The 20 Biggest Mammals, Ranked by Category
Sep 17, · At feet long and tons, not only is the blue whale the biggest mammal in the world, but it's also the largest vertebrate animal that has ever lived. Not even the largest dinosaurs approached it in bulk. Some titanosaurs were over feet long, but they didn't weigh tons. Fittingly, the blue whale is also the loudest animal on earth. 3-the bowhead whale The bowhead whale is by far the largest animal in the arctic, at tons and feet makingoz.com can also live for makingoz.com its tongue weighs a ton-the same as a bison! 4-The sperm whale The sperm whale is an average 50–60 feet in length and often 30–40 tons.
Whales are really big, and a hippopotamus is roughly the same size as a rhinoceros. But do you know the biggest mammals by category?
Here's a list of the 20 biggest mammals, in 20 categories, starting with the biggest ot and ending with the biggest shrew:. At feet long and tons, not only is the blue whale the biggest mammal in the world, but it's also the largest vertebrate animal that has ever lived. Not even the largest dinosaurs approached it in bulk.
Some titanosaurs were over feet long, but they didn't weigh tons. Fittingly, the blue whale is also the loudest animal on earth. This cetacean can vocalize at decibels, enough to render most other animals deaf. Ammmal largest land-dwelling mammal on earth, at seven tons, the African elephant is smaller than the blue whale for good reason: The buoyancy of water helps to counteract the blue whale's weight, and elephants are terrestrial. One reason the African elephant has enormous ears is to help dissipate its internal body heat.
A warm-blooded, seven-ton mammal eve a lot of calories. How can the biggest dolphin be a whale? Killer whalesalso known as orcas, are classified as dolphins rather than whales. At six or seven tons, male rhe are bigger than the largest sharks, which means that killer whales, bave than great white sharksare the atop predators of the oceans. Sharks have livfd more fearsome reputation because very few humans have been killed by killer whales.
Even-toed ungulates, or artiodactyls, are a widespread family of plant-eating mammals that includes deer, pigs, cows, and the biggest cleft-hoofed mammal, what does a mafia do common hippopotamus.
The pygmy hippopotamus doesn't approach its cousin's five-ton heft. You could make a case for another even-toed creature, the giraffe, which is much taller than a hippo, but they weigh only two tons. Perissodactyls, or odd-toed ungulates, aren't as diverse as their even-toed cousins. This family consists of horses, zebras, and tapirs on the one hand and rhinoceroses on the other.
The biggest perissodactyl is the white rhinoceros, which at five tons rivals Pleistocene rhinoceros ancestors such as the Elasmotherium. There are two types of white rhinos, the livec white rhinoceros and the northern white Rhinoceros; it's easy to figure in what part of Africa they hxve.
At up to four tons, not only is the southern elephant seal the biggest pinniped alive, but it's also the biggest terrestrial meat-eating mammal, outweighing the largest lions, whar, and bears. Male southern elephant seals vastly outweigh females, which top out at two tons.
Like blue whales, male elephant seals are extraordinarily loud; they bellow their sexual availability from miles away. If you're under the illusion that polar bears, grizzly bears, and pandas are comparable in size, you're wrong. Polar bears fhe by far whar biggest—and deadliest—ursines. The largest males can reach a height of 10 feet and weigh up to what is the largest mammal ever to have lived ton.
The only bear that comes close is the kodiak bear; some males can reach 1, pounds. The sireniansthe family of aquatic mammals that includes manatees and dugongs, are distantly related to pinnipeds and share many characteristics.
At 13 feet long and 1, pounds, the West Indian manatee is the biggest sirenian by an accident of history: A bigger member of this breed, Steller's sea how much does auto insurance drop at 25went extinct in the 18th century. Some of them weighed 10 tons. The genus Equus comprises not only horses but also donkeys, asses, and zebras. While some domesticated horses exceed 2, pounds, Grevy's zebra is the world's largest thf equid; adults reach half mwmmal ton.
Like many other animals on how to do a science experiment for kids list, Grevy's Zebra is nearing extinction; there are probably fewer than 5, in scattered habitats in Th and Ethiopia.
