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.

Muskrat

The Muskrat, or Ondatra zibethicus, is a rodent of medium size native to North America. It typically inhabits wetlands and marshes, marking its territory with musk-- a strong scented secretion from the glands. The Muskrat makes for an excellent swimmer (even swimming backwards), and to aid itself in this, is equipped with a long, flat tail covered in scales which leaves a trail on the ground when on land.

As the name suggests, the Muskrat resembles that of a large rat, with thick brown-black fur, small facial features, and tiny front feet for digging.

Muskrats have a height of 4.5”-6.7” (11.5-17 cm), body length between 10”-15” (25-38 cm), and an overall weight in the range of 1.5-4.5 lb (.7-2 kg). The tail length of a Muskrat is 7”-11” (18-28 cm). Muskrats have a typical lifespan of 2-4 years in the wild and up to 10 years in captivity.

Eastern Gray Squirrel

The Eastern Gray Squirrel (Sciurus carolinensis) is a tree squirrel that inhabits large areas of dense woodland ecosystems in the Eastern and Midwestern United States; the species construct dens in large tree branches within the hollows.

They are scatter-hoarders, and food is stored in numerous small caches for later recovery; these stashes are made up of a range of foods like tree bark, tree buds, berries, and many types of seeds and acorns. Physically, the Eastern Gray Squirrel has mostly gray fur, but there are brown variations. The underside is white, and it has a large and bushy tail.

Eastern Gray Squirrels have a height of 4.3”-5.5” (11-14 cm), body length between 8”-11” (20-28 cm), and an overall weight in the range of .9-1.3 lb (400-600 g). The tail length of an Eastern Gray Squirrel is 7.5”-9.8” (19-25 cm). Eastern Gray Squirrels have a typical lifespan of 6-12 years in the wild and up to 20 years in captivity.

Japanese Dwarf Flying Squirrel

Scientifically known as Pteromys momonga, the Japanese Dwarf Flying Squirrel is a medium-sized rodent that is active at night unlike the common squirrel. In actuality, flying squirrels glide rather than flies (like bats or birds) through membranes of fur connected from its front to its back legs.

The apanese Dwarf Flying Squirrel can maintain stability and maneuver itself through the air with both its limbs and tail. When landing, the flying squirrel comes down on its padded hind feet. Its gliding abilities in combination with its sole activity at night allow the flying squirrel to evade potential predators, utilizing its large eyes to see in the dark.

Japanese Dwarf Flying Squirrels have a height of 2.6”-4.3” (6.5-11 cm), body length between 5.5”-9” (14-23 cm), and an overall weight in the range of .3-.5 lb (150-220 g). The tail length of a Japanese Dwarf Flying Squirrel is 3.9”-5.5” (10-14 cm). Japanese Dwarf Flying Squirrels have a typical lifespan of 5-7 years in the wild and up to 10-19 years in captivity.

North American Beaver
Dimensioned size comparison illustration of the North American Beaver compared to an average person

Scientifically known as Castor canadensis and known best for its dam building, the North American Beaver is a semi-aquatic rodent physically distinguished by its broad, flat tail. It is identified as the largest rodent in North America and the second largest in the world just behind the capybara.

The purpose of dam building is to create a deep pond in which the beaver can establish its home. The dam is constructed across streams and consists of a pile of sticks with underwater entrances as the beaver is a skillful swimmer. The home or burrow is then made out of sticks and twigs as well.

North American Beavers have a height of 14.2”-16.9” (36-43 cm), body length between 29”-35” (74-89 cm), and an overall weight in the range of 25-75 lb (11.3-34 kg). The tail length of a North American Beaver is 7.9”-13.8” (20-35 cm). North American Beavers have a typical lifespan of 10-15 years in the wild and up to 15-25 years in captivity.

Mini Rex

The Mini Rex is a domestic breed of rabbits of a small size and are miniature version of the Rex Rabbit as their name implies. They have extremely dense fur that stands upright. Their fur color ranges from black to chocolate, or opal. It was bred in 1984 in Florida in the United States.

Mini Rexs have a calm and easy-going personality, but some can be aggressive. The mini rex should not be over-groomed and should never be bathed since it will damage their fur.

The Mini Rex has a shoulder height of 6”-7.5” (15.2-19 cm), body length between 10.5”-12.5” (26.7-31.8 cm), and an overall weight in the range of 3-4.25 lb (1.4-1.9 kg). The ears of a Mini Rex are 3”-3.5” (7.6-8.9 cm) in length. The typical lifespan of a Mini Rex is 9-10 years (captivity).
