I get a lot of questions sent to me about different animals, and while we are told that elephants are mammals, the lack of fur confuses some people.
Elephants are mammals as they are warm-blooded, have small amounts of hair, possess mammary glands, have a four-chambered heart, and have mammalian teeth.
To find out why these gentle giants are classified as mammals, let us dive deeper into the anatomy and behavior of elephants to see what sets them apart from other animals.

What Is A Mammal?
- Mammals are warm-blooded animals, meaning they can maintain a consistent body temperature regardless of the external environment.
- Mammals have hair or fur on their bodies.
- Mammals possess mammary glands, which are used to produce milk for their young.
- Mammals have three middle ear bones (malleus, incus, and stapes) that help them to hear well.
- Mammals have a four-chambered heart, which separates oxygenated and deoxygenated blood.
- Mammals have a neocortex, a region of the brain responsible for higher cognitive functions such as learning, memory, and decision-making.
- Mammals are characterized by their unique jaw and tooth structure, specialized for different diets such as herbivorous, carnivorous, and omnivorous.
The physical characteristics of mammals are a diverse and fascinating set of biological traits. It is important to understand these features to accurately classify an animal as a mammal, including the elephant.
First, mammals have body hair or fur, which helps them regulate their temperature by trapping heat and keeping their bodies warm. Additionally, they all possess mammary glands that produce milk to nourish their young until they can effectively find food.
This sets them apart from other animals who feed their offspring with regurgitated materials instead. Furthermore, most mammals have diaphragm muscles inside their chest cavity, which enable them to take deep breaths for increased oxygen intake; this feature gives mammals greater stamina than many other creatures.
Mammalian teeth come in various shapes and sizes depending on what kind of diet they consume. For example, carnivorous animals such as tigers usually have sharp incisors at the front used for tearing meat. In contrast, herbivores like cows typically have flat molars at the back used for grinding vegetation.
Another interesting fact is that almost all of them only grow two sets of teeth during life: one when born (known as deciduous) and another later when reaching maturity (called permanent).
Finally, mammals also exhibit distinct reproductive patterns compared to other animals since almost all give birth to live young rather than laying eggs outside the mother’s body like many birds do or using external fertilization like some fish species use.
Females often nurse their newborns with milk produced from mammary glands in the upper torso region until they can fend off predators and locate food sources independently.

What Is An Elephant?
Elephants are the largest land animals in the world and can be found in Africa and Asia. They have distinctive trunks and tusks for gathering food, carrying items, and making sounds. Most elephants form herds of related females with their young.
Elephants also have some unique traits that set them apart from other mammals. For example, their skin has two layers – an outer layer of tough leathery tissue and another inner layer rich in fat cells, which helps insulate them against heat and cold temperatures.
Their long lifespans (up to 70 years) make them one of the longest-lived mammal species. Additionally, elephants exhibit complex behavior, such as mourning rituals when a family member dies or showing joy when reunited after being separated for extended periods.
One of the first things people notice about elephants is their long trunks. This appendage is a combination of two noses fused; it’s so dexterous that an elephant can use its trunk like a hand to pick up objects or spray dust on itself for protection against insects. Elephants also have large ears, which help regulate body temperature by flapping them around.
Finally, elephants have very thick skin with little hair, except those living in cooler climates with more fur than others. The thickness helps protect them from thorns and abrasions while they roam through dense vegetation; it also keeps them cool when temperatures rise during the summer months.
Their tusks are composed of ivory, formed from layers upon layers of dentine; these serve many purposes, such as digging for roots, gathering food, fighting off predators, and defending themselves in battles between males over territory or mating rights.

As we have seen, elephants are unique animals with distinct physical characteristics. But what is the scientific definition of a mammal?
A mammal is a warm-blooded vertebrate animal of a class that is distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young.
Mammals are vertebrates that nurse their young using milk produced by mammary glands. This means any animal, from cats to whales, can be classified as a mammal. It also applies to elephants, who meet all the criteria for being called a mammal.
When looking further into the details of classification, scientists use phylogenetic trees, which organize living organisms according to common ancestry and evolutionary relationships. Regarding elephants specifically, they belong in the clade Afrotheria along with several other species like manatees and tenrecs.
All these animals share similar traits, such as having different types of specialized teeth or sharing certain anatomical features like an elongated snout or trunk, making them stand out compared to other forms of life on Earth.
To sum up our discussion about classifying mammals, no doubt based on both general definitions and more detailed phylogenetic trees, elephants do indeed fall under the designation of mammals. They possess many unique features but maintain enough similarities with other creatures to be considered part of this group.
