25 Largest Animals on Earth

Posted by on March 4, 2013

Although man may be responsible for some of the changes that the Earth is now undergoing, when it comes to physical size, humans are nowhere near being the largest creatures on the planet. While you may think to yourself that of course there are fishes, primates, and other animals that are a lot bigger than humans, in this list we’re going to see some creatures that are larger than trees, boats, and even houses. So get ready because these are the 25 largest animals on Earth.


Ocean Sunfish

Spanning up to 4 meters the Ocean Sunfish is not only famous for being huge and heavy but also for its interesting shape. Its prey consists mainly of jellyfish…lots and lots of jellyfish.



Also known as the Indian bison the Gaur is much larger than its American counterparts, especially when you count the hump protruding from its back.


American Alligator

If you live in the southeastern United States then you are already familiar with the big toothy grin of the American Alligator. Although it doesn’t usually prey on humans, its definitely big enough to do so, and will occasionally exercise that ability. Normally though its diet consist of small animals, birds, and other marsh dwellers.


Elephas Recki

Although long extinct, standing at up to 15 feet in height this was at one point the tallest elephant species in the world. It’s probably safe to assume that its diet consisted of more than just peanuts!


White Rhinoceros

A bit smaller than the hippopotamus (#19), the White Rhinoceros has long been the target of African poachers seeking its horn, which is said to cure illnesses and as of today it is one of only 5 rhinoceros species still in existence.


Chinese Rat Snake

Named after their ferocious appetite, which not surprisingly consists mostly of rats, these brightly colored behemoths can grow to nearly 5 meters in length.



Belonging to the triad of largest land mammals in the world together with the elephant and the rhinoceros, hippos are semi-aquatic creatures that spend most of their time partially submerged in water holes. Don’t let this fool you though. Like icebergs, most of their mass is hidden and if you manage to upset one of them…run. They’re notoriously fast.


Bluntnose Sixgill Shark

Also known as the cow shark it can grow to be over 5 meters long. It is actually the largest of its subspecies although this is probably partially due to the fact that most of its closest relatives are extinct.


Tiger Shark

Last time it was cow sharks, now its tiger sharks. Growing slightly larger than their counterparts they can be nearly 6 meters long and typically feed on birds, turtles, seals, and even dolphins.


King Cobra

Growing to nearly 6 meters in length it’s the largest venomous snake in the world. The name seems appropriate.



Undoubtedly the tallest living creature in the world, a giraffe can reach food sources nearly 6 meters off the ground.


Nile Crocodile

You’ve probably noticed that this list is heavily populated with sharped toothed reptiles and we are here to reinforce that notion. The Nile crocodile is often said to be the second largest crocodilian in the world after the saltwater crocodile.


Great White Shark

One of the most feared predators in the world thanks to Hollywood, Great Whites can grow to be over 6 meters long and yes, they have been known to attack humans, boats, and basically anything else that floats.


Saltwater Crocodile

Growing to be over 6 meters long, this breed of crocodile is as big as it gets…and as dangerous too.


Southern Elephant Seal

Though seals may look cute in the magazines the Southern Elephant Seal seal may not be the cuddliest creature in the world, especially if you consider that the fact that it’s almost exclusively carnivorous.
