Did you know that the first mammal was seen 178 million years ago? Yes! Mammals existed for a long time ago.
Any animal on earth is classified into six classes: invertebrates, vertebrates, fish, birds, amphibians, reptiles, or mammals.
So, is a horse a mammal?
Equine is a pure mammal due to its many characteristics. It has a backbone, middle ear bones, hair on its body and produces similar fertile offspring.
In this blog pots, let’s take a deep look into mammal’s characteristics and how horses fit into this taxonomic group. I’ll start the article without delaying any further.

What Is A Mammal?
How do you define a mammal? Any animal we see is one of the six amphibians, fish, vertebrates, mammals, etc.
What’s the best definition of a mammal?
Defining the mammals is not completed without discussing their four distinct features:
- Warm-blooded, hair/fur on the body
- Females with breast producing milk
- Giving birth to their species
They belong to kingdom Animalia and are chordates. Other little features that will be discussed in the later sections are:
- Sexual reproduction
- Triple circuit blood circulatory system
- The respiratory system with air warmed in nostrils.
Origin Of The Word Mammal
It is a common thing that mammals are names because of the possession of mammary glands. There must be a methodology behind this.
The word mammas originated from the Latin word, mamma meaning breasts. As mammals have essentially mammary glands to qualify for being mammals, they were named mammals.
That’s how we know the present term mammals.
What Makes An Animal A Mammal?
An animal does not become a mammal until it has some unique characteristics which make it different from other animals on this planet.
(Here’s a cool fact for you: Bats are the only warm-blooded animals that can fly).
What characteristics make an animal a mammal?
For an animal to be a mammal, it is compulsory to be warm-blooded , body hair, and females produce fertile offspring.
Warm-blooded animals bear cold easily as they have a layer of thick epidermis and hair on their body. The backbone in their body makes them among the class vertebrates.
The other distinct feature of female mammals is to produce milk from their mammary glands or breasts. It is vital for the healthy nourishment of their young ones.
A horse has all these unique characters and is considered to be a mammal.
Horses also possess the three ear bones, which we call:
- Anvil Hammer
Horses have these bones, which is important for any mammal.
10 Characteristics Of Mammals?
Mammals have complex structures and characteristics that no other organisms have. They are the most developed organisms among all the species and have the intellectual abilities to conquer anything with their intelligence.
Let’s have a look at the basic features of mammals:
The fertile offsprings produced by the mammals have to be fed in some way. Mammals have a unique way of feeding their babies.
The possession of mammary glands has enabled mammals to develop breasts. These mammary glands or breasts are then used after pregnancy to produce milk using the popular hormone oxytocin, and the milk is breastfed to young mammals.
Dual Hair On Coat And Guards
Mammals possess a double layer of coat which makes them resistant against all the weather and other damages.
Two types of hair are there, the coat and the guard hair. These hair have their prime importance, which cannot be neglected as they protect the mammas from the harm of light, heat, and cold.
Hair follicles are attached to the skin using nerve endings. The purpose of these follicles is to make sensations when a person touches the body of an organism.
Bones In Middle Ear And Jaws
Animals other than mammals don’t have middle ear bones in their body. Mammals possess these bones and are hence named malleus, incus, and stapes.
Mammals are the only animals with bones in the ear and jawbones. The skull of mammals has a single fusion of bones divided into the skull and the facial bones.
The middle ear bones are essential for transmitting sound waves to mammals’ outer and inner ears.
Mammals have essentially the best-modified structures, which makes them among the most complex and advanced organisms.
Mammals possess a diaphragm, and it’s a structure that is present in the chest cavity. The diaphragm helps in expelling and inhaling the air in the body. Since it is a muscular organ, any damage to the diaphragm may lead to shortness of breath and be fatal.
The diaphragm helps respiration efficiently play an important role in oxygenation by collaboration with the lungs.
Every mammal has a heart that has four chambers or cavities. Two of these chambers make the blood drain into the heart, and the other two drain the whole body’s blood.
A mammal’s heart is like a double pump. It pumps and gets the blood simultaneously. The four chambers are divided into two atria, and ventricles send and receive blood from the body after oxygenation.
At first, blood is received by the atria and sent to the lungs for oxygenation, after which ventricles receive the blood and send it to the central Aorta, which then pumps the oxygenated blood to all the parts of the body.