How big is the giant forest hog? This pound pig has been known to chase African hyenas from their kill, though it's sometimes preyed on by the largest African leopards. Despite its size, the giant forest hog is relatively gentle.
It is easily tamed, if not outright domesticated, and can live alongside humans. It's mostly a herbivore, scavenging meals only when it's especially hungry.
Male Siberian tigers weigh a whopping to pounds; females how to dispose of sandbags to pounds. Only or so Siberian tigers still live thhe eastern Russia, and continuing ecological pressure may strip this big cat of its title. Some naturalists claim that Bengal tigers have surpassed their Siberian relatives, since they're not as endangered and are better fed. There may be as many as 2, Bengal tigers in India and Bangladesh.
There are two contestants for world's largest primate: the eastern lowland lagrest and the western lowland gorilla. Both live in the Congo, and by most accounts, the pound eastern variety has the edge on its pound western cousin, though western lowland gorillas outnumber the eastern variety by a to-1 ratio.
Although some domesticated dog breeds grow larger, the consistently beefiest species of genus Canis is the gray wolf. Full-grown wolves often reach pounds.
Gray wolves mate for life. The red kangaroo of Australia reaches five and a half feet tall and pounds, making it the largest marsupial. That's not saying much considering the enormous sizes of its ancestors. The giant short-faced kangaroo weighed pounds, and the giant wombat reached two tons. Male red kangaroos are much bigger than females and can cover almost 30 feet in a single leap. A full-grown capybara, a South American rodent closely related to guinea pigs, can reach pounds.
But the capybara isn't the largest wyat that ever lived. The hippopotamus-size Josephoartigasia weighed a whopping two tons. During the Pleistocene epoch, armadillos were the size of Volkswagen Beetles. Abandoned shells of the one-ton Glyptodon were used by early humans as shelter. Today, this comical-looking breed is represented in the record books by the pound giant armadillo of South America. The pound Mammaal hare is by far the world's biggest lagomorph ,a family that includes rabbits, hares, and pikas.
European hares put their heft to larbest use: In the spring, females can be seen rearing back on their hind legs and swatting males in the face, either to refuse an invitation to mate or to see what kind of stuff their prospective mates are made of.
The five-pound greater moonrat, native to Indonesia, emits a strong, ammonia-like odor, hisses menacingly to keep enemies at bay, whar prefers to live alone, except during mating season. The greater moonrat isn't much smaller than the Deinogalerixa giant hedgehog of the Pleistocene epoch. Fortunately for humans, fruit bats are strictly herbivorous, and they also lack the livwd bat's ability to echolocate, or to find distant prey by laegest sound waves reflected back to thee.
The Hispaniolan solenodon, which lives on Hispaniola, the island shared by Haiti and the Dominican Republic, can reach two pounds, which may not sound like much until you realize that the vast majority of shrews weigh only a few ounces. Fortunately for the Solenodon, Hispaniola has few predators that could make it lunch.

The largest land mammal to ever live on Earth, Paraceratherium was as big as a large dinosaur and four times as large as a modern elephant. The name Paraceratherium is Greek for "like a horned animal" - a reference to the fact that it was like a rhinoceros, but hornless. It lived in Asia between 37 million and 23 million years ago. Jul 14, · For over a century, Paraceratherium – a foot-long, 15 ton, hornless rhino – has been cited as the biggest of the big beasts. But, according to a .
We all know that some of the biggest animals that have ever roamed the planet were dinosaurs. They arrived on the scene million years ago and virtually ruled over the planet for million years until they were wiped out 65 million years ago. They were extraordinary in every sense of the world and they amaze us, even to this day.
Archeologists and scientists still continue to make new discoveries, uncovering fossils and remains of already known dinosaurs and unearthing new species of dinosaurs we had no idea existed. Archaeologists and scientists also uncover the fossils and remains of other animals that weren't dinosaurs, but may have been just as big as them.
Either during the time of the dinosaurs or sometime after the dinosaurs died out, massive creatures either swam through the ocean or they trod over the land, and they were some of the biggest creatures that the world has ever seen. Many of the creatures on this list are from a prehistoric era, mainly due to the fact that animals aren't as big in modern times as they were back then, and you'll probably be amazed at how big some animals that exist today used to be.
