Mammals | Mammalia

Mammals are a warm-blooded vertebrate class, Mammalia, and are found on every continent and in the oceans. Mammals are distinguished by the female mammary glands used to feed their young, having hair or fur, three middle ear bones, and a hinged jaw. Mammals diverged from reptiles and birds in the late Triassic, a fact which is known from studying the bones and skulls of Mammalian ancestors to see that the jaws of prehistoric reptiles became the ear bones of mammals today. One of the most adaptable animal classes on the planet, mammals utilize every possible form of transportation (walk, crawl, burrow, swim, climb, etc.) and may live solitarily or in groups for protection depending on the species.

When did mammals first appear?

Mammals first appeared during the Triassic period which was about 252 million to 201 million years ago and were members of the reptilian order Therapsida. This order had a subclass, Synapsida which are sometimes referred to as mammal-like reptiles. They were part of the Carboniferous period and are considered one of the earliest reptilian groups.

Which mammal species lay eggs?

The only 2 mammal species that lay eggs are the duck-billed platypus and the echidna, also known as the spiny anteater. The reasons these 2 mammals still lay eggs may be due to their distant ancestors as well as other primitive traits like their reptile-like shoulders.

What are the most common mammal species?

The most common mammal species are humans as it is the most numerous species of mammal on Earth. As of 2022, the human population reached 7.9 billion. Human beings are the only species that are close to exceeding the number of members of the brown rat and the house mouse.

Four-Toed Hedgehog | African Pygmy Hedgehog

The Four-Toed Hedgehog (Atelerix albiventris), also known as the African Pygmy Hedgehog, is a small mammal with a long snout, short spines on their back, and an underside that is covered in soft white or brown fur. It has an oval shaped body covered in spines that are used as protection by rolling into a ball when they feel threatened. As its name implies, it has 4 toes on each hindfoot.

Female Four-Toed Hedgehogs are typically larger than males and they also have large ears and whiskers. This species of hedgehogs is native to the central and eastern African region where they typically live in the savannah and cropland habitats. The Four-Toed Hedgehog is a nocturnal animal and is typically alone. Their diet includes insects, grubs, snails, spiders, and small plants. They are one of the most popular species of domesticated hedgehogs.

Four-Toed Hedgehogs have a shoulder height of 2.6”-4” (6.6-10.2 cm), body length between 6”-9” (15.2-22.9 cm), and an overall weight in the range of .9-1.3 lb (400-600 g). The tail of the Four-Toed Hedgehog is 1-1.5” (2.5-3.8 cm) in length. Four-Toed Hedgehogs have a typical lifespan of 2-4 years in the wild and up to 6-10 years when raised in captivity as a pet.

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.
