Rodents
Rodents are a diverse group of mammals that belong to the order Rodentia. They are characterized by a single pair of continuously growing incisors in the upper and lower jaws, which must be kept short by gnawing. This group includes animals such as mice, rats, squirrels, beavers, and capybaras.
Characteristics of Rodents
- Single pair of continuously growing incisors
- Well-developed jaw muscles for gnawing
- Mostly herbivorous, but some are omnivorous
- Adapted to various habitats, including terrestrial, arboreal, and aquatic
Ecological and Economic Importance
Rodents play a key role in various ecosystems as seed dispersers, soil aerators, and food sources for predators. However, they can also be agricultural pests and vectors of diseases such as hantavirus and Lyme disease.
Common Rodent Species
- House mouse (Mus musculus)
- Norway rat (Rattus norvegicus)
- Eastern gray squirrel (Sciurus carolinensis)
- Beaver (Castor canadensis)
- Capybara (Hydrochoerus hydrochaeris)
