In spite of their morphological and ecological variety, all rodents share just one characteristic: their dentition is highly specialized for gnawing.

This occurs in species like Belding's ground squirrels and several tree squirrel species.[sixty seven]
For the reason that laboratory mice (home mice) and rats (brown rats) are extensively employed as scientific types to more our knowledge of biology, an incredible deal has come to be identified with regards to their cognitive capacities. Brown rats exhibit cognitive bias, where information and facts processing is biased by whether or not they are in the favourable or detrimental affective state.[78] For example, laboratory rats properly trained to respond to a particular tone by pressing a lever to get a reward, also to press another lever in reaction to a special tone in order to avoid receiving An electrical shock, are more likely to reply to an intermediate tone by deciding on the reward lever if they have just been tickled (anything they delight in), indicating "a link amongst the instantly measured good affective point out and final decision building beneath uncertainty within an animal model."[79]

They have one particular pair of incisors in Every single jaw (upper and reduce) and a considerable gap (called a diastema) Found amongst their incisors and molars. The incisors of rodents improve repeatedly and therefore are maintained by constant use—grinding and gnawing wears away the tooth in order that is often sharp and continues to be the correct length.

Rodents could possibly be Energetic all yr or enter periods of dormancy or deep hibernation. Breeding time and frequency, length of gestation, and litter size vary widely, but two of essentially the most prolific are both equally related to humans. The brown rat (
Nepotistic species for instance home mice count on urine, feces and glandular secretions to recognize their kin. Rodents use scent marking in many social contexts together with inter- and intra-species communication, the marking of trails as well as institution of territories.
