Top 10 biggest animals on earth

of reading

The largest animals living on Earth today are not land animals, because on land they have to fight against the forces of gravity to survive, which effectively limits their size. Ocean creatures can grow much larger, as the buoyancy of water allows them to break free from the effects of gravity, giving them the freedom to grow to gigantic proportions. The largest animal that has ever existed lives in the sea. All species have a larger limb. The list below shows each of these largest animals on earth today.

The largest animal ever: the blue whale (Balaenoptera musculus)


The largest animal that has ever lived on Earth is the adult blue whale. These animals are larger than any dinosaur that has ever lived, and they are much larger than the largest land animal living on the planet today. Blue whales can grow up to 32 meters long. That's more than twice as long as a semi-truck driving down the highway. An adult blue whale weighs as much as 15 school buses. Discover our Giant Whale Plushies!

The largest bird: The ostrich (Struthio camelus)

The largest bird on Earth is the ostrich. Too big and too heavy to fly, this bird is capable of running at speeds of up to 43 MPH (70 km/h) over long distances. Males can grow to more than 2.8 m (6 ft) tall and weigh up to 156.8 kg (500 lbs), the equivalent of two people. Females are generally smaller and rarely exceed 2 m in height.

The largest reptile: the saltwater crocodile (Crocodylus porosus)

The largest reptile in the world is the saltwater crocodile, with males reaching up to 6.1 m in length and weighing 1,075 kg, about twice the weight of a grizzly bear. Females are much smaller and rarely exceed 3 m in length. Discover our Giant Crocodile Plushies !

The largest mammal: the blue whale (Balaenoptera musculus)

The adult blue whale is larger than three prehistoric triceratops and holds the record for the largest mammal on Earth. Other whale species come close in size. The largest living land animal, however, is the African elephant (Loxodonta Africana). This mammal is usually 3 to 4 meters tall and can weigh up to 8,000 kg.

The largest amphibian: The Chinese giant salamander (Andrias davidianus)


The Chinese giant salamander lives its entire life underwater, but has no gills. Instead, it absorbs oxygen through its skin. This strange-looking creature grows quite large, up to 180 cm, and weighs 70 kg, the size of many adult humans. When it comes to reproduction, females lay up to 500 eggs and males take care of the young until they hatch. Discover our Giant Salamander Plush!

The largest rodent: Capybara (Hydrochoerus hydrochaeris)

The capybara looks a lot like a giant guinea pig, but instead of being hand-held, this huge rodent is 0.61 m tall at the shoulders and 1.4 m long. Twice the size of an adult beaver, capybara can weigh up to 65 kg. They live in herds of about 40 animals, and males and females are about the same size.

Largest snake: Giant Anaconda (Eunectes murinus)

For total mass, the largest snake in the world is the giant anaconda. This huge animal can weigh up to 250 kg, and some individuals can measure up to 9.1 m long. That's longer than a double-decker bus in London. They can be up to 3 feet tall in the middle, giving them plenty of room to swallow all kinds of prey, including mammals as large as deer, fish, alligators, birds and anything else they can catch.

The largest lizard: The Komodo dragon (Varanus komodoensis)

The largest lizard on Earth is the Komodo dragon. This dangerous animal can grow up to 3 meters long and usually weighs 91 kg. Females tend to be smaller than males and usually do not exceed 1.8 meters in length, which is about the size of an average human. These lizards hunt large prey such as water buffalo, pigs and deer, and have even been known to chase people.

The largest arthropod: Japanese spider crab (Macrocheira kaempferi)

The arthropod family includes lobsters and crabs, spiders, scorpions, insects and other creatures with jointed exoskeletons. The largest arthropod listed is the Japanese spider crab. One of these was captured in 1921. It measured 3.8 m in diameter and weighed 19 kg. This is almost the same length as a Volkswagen Beetle car.

The largest insect: the Titan beetle (Titanus giganteus)


Titan beetles are sometimes mistaken for a form of cockroach, but these huge South American insects are a species apart. They can grow up to 16.7 cm long and weigh 100 grams. They have strong mandibles that can break a pencil and sharp claws that they use for defensive purposes. No one knows what their larvae look like because they have never been seen.
