Glires are a class of mammals with rootless incisors that grow throughout their lives. These mammals are thought to have grown from Eutherian and are composed of rodents and lagomorphs. Like other insectivorous, Glires walk on fours and can be fast-moving with an excellent sense of hearing and smell. Most of these animals are herbivorous while others like rodents can be scavengers. They inhabit many terrestrial environments with the hares living in bushes or forests while their cousins the rabbit being domesticated. These animals like Eulipotyphla live in solitary, have claws, and strong limbs for digging tunnels and bodies covered in fur.

When did lagomorphs and rodents diverge?

It is believed that Lagomorphs and rodents diverged about 64.5 million years ago. Lagomorphs and rodents diverged at the start of the Tertiary time period and at the end of the Cretaceous time period. Their divergence happened as a response reaction to global environmental change.

Do rabbits and rodents have a common ancestor?

It is believed that rabbits and rodents have a common ancestor which is why they share similar characteristics and physical traits. Some of those similar traits have been lost in some lineages while they have been retained within others. Although they do share a common ancestor it is not known who the common ancestor was.

Is a rabbit a rodent?

The rabbit is not a rodent and is not part of the Rodentia group of mammals, although they are often confused. Rabbits are differentiated from rodents by their extra pair of incisors directly located one behind the other as well as other skeletal features. Rabbits and hares are part of the group Lagomorpha.

Yellow-Bellied Marmot
Dimensioned size comparison illustration of the Yellow-Bellied Marmot compared to an average person

The Yellow-Bellied Marmot, also called the whistle pig or rock chuck, is a medium-sized rodent that uses the rocky areas of Canada and the western United States for safety and burrowing. Scientifically identified as Marmota flaviventris, the Yellow-Bellied Marmot gets its name from the yellow fur that can be found on its belly. The rest of its coat consists of brown fur with white spots and patches around its eyes.

The Yellow-Bellied Marmot typically lives in colonies consisting of up to twenty individuals, all of which spend their time residing in their burrows situated on hills or cliffsides. The significant time spent in burrows is also due to hibernation.

Yellow-Bellied Marmots have a height of 9.4”-13.4” (24-34 cm), body length between 18.5”-27.5” (47-70 cm), and an overall weight in the range of 3.5-11 lb (1.6-5 kg). The tail length of a Yellow-Bellied Marmot is 5.1”-8.7” (13-22 cm). Yellow-Bellied Marmots have a typical lifespan of 12-15 years in the wild and up to 21 years in captivity.

Guinea Pig | Cavy

Originating from the Andes of South America, the American Guinea Pig is considered the oldest, most popular Guinea Pig (or Cavy) breed. Today, the American Guinea Pig is commonly kept as a pet although it was originally raised as livestock in its native country. Its scientific name is Cavia porcellus, with porcellus meaning “little pig” in Latin.

Considered one of the larger-sized rodents weighing up to three pounds (48 ounces), the American Guinea Pig is physically characterized by its stout body, short, flat coat appearing in a variety of colors, rounded nose, and the absence of a tail.

Guinea Pigs have a height of 3.3”-4.1” (8.5-10.5 cm), body length between 7.9”-9.8” (20-25 cm), and an overall weight in the range of 1.5-2.6 lb (.7-1.2 kg). Guinea Pigs have a typical lifespan of 2-4 years in the wild and 5-7 years when raised in captivity.

Norway Lemming

The Norway Lemming, scientifically known as Lemmus lemmus, is a rodent inhabiting the Arctic tundras. Its coat, unlike that of other rodents, can be quite noticeable in appearance: gray with reddish-brown stripes or tawny and black. Other physical characteristics include short legs and stump of a tail as well as a round body and nose.

The shape of a Norway Lemming’s claws help it burrow into the snow-- a necessary action in the winter for protection as it does not hibernate. In the spring however, the lemming moves from the tundra to higher areas. Lemmings are known to reproduce at rapid rates, leading to aggressive population fluctuations.

Norway Lemmings have a height of 2.2”-2.6” (5.5-6.5 cm), body length between 5.1”-6.3” (13-16 cm), and an overall weight in the range of 2.5-4.6 oz (70-130 g). The tail length of a Norway Lemming is .4”-.75” (10-19 mm). Norway Lemmings have a typical lifespan of 1-2 years in the wild and 2-3 years in captivity.

Eastern Chipmunk

The Eastern Chipmunk (Tamias striatus) is a ground squirrel native to and residing in deciduous forests of eastern North America. It can also be spotted around urban parks or rocky areas with shrub cover. The Eastern Chipmunk is small and has pouched cheeks for storing and carrying food.

It is distinguished by both light and dark brown stripes running along its body with a lighter underbelly and darker tail. Although it does not go into hibernation, the Eastern Chipmunk will sleep for long periods of time and wake every so often to consume the food kept in its burrow.

Eastern Chipmunks have a height of 1.6”-2.4” (4-6 cm), body length between 3”-4.5” (7.6-11.4 cm), and an overall weight in the range of .14-.33 lb (65-150 g). The tail length of an Eastern Chipmunk is 2.75”-4.3” (7-11 cm). Eastern Chipmunks have a typical lifespan of 2-4 years in the wild and 6-8 years in captivity.

Lowland Paca
Dimensioned size comparison illustration of the Lowland Paca compared to an average person

Also known as the spotted paca, the Lowland Paca is a rodent native to the subtropical regions of North and South America. Scientifically known as Cuniculus paca, the Lowland Paca gets its secondary name from its physical appearance: a dark brown coat with rows of white spots running down its sides.

Other physical characteristics include: a large head, short thick legs, and a seemingly nonexistent or nub of a tail. The Lowland Paca is noted to be skillful diggers, swimmers, and climbers. It builds bankside burrows, avoids danger by submerging into the water, and can gather fruits from trees.

Lowland Pacas have a height of 11”-14.6” (28-37 cm), body length between 23.6”-31.5” (60-80 cm), and an overall weight in the range of 13-31 lb (6-14 kg). The tail length of a Lowland Paca is 5.1”-9” (13-23 cm). Lowland Pacas have a typical lifespan of up to 12 years in the wild and between 12-16 years in captivity.
