Believe it or not, the question “What Color Is A Hippopotamus?” is more complicated than it seems! While we often picture hippos as gray, their skin color isn’t quite that straightforward. Let’s delve into the fascinating world of hippo pigmentation and uncover the truth behind their surprisingly colorful complexion.
The Myth of the Gray Hippo
While many describe hippos as gray, their skin is actually closer to a brownish-gray or purplish-gray hue. This misconception likely stems from the fact that hippos spend a significant amount of time submerged in water, which can make their skin appear darker and less vibrant.

A Spectrum of Shades: Factors Affecting Hippo Skin Color
Several factors contribute to the subtle variations in hippopotamus skin tones:
- Species: There are two distinct species of hippopotamus – the common hippopotamus and the pygmy hippopotamus. Common hippos tend to have a darker, more grayish coloration, while pygmy hippos exhibit a brownish-black hue.
- Environment: Hippos inhabiting muddy rivers and lakes often appear darker due to the sediment coating their skin. Conversely, those residing in clearer waters may showcase lighter, more vibrant skin tones.
- Sun Exposure: Like humans, hippos can experience changes in pigmentation with prolonged sun exposure. Their skin may develop a reddish or orange tinge, particularly on the upper parts of their bodies.

Beyond Gray: The Science of Hippo Skin Secretions
Here’s where the “color” of a hippopotamus gets even more intriguing. Hippos secrete a special substance called “hipposudoric acid” through their skin. This oily, reddish-orange secretion acts as a natural sunscreen, moisturizer, and antibacterial agent, protecting their sensitive skin from the harsh African sun and potentially harmful bacteria.
“Hippopotamus sweat isn’t actually sweat in the traditional sense,” explains Dr. Sarah Williams, a wildlife biologist specializing in African megafauna. “It’s a unique secretion that plays a crucial role in their overall health and well-being.”
While hipposudoric acid itself isn’t the sole determinant of their skin color, it contributes to the reddish-orange hues sometimes observed, particularly when the secretion is fresh and concentrated.

So, What Color IS a Hippopotamus?
The answer, like the hippo itself, is complex and multifaceted! Their skin color is a fascinating interplay of natural pigmentation, environmental factors, and specialized secretions. While not definitively gray, brown, or orange, hippos showcase a unique and ever-changing spectrum of colors that highlight their incredible adaptations to the African wilderness.
FAQs about Hippopotamus Skin Color
Q: Is the reddish-orange secretion from hippos blood?
A: No, the red-orange substance is hipposudoric acid, a specialized secretion that acts as a natural sunscreen, moisturizer, and antibacterial agent.
Q: Can hippos change color like chameleons?
A: While hippos don’t possess the same color-changing abilities as chameleons, their skin tone can appear to shift due to water, sun exposure, and the presence of hipposudoric acid.
Q: Do all hippos secrete the reddish-orange substance?
A: Yes, both common hippos and pygmy hippos secrete hipposudoric acid, although the amount and concentration may vary.