In this way, all body parts receive blood through the collaboration of these four heart chambers.
A mammal’s brain is essentially a vital structure that is not much developed in other animals.
Three brain parts are highly developed, like the cerebellum, which controls learning abilities and memory. Another part of the mammalian brain is the neocortex, handling perception of sensation, motor commands, and reasoning.
Mammals are organisms that possess warm-blooded metabolism. This characteristics feature is commonly seen in birds and theropod organisms.
Warm-blooded mammals have better physiological activities making the animals have better metabolism than any other Animalia kingdom species.
It is the same reason why animals can do extreme running like cheetahs and humans write books. In simple terms, warm-blooded animals are more active and do extensive exercise than cold-blooded ones.
Once Replacement of Teeth In Their Life
Unlike all animals, mammals have unique characteristics. The next on our list is the replacement of their teeth.
Mammals shed their teeth once in their life, and they grow the teeth back when they are stepping into teenage.
So, if we see horses, they also replace their teeth once in their life when they are less than one year old.
Young manes and geldings will also have their teeth replaced once in their life.
One of the distinct features of mammals is sexual reproduction, in which male and female mammals produce separate gametes.
Mammals use sexual reproduction to produce sperms and eggs, which fuse and form a zygote. Internal development of the new organism is seen, which may be delivered outside or inside depending on the mammals.
Horses also have a mechanism of sexual reproduction. It means the male and female horses mate, and the development of the baby horse takes place inside the female horse.
It is a beautiful mechanism that makes life continue on its way, ensuring the survival of species.
Closed Circulatory System
A closed circulatory system has three different parts:
- The pumping organ heart
- The blood vessels
- The fluid that flows in the vessels
All of these essential parts make a closed circulatory system.
The heart pumps the blood to the lungs and the body in the blood vessels divided into arteries, veins, and capillaries. The fluid that flows in these vessels is blood which makes 1/12th of the body weight.
It means if a horse weighs 500 kg, the blood volume is 40 liters on average.
THE BOTTOM LINE: All these characteristics are found in mammals and obviously in horses.
Is A Horse A Mammal Or Reptile?
A horse is a mammal. There is a basic difference between a mammal and a reptile.
Horses are not reptiles as mammals give the fertile offspring alive, while reptiles don’t give birth to the offspring and lay eggs.
Another thing that differentiates reptiles from mammals is that reptiles are cold-blooded animals.
How Are Horses Mammals?
Horses have reasonable characteristics, which make them mammals.
Horses are primarily mammals because they possess hair on their body, have warm blood, and breastfeed their young ones.
Horses Are Smart?
There’s no doubt that horses are smart. You may or may not agree with the fact that they are more intelligent than most animals.
Horses are brilliant and have inherited characteristics. Horses can also learn any skills like verbal and non-verbal clues. Their brain is developed enough to remember the most complex problems.
Thus, being mammals, their brain has the cerebellum, the center for learning and skill training ability.
Are Horses Herbivore Mammals?
So, Is a horse herbivore carnivore or omnivore?
A horse is naturally a herbivore, as the digestive system only enables the plants and herbs digestion. It is not normal for any horse to eat mat; the results may upset stomach with pathological infections as they lack enzymes to digest meat.
Why Are Horses Called Horses?
There’s a methodology for naming every animal. Like cats, dogs, and other animals, people think horses may be named because of some association with the behavior.
But horses were not named because of any methodology.
It is a mere theory that horses may be named because of the swift transportation to humans.
Scientific Name of The Horse
The scientific name for horse is Equuscaballus, which belongs to the phylum chordates, class Mammalia, and kingdom Animalia.
Are Horses Eyes The Largest of Land Mammals?
Many land mammals have large eyes, but horses also have big eyes than many animals.
But do horses have the largest eyes?
Horses don’t have the largest eyes, but maybe the second largest eyes. Their eye’s diameter is 1.34 meters. The only animal whose eyes are larger than horses is an ostrich with a diameter of 2 meters.
Frequently Asked Questions (FAQs)
A horse is a remote animal found worldwide and is classified into the mammalian class.
A horse possesses characteristics such as being a vertebrate, warm-blooded mechanism, fur and coat on its body, and mammary glands to feed the young offspring with a highly developed brain which marks the intelligence of a horse.
