Giant Rodent In The World

5 Giant Rodent In The World

When you hear the word “rodents,” you probably think of little, fluffy mice that might fit in the palm of your hand. With the exception of city rats that become the giant rodent on a diet of abandoned food, people rarely image rodents as enormous, threatening creatures. Rats and mice, on the other hand, are far from the most stunning rodents.

1. Capybara (Hydrochoerus hydrochaeris)


The capybara is now thought to be the world’s biggest living rodent. This rat lives in semi-aquatic environments and is an adept swimmer. Grass, fruit, and other water plants make up their diet. They’ve also been known to wreak havoc on indigenous peoples’ gardens and farms.

Capybaras, while shy when confronted by other species, are very social with one another. They generally live in groups, with the occasional solitary male striking out on his own.

  • Weight: 77 – 150 pounds
  • Length: 4.4 feet in length and can reach up to 24 inches tall.
  • Habitat: Rivers and wetlands of Central and South America
  • Diet: Herbivorous

2. North American Beaver (Castor canadensis)

North American Beaver

The North American beaver has an impressively lengthy body, making it one of the world’s biggest rodents. Its large, flat tail also allows it to easily swim through the water. This aids the Native American beaver in navigating rivers and other bodies of water, where it spends the majority of its time. One of the most impressive skills of the North American beaver is controlling its environment by building dams.

Their strong front teeth serve as chisels in the cutting of wood that are later used to stop rivers. Following the construction of these dams, beavers build semi-flooded shelters known as lodges in which they dwell and raise their young.

  • Weight: 24 – 71 pounds
  • Length: 3 feet long. Their tail can grow up to 14 inches long.
  • Habitat: Forests and rivers in North America and Canada
  • Diet: Herbivorous

3. Cape Porcupine (Hystrix africaeaustralis)

Cape Porcupine

The Cape Porcupine is now Africa’s biggest extant rodent species. Not only that, but it is the world’s biggest porcupine. They may be found in a variety of settings, ranging from barren deserts to lush forests. These rodents are known to dig chambers in grassy regions to establish birthing dens in savannah terrains.

In the wild, Cape Porcupines typically live for around 15 years, which is very lengthy for a rodent. They eat largely plant materials such roots, fruits, tubers, bark, and bulbs.

  • Weight: 33 pounds
  • Length: 2.1 to 2.7 feet, while its tail can grow around 4 to 8 inches long.
  • Habitat: Forests and deserts of Southern and Central Africa
  • Diet: Omnivorous

4. Nutria (Myocastor coypus)


The nutria is a burrowing, semi-aquatic, herbivorous rodent. It is assumed to be South American in origin, although it may also be found in North America, Asia, and Europe. They are said to have spread over the planet by stowing away on exploratory ships. They have the appearance of enormous rats and can infest rural farm regions. The nutria was a big annoyance to farm owners in England and the United States, notably in Maryland and Louisiana, in the 1940s. By the 1960s, laws had been enacted to exterminate the nutria rodents..

While sometimes nicknamed the South American Beaver, the Nutria’s resemblance is only superficial. Nutria have thin tails, more similar to the tails of rats. This detail can be easily overlooked when the Nutria are sighted in the water, leading to frequent misidentification.

  • Weight: 15 – 22 pounds
  • Length: 2.3 to 3.5 feet.
  • Habitat: Rivers and wetlands of South America
  • Diet: Omnivorous

5. Muskrat (Ondatra zibethicus)


The muskrat is a semi-aquatic rodent that is called “medium-sized,” despite the fact that it may become fairly large in adulthood. These rodents contribute significantly to their ecosystems by providing a consistent source of food for natural predators such as minks, eagles, and otters. They are also a source of fur and food for humans.

  • Weight: 1 – 4.4 pounds
  • Length: 1.3 to 2.3 feet in length.
  • Habitat: Rivers and wetlands of North America, South America, Asia, and Europe.
  • Diet: Omnivorous