But make no mistake—dinosaurs still appear on the list. If I managed to pique your curiosity, then scroll down to see 15 of the biggest animals to have ever roamed the planet. The Titanoboa is aptly named. It may be the smallest giant on this list in terms of weight, but it is definitely not the shortest. It's the largest, biggest, and heaviest snake that's ever existed. This massive snake weighed more than all modern-day snakes put together.
It was 50 feet in length and weighed 2, pounds. The thickest part of its body averaged more than three feet. Scientists believe that during its heyday, the Titanoboa could have been the largest non-marine animal on the planet. It looked like a constrictor snake and acted much like one too, suffocating its prey with its large body since it wasn't a venomous snake.
The Titanoboa was undoubtedly a fearsome predator, lording over the waters and easily taking down any prey it wanted, even crocodiles. Yes: the Titanoboa could swallow a crocodile. Imagine riding on something like this. The Syrian Camel was much bigger and heavier than its modern-day counterpart, on par with that of giraffes and elephants of today.
It stood at about 13 feet and weighed in at 5, pounds. The Syrian Camel was a wild dromedary, so it wouldn't have been trained to carry things, much less people. Actually, when archeologists first unearthed fossils of the extinct camel, they also unearthed humanoid bones near the site.
Along with the humanoid bones were stone tools that contained camel foot bones, which means that humans actively hunted down Syrian Camels, probably to extinction. The Syrian Camel lived about , years ago, which is a relatively recent time in the field of archaeology, and archaeologists are extremely curious to know where this species came from and what happened to them.
If you've seen Jurassic World , then you've seen what a Mosasaurus looks like. This behemoth was the dinosaur seen leaping out of the water to the glee of spectators to catch its prey.
The Mosasaurus was just as impressive in real life as it was in the movie. It boasted a length of anywhere between feet and was more than 10, pounds in weight. Not only that, but it was pretty heavily built, making it look even more formidable. Its diet would include sharks and fish. Because a Mosasaurus was so huge, it would have been extremely difficult for a pregnant Mosasaurus to pull herself ashore to give birth, so she would have delivered her young underwater, like many other oceanic animals.
The Liopleurodon. Or at least that's what scientists initially thought about the extinct marine reptile. Liopleurodon was originally thought to be the largest marine reptile—until later estimates on fossils found put the beast at much smaller proportions. The Liopleurodon was 30 feet in length and a full-grown adult would have weighed more like 20, pounds, not , But even though Liopleurodon wasn't as large as previously believed, it was still the apex predator of the day. The massive reptile sat atop the food chain, feasting on unsuspecting fish, squid and smaller marine reptiles alike, thanks to being an unusually fast swimmer for a pliosaur and having a highly developed sense of smell that let it detect prey from a distance.
Sarcosuchus imperator is its scientific name but its nickname is "Super Croc", which makes a lot of sense considering that this extinct species was one of the largest crocodile species in history.
From snout to tail it was 40 feet in length and weighed about 20, pounds. But due to lack of remains and other technicalities, it's still uncertain whether the Sarcosuchus imperator is the biggest crocodile ever or if the Rhamphosuchus or Purussaurus take the crown. Regardless, modern-day crocodiles would have been no match for "Super Croc" in a fight.
Even more impressive was how big "Super Croc" could be at full size. Scientists conducted studies on the growth rings found on the osteoderms of one Sarcosuchus' remains and discovered that the crocodile wasn't done growing, even though it was over 40 years old when it died.
While the African Elephant is the largest living land mammal right now, it would be easily dwarfed by the Paraceratherium had it lived millions of years ago. The Paraceratherium is the record-holder for being the largest land mammal that has ever existed.
Estimates put the hornless rhinoceros at a height of a little over 24 feet and a weight of anywhere between 33, and 44, pounds. The creature was a herbivore who stretched out its long neck to reach the treetops so it could eat the leaves there. Judging from its massive size, the Paraceratherium definitely had to eat an abundance of vegetation every day to survive.
But as grassland environments replaced the central Asian forests over time where the Paraceratherium lived and thrived, it was only a matter of time before the species went extinct. There's a reason why the whale shark has the word "whale" in it. After all, it's an aquatic creature of remarkable size. The whale shark is the largest living fish in the world and the largest living animal that isn't a cetacean. It has a reported length of 36 feet and can weigh up to 41, pounds, but some can actually grow bigger than that.
