One species, discovered in an extinct volcano in 2009 and informally known as the Bosavi woolly rat, is 2.7 feet (82cm) long and weighs 3.3 lb (1.5kg).
Since discovering this giant, Kristofer M.
Helgen of the Smithsonian Institution has been busy reviewing the giant woolly rats.

Which animal is the third largest rodent?

What is the name of the largest rodent?
What is the largest rat ever found?
Discovered: The Biggest Rat That Ever Lived. Here, the upper tooth rows of Timor’s extinct giant rat (left), the biggest rat that ever lived, compared with the skull of a black rat (right), one of the most common rats, weighing some 5 ounces (150 grams). The skull of the black rat shown here is 35 mm long.
Are rats aggressive?
Rodents who bite humans are also not displaying true aggressive behavior but rather, fear induced defensive behavior. Rats and mice differ in their social organization and use of aggressive behaviors. Male mice are territorial and do not tolerate unfamiliar males within their home range (or cage).

Are rats smart?
Rats can do both those things and more! Rats are extremely intelligent creatures, which makes training them a piece a cake. In fact, the reason why rats are used in scientific studies (think mazes) is to study behaviour since they have such high levels of emotional intelligence.

including; Leptospirosis or Weil’s disease, Salmonella, Listeria, Toxoplasma gondii and Hantavirus. Brown Rats can inflict a great amount of structural damage.

Are rats smarter than mice?
Most biologists, for example, assume that rats are smarter than mice. Scientists now challenge this belief. They compared mice and rats and found very similar levels of intelligence, a result that could have powerful implications for researchers studying complex behaviors and learning.
Is Jerry a mouse or rat?

Hanna gave the mouse’s original name as “Jinx”, while Barbera claimed the mouse went unnamed in his first appearance.
