Many of us assume that animals don’t sweat as we do, but the truth is that many animals sweat.
Some species have evolved unique methods for cooling their bodies down in hot and humid climates.
From Dogs to Hippopotamus, a surprising number of animals sweat! In this post, we’ll look at unexpected animals that produce sweat and discuss why and how they can do it.
1. Hippopotamus
The hippopotamus is first on our list of animals that sweat. Contrary to popular belief, the hippopotamus does not create any sweat, but it is remarkable for another reason.
This large African herbivore secretes a crimson, sticky, mucus-filled substance that combines an antibiotic, sunblock, and moisturizer.
This sweat is originally colorless, but it turns red and brown when interacting with other colors.
Even though it doesn’t contain blood or true perspiration, it has the term “blood sweat” from people. They are highly sensitive and prone to drying out the hippopotamus’s skin.
They enjoy staying in the water or playing in the mud because they keep their sensitive skin hydrated.
Nonetheless, they are very protective of their territory and occasionally travel on land to drive away predators or other invaders.
Until they can go back into the water, their mucus provides additional defense and lubrication for their skin.
2. Dogs
You might be a little shocked to learn that dogs are also one of the animals that sweat. Its paw pads include a ring of eccrine glands known as merocrine glands.
These serve the same purpose of cooling the body as human sweat glands.
On hot days, if you look closely, you can notice sweat accumulating around the paws. Sweat is made possible by the skin’s relative bareness.
This is also why only the paw pads perspire. Due to their dense fur, dogs cannot sweat throughout most of their bodies. To be cool, they must still be panting.
3. Zebra
Considering their thick, fur-coated bodies, one might not expect zebras to sweat. However, this iconic creature is one of the animals that sweat.
Zebras have sweat glands that help them regulate their body temperature. When the weather gets hot, zebras will produce sweat on their bodies, particularly in areas with less fur, such as their underbelly.
This process helps to cool them down and prevent overheating. Interestingly, zebras’ sweat also acts as a sunscreen, protecting against the harsh African sun.
So, next time you see a zebra shimmering in the heat, remember that even they need a little help staying cool!
4. Chimpanzees
Next on our list of animals that sweat is the Chimpanzee. To assist them in controlling their body temperature, chimpanzees have a high ratio of eccrine to apocrine glands.
However, due to the reduced density of sweat glands on their skin and thick fur, their sweating could be more effective than a person’s.
Because of this, the chimpanzee nevertheless uses various strategies to stay cool.
5. Donkey & Horse
Anyone who has spent enough time working with horses will know that they sweat a lot while exerting themselves.
When exercising or working in heated surroundings, they can also develop a kind of foam or lather all over their bodies, especially around the neck and hind legs.
When sweat is in a region where there is friction between the thighs, it appears foamy because this foam contains a special protein called latherin.
The latherin allows the sweat to work through the entire surface of the waterproof hair, from the base to the tip.
This, in turn, increases its exposure to air, so it will eventually evaporate from the body.
6. Old World monkeys
A family of primates known as the “Old World monkey” is primarily indigenous to Africa and Asia.
The most well-known members of this group are baboons and macaques.
It excludes the lemurs of Madagascar and other New World monkeys like marmosets and tamarins.
About 25 species of Old World monkeys are in the macaque genus, most indigenous to Asia.
The Rhesus macaque and the Japanese macaque are likely the two most well-known species.
Although they are one of the animals that sweat, it’s not as noticeable as in their great ape cousins.
This is possible because their skin has approximately equal eccrine and apocrine glands.
7. Gorilla
Gorillas, a relative of humans, can sweat in hot temperatures to stay cool and comfortable, but the sweat glands serve more than just thermoregulation.
The axilla or axillary organ is specialized tissue found in the armpits of gorillas, chimpanzees, and humans.
This organ is very prominent in male gorillas. It has four to six layers of glands that release sweat and other odors.
The main benefit is that it facilitates group communication. When prospective dangers are lurking nearby, the scent sends an alert signal to the other group members.
It serves as a helpful indicator of reproductive readiness.
8. Elephants
Elephants are one of the largest land mammals and, like most mammals, can sweat.
However, their sweat glands are not distributed evenly across their body.
Instead, they have a few sweat glands on their forehead, and most heat dissipation occurs through their large ears.
Elephants flap their ears to create air currents that evaporate the sweat, cooling their body temperature.
This is especially important in their hot and dry environments.
Without sweat production and heat dissipation, elephants could easily overheat and suffer from heatstroke.
9. Camel
Camels are the next animal on our list of animals that sweat. They are renowned for their ability to withstand harsh desert conditions and sweating plays a crucial role in their survival.
Unlike other mammals, camels have specialized sweat glands in their fur that allow them to regulate their body temperature.
When the temperature rises, these glands produce sweat that evaporates, cooling the camel’s body.
This adaptation enables camels to endure high temperatures and long periods without water, making them well-suited to their arid habitats.
Their ability to sweat is one of the many remarkable adaptations that have helped camels thrive in extreme environments.
10. Human
This is the last animal on our list that sweats. Although other species also perspire, Kamberov points out that human sweat is unique.
Humans have sweat glands, which release water onto the skin’s surface.
Although horses have a different sort of gland typical of running animals, they nevertheless perspire.
These are known as apocrine glands, and they are linked to the body hair of horses.
What they secrete, according to Kamberov, “is not water, but rather a mixture of water, lipids, fats, and proteins.” “The chemical being released is different; it’s a different kind of sweat.
