quite intelligent animals.[7][8]

Several reasons for this trend are possible, one of which is that neural cells have a relative constant size. Some brain functions, like the brain pathway responsible for a basic task like drawing breath, are basically similar in a mouse and an elephant. Thus, the same amount of brain matter can govern breathing in a large or a small body. While not all control functions are independent of body size, some are, and hence large animals need comparatively less brain than small animals[citation needed]. This phenomenon has been called the cephalization factor: E = CS2, where E and S are body and brain weights and C is the cephalization factor.[9] To compensate for this factor, a formula has been devised by plotting the brain/body weight of various mammals against each other and a curve fitted so as to give best fit to the data.[10]

The cephalization factor and the subsequent encephalization quotient was developed by H.J. Jerison in the late 1960s.[11] The formula for the curve varies, but an empirical fitting of the formula to a sample of mammals gives Ew(brain) = 0.12w(body)2/3.[6] As this formula is based on data from mammals, it should be applied to other animals with caution. For some of the other vertebrate classes the power of 3/4 rather than 2/3 is sometimes used, and for many groups of invertebrates the formula may give no meaningful results at all

Comparisons with non-mammalian animals[edit]
Manta rays have the highest for a fish,[16] and either octopuses[9] or jumping spiders[17] have the highest for an invertebrate. Despite the jumping spider having a huge brain for its size, it is minuscule in absolute terms, and humans have a much higher EQ, despite having a lower raw brain-to-body weight ratio.[18][19][20] Mean EQ for reptiles are about one tenth of the EQ for mammals. EQ in birds (and estimated EQ in dinosaurs) generally also falls below that of mammals, possibly due to lower thermoregulation and/or motor control demands.[21] Estimation of brain size in the oldest known bird, Archaeopteryx, shows it had an EQ well above the reptilian range, and just below that of living birds.[22]

Biologist Stephen Jay Gould has noted that if one looks at vertebrates with very low encephalization quotients, their brains are slightly less massive than their spinal cords. Theoretically, intelligence might correlate with the absolute amount of brain an animal has after subtracting the weight of the spinal cord from the brain.[23] This formula is useless for invertebrates because they do not have spinal cords or, in some cases, central nervous systems.

EQ and intelligence in mammals[edit]
Intelligence in animals is hard to establish, but the larger the brain is relative to the body, the more brain weight might be available for more complex cognitive tasks. The EQ formula, as opposed to the method of simply measuring raw brain weight or brain weight to body weight, makes for a ranking of animals that coincide better with observed complexity of behaviour.

Mean EQ for mammals is around 1, with carnivorans, cetaceans and primates above 1, and insectivores and herbivores below. This reflects two major trends. One is that brain matter is extremely costly in terms of energy needed to sustain it.[12] Animals which live on relatively nutrient poor diets (plants, insects) have relatively little energy to spare for a large brain, while animals living from energy-rich food (meat, fish, fruit) can grow larger brains. The other factor is the brain power needed to catch food. Carnivores generally need to find and kill their prey, which presumably requires more cognitive power than browsing or grazing.[13][14]

Another factor affecting relative brain size is sociality and flock size.[15] Rabbits, being solitary animals, have lower EQ than horses, a social species. Similarly, dogs (a social species) have a higher EQ than cats (a mostly solitary species). Animals with very large flock size and/or complex social systems consistently score high EQ, with dolphins and orcas having the highest EQ of all cetaceans,[3] and humans with their extremely large societies and complex social life topping the list by a good margin.[1]


Body Size, Brain Size, and Encephalization Quotient, among cetaceans. Note that EQ denotes much better their real intelligence.




but even EQ only serves for statistics... and it´s not perfect. There are other factors involved.
https://en.wikipedia.org/wiki/Human_brain

Quote:
The human brain has the same general structure as the brains of other mammals, but has a more developed cortex than any other. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans.

If there is not person in the earth, blue whale is the happiest animal. They need not more intelligent because they are very big, no animal can not kill them. They only eat small shrimps, play with their friends, sleep and give birth... Blue whale have a happy life until die at about 100 years of age.

Why do you have to more inteligent but have an unhappy life?
Person, one animal has average size, can kill all of blue whales or any animal on the earth. That's the best amazing creature in the earth. Maybe blue whales think us horrible small ghost of the earth.

Yeah I am aware of that EQ. But it still doesn't make sense why whales need such huge brains.
To control the body a much smaller brain would be sufficient (see sauropods) and for intelligence absolute brain size should be relevant and not relative. A chimp size brain would be more than enough to make them stand out in the animal kingdom as one of the smartest mammals. A human size brain would be therefore more than sufficient to control the body and explain their intelligence.

IMO, the whale brain is just huge because it grew together with the body during evolution and to fill the cranial cavity. Apparently its much easier to just increase the brain than to downsize the internal skull structure to house a smaller brain.