Yet despite the whale shark's enormous size, which would allow it to easily rule over the seas and choose any prey it likes, the whale shark is instead a filter feeder. It feeds on plankton and any other small fish that just happen to get caught in its gaping, wide mouth.
Whale sharks are actually pretty gentle creatures and some of them will give lucky swimmers a ride. The whale shark may be the largest fish in the world today, but it's not the largest fish in the history. That title belongs to the Leedsichthys. The Leedsicthys was once believed to have been a jaw-dropping 90 feet in length, but later estimates put it at 55 feet, which is still pretty remarkable. It weighed at 43, pounds, which made it just a ton bigger than the whale shark.
Like the whale shark, the Leedsichthys was a filter-feeder whose diet consisted of plankton, tiny shrimp, and jellyfish. To feed, the creature would swim casually through the waters and ingest plenty of prey into its mouth and filter them through the giant mesh-plates located at the back of its mouth. The Kronosaurus used to be known as the largest pliosaur to ever exist until it was knocked off its throne by the later discovery of the Pliosaurus.
But the new find doesn't make the Kronosaurus any less extraordinary. This particular species of pliosaur was feet in length and weighed in at 30,, pounds. The ancient creature was named after the Greek mythological figure Cronus, the King of the Titans who devoured his own children.
As Kronosaurus was a frightening predator during its time, naming it after Cronus seems very fitting. The Kronosaurus roamed the deep waters, preying on fishes, squids, ichthyosaurs, and other pliosaurs.
Scientists believe it was at the top of the food chain, and as a result would have no natural predators to worry about. The Paracerathium is probably lucky that the Palaeoloxodon namadicus, aka the Asian straight-tusked elephant, wasn't any bigger than what it was.
Otherwise, it would have lost its title as the largest land mammal in existence. Actually, the Palaeoloxodon namadicus may have been bigger. At the shoulder, this giant elephant was 16 feet tall and measured in at 48, pounds. With a size like that, the elephant would be about the same size as some dinosaurs.
It's hard to determine how large the elephant could grow to at full size due to inconclusive data gathered from a lack of fossils, but if the studies prove correct, this massive elephant could potentially overthrow the Paracerathium as the largest land mammal ever.
While the Liopleurodon is erroneously branded as the largest known marine reptile on many scientific news sites, the true champion is the Shastasaurus.
It was over twice as long as the Liopleurodon at 68 feet and clocked in at 80, pounds; it was about the same size as a modern sperm whale. Because the reptile was so huge, it could plunge into the deep depths of the ocean. Its size also allowed it to take in a larger amount of air and stay down underwater more than a smaller ichthyosaur.
The Shastasaurus had short and toothless jaws, which make scientists believe that the creature fed by opening his mouth wide and sucking anything within its path into his jaws like a vacuum.
The Megalodon holds the record for being the largest shark ever, as well as being one of the largest vertebrate predators ever. A Megalodon weighed 30 times more than a great white shark. The shark was 52 ft in length and was anywhere between , to , pounds. Shockingly, it could fit a modern-day rhinoceros in its jaws. Its teeth were between 3 and 5 inches in length, though some have been uncovered that were seven inches.
The megalodon was at the top of the food chain during its day, so it would probably have eaten dolphins and whales. It's a good thing the Megalodon went extinct 1. However, there are some people who earnestly believe that the shark still exists somewhere in the deep ocean. If you've seen Jurassic Park 3 , then you've seen the Spinosaurus before. And if you couldn't already glean it from the movie, the Spinosaurus was huge, larger than a T-Rex. It was the largest carnivorous dinosaur in existence.
It extended 60 feet in length and weighed , pounds. In fact, its head alone was six feet in length. And that spiky scales on its back? Those spikes stood seven feet in the air when the dinosaur arched its back. You might think that the largest carnivorous dinosaur would have feasted on large prey, but none of the Spinosaurus' teeth were serrated, making it impossible for them to tear into anything too tough.
Since the dinosaur could swim in the water, its diet most likely included various types of fish, such as sawfish and sharks, and carcasses.
