What Is a Rodent?

A rodent is a small, gnawing mammal of the order Rodentia notable for its constantly strong growing incisors and no canine teeth. These mammals are so great that they constitute about 40% of the population of mammals in the world. Most rodents have small robust bodies, short limbs, and long tails. They are endowed with sharp incisors to gnaw food, shovel burrows, and protect themselves from danger.

Over the years these creatures have appeared to serve useful purposes and also serve as a nuisance to mankind i.e pests/pets, theses useful purposes include: They could be served as food, their skin can be used in the sewing of cloth material, for laboratory research purposes, as pets and many lots more.

Rodents have seemed to be the largest most classified order of mammals as there are over thousands of rodents all over the world. Do you want to find out more? then, keep journeying!

Characteristics Of Rodents

  • Rodents have one pair of incisors each on the upper and lower jaw.
  • The incisors of rodents keep growing continuously.
  • There is a very large gap between the incisors of rodents.
  • Rodents lack the relatively sharp-pointed teeth usually found in humans, dogs, etc known as the canine teeth.
  • The incisors of these rodents usually wear down as they lack enamels on the back of their tooth.
  • Their forelimbs usually have 5 digits while their hindlimbs usually have digits ranging from 3-to-5 digits.
  • A majority of the specie move on both palms and feet which are heavily endowed with sharp claws.
  • Rodents use a wide variety of methods of locomotion including quadrupedal walking (using all four feet for walking), running, burrowing, climbing, bipedal hopping (using only two legs), swimming, and even gliding.
  • Most rodents have tails which help in balancing while running and locomotion (as in beavers).
  • Many of these species have long whiskers mainly for sensitivity.
  • Most species have a penis bone, the baculum.
  • Males are bigger than the females or the reverse is the case depending on the specie of rodent involved.


Rodent’s habitat

Another curtailing question is, where do these pets/pests live?

Well, the shocking answer is that rodents are found everywhere in the world except Antarctica.

  • Rodents can be found living in trees, examples of such rodents are the tree squirrel and the new world porcupines.
  • They can be found underground, examples of these burrowing rodents are the mole rats and the gophers.
  • What’s more amazing is they also live in water, that is, they are aquatic. An example of an aquatic rodent is the earless water rat. While some are semi-aquatic, examples of these rodents include the beavers, muskrats, etc.
  • Most commonly rodents are found even in human homes (the arctic, cupboard, wardrobe, roof, etc), farms, etc and serve as a great nuisance to our homes and farm crops.

Feeding in Rodents

Rodents feed on almost anything but not everything. Most rodents are herbivorous, that is they feed on plant parts (leaves, flowers, stem, seeds, and roots), some are omnivorous, that is they feed on both plants and animals and some are predators, that is they hunt other animals for food. Of course, you wouldn’t need to be told that they can’t hunt animals way bigger than them.

Herbivorous Rodents

The most popular species of herbivorous rodents are guinea pigs and chinchillas. Having them as pets would require feeding them commercial pellets, besides fruits and vegetables, and supplement their diet with high-quality hay. In the case of fresh food, it is advisable that only suitable types of vegetables and fruits are provided otherwise digestive problems may arise. Another measure that you can take is simply letting fresh forages sit and dry for a couple of hours after cutting them before feeding to the rodent.

Make sure that you feed guinea pigs with food specifically for them since that for mice, rabbits or rats don’t have the same level of vitamin C. You can also see to this need by providing them with green leafy vegetables and fruits.

But how about those who live in the wild. The field vole is a popularly known herbivorous rodent and feeds on grasses, moss, root tubers, herbs, etc it also gnaws on bark during the winter. Although it occasionally feeds on invertebrates such as insect larvae. The plains pocket gopher is another herbivorous rodent and feeds on plant parts found underground during burrowing, and also collects grasses, roots, and tubers in its cheeks and stores them underground.

Omnivorous Rodents

This means that this specie of rodents feeds on both plants and meat, examples include the rats, mice, and gerbils. These guys feed on insects and soft-bodied invertebrates, aquatic insects, fish, crustaceans, mussels, snails, frogs, birds’ eggs, and water birds. The grasshopper mouse from dry regions of North America feeds on insects, scorpions, and other small mice, and a small part of its diet is plant material. This rodent has a thick body with short legs and tail, but is agile and can easily overpower prey as large as itself. Amazing right?


Mating in Rodent

Rodent Mating

Most living things mate before reproduction, and the rodent is no exception.

Mating in rodents classifies them into 3 different types, which are the:

Monogamous Rodent

This specie of rodent carries out monogamous mating in which both male and female look after the offspring after mating (obligate monogamy) and essential care is given to the offsprings as the male is only attached to one female. In some other monogamous rodents, the male doesn’t have to directly care for the offspring and attach to one female (facultative monogamy) because of spatial dispersion. Examples of the rodents that practice monogamous mating are the  Oldfield mice, Malagasy giant rats, and beavers.

Polygynous Rodent

In polygynous mating, one male mates with multiple females but each female only mates with a single male. In this system, males tend to defend and mount areas where resources capable of attracting females are and when females have been attracted the males monopolize them and mate with them (defensive polygyny). Some other specie of polygynous rodents are not defensive and just wander around in search of females to monopolize and mate with. This occurs in some Tree Squirrels.

Promiscuity Rodent

In this system of mating both the male and the female rodent mate with multiple rodents. The female reproduces offsprings with multiple paternity.

The Intelligence of a Rodent

Rodent Intelligence

Rodents are very sensitive animals, as they can avoid poison baits, are capable of remembering pathways to a food source and can even locate a food source due to spatial memory.

This is known as cognitive ability and has made rodents serve as a means of research and learning purposes to human beings. Examples of these rodents are the Guinea pig, Brown rat, Kangaroo rat, etc The brown rat has the ability to consider its own learning and then make decisions based on what it knows. This makes them the first animals other than primates known to have this capacity, but these findings are disputed, since the rats may have been following simple operant conditioning principles or a behavioral economic model. Brown rats use social learning in a wide range of situations, but perhaps especially so in acquiring food preferences.
