Some rodents are enormous \u2013\u00a0like the cat-sized Indian giant squirrel \u2013 while others have impressive adaptations, from star-shaped tentacled noses to webbed feet.<\/p>\n
One even holds the title for the most mating sessions in the animal kingdom. Whether they fly, swim or even defy ageing itself, these unusual rodents are anything but ordinary.<\/p>\n
Weirdest rodents in the world<\/h2>\n
Indian giant squirrel\u00a0<\/em>(Ratufa indica<\/em>)<\/h3>\n
Better known as the ‘rainbow squirrel’, the Indian giant squirrel (or Malabar giant squirrel) is unusual both forr its size and (you guessed it) its rainbow-like multi-coloured colouring.<\/p>\n
Weighing four times as much as a\u00a0grey squirrel, the rainbow squirrel is about the same size as a domesticated cat.<\/p>\n\n

Star-shaped nose mole (Condylura cristata<\/em>)<\/h3>\n
As with the rainbow squirrel, the\u00a0star-shaped nose mole’s name speaks for itself. This hamster-sized rodent has a tentacled snout that is super sensitive, packed with nearly 50 per cent more sensory adaptors than the human hand. It can identify anything it touches seven times faster than a human can blink, which makes it the most sensitive organ in the animal kingdom.<\/p>\n
We named the star-shaped nose mole in our round-up of\u00a0blind animals that can survive in complete darkness\u00a0and the\u00a0world’s weirdest animals.<\/p>\n\n

Gunnison’s prairie dog (Cynomys gunnisoni<\/em>)<\/h3>\n
Despite its name, the\u00a0Gunnison’s prairie dog is not a member of the canine family \u2013 it’s actually considered to be a rodent. However, they take their name from the sound they make, which is said to sound like a dog bark.<\/p>\n\n

One of the\u00a0weirdest rats in the world\u00a0the\u00a0naked male-rat\u00a0is the world\u2019s only cold-blooded mammal and can survive 18 minutes without oxygen and feel no pain. They also live like insects, with colonies ruled by a single breeding queen which produces dozens of offspring several times a year. Fascinatingly, the\u00a0naked mole rat also defies ageing and disease. While mice live to around four years of age, naked mole rats can live up to 30, remaining fertile until the end.<\/p>\n
We named the naked mole rat as one of the\u00a0weirdest animals in the world.<\/p>\n\n

Surprisingly, the ezo flying squirrel is just one of about 44 species of\u00a0flying squirrels\u00a0worldwide, so this really is just the beginning.<\/p>\n\n

Shaw’s jird (Meriones shawi<\/em>)<\/h3>\n
This North African desert rodent was observed mating 224 times in two hours, making it one of the\u00a0animals that has the most sex.<\/p>\n\n
The\u00a0capybara\u00a0is the largest rodent, and although they live in social groups, they’re also welcoming of other species. It’s not uncommon to see capybaras with birds perching on their backs. They’re consdered unique because of their semi-aquatic lifestyle, spending much more of their time in water than other rodents. Because of this, they have developed adaptations such as webbed feet, nostrils, eyes and ears located high on their heads so they can look out for predators while they’re submerged.<\/p>\n
Fun fact: they also eat their own dung, in order to extract maximum nutrition (time and again) from their food).<\/p>\n\n

The maned rat \u2013 which also goes by the name of the crested rat (or the African crested rat) \u2013 is considered to be the only\u00a0poisonous rat. It\u2019s also the only known mammal to sequest plant toxins for use as a defence mechanism.<\/p>\n

Despite only measuring 15cm from nose to tip of tail, the Southern grasshopper mouse is one of the deadliest rodents in the world \u2013 remarkably fearless, these mice are aggressive hunters.<\/figcaption><\/figure><\/figure>\n
It is largely immune to the venom of the Arizona bark scorpion (Centruroides sculpturatus<\/em>) and will even turn to cannibalism when food is scarce.<\/p>\n
