Did you know that hippo sweat is red? here because

Must read

Hippos (Hippopotamus amphibius) cannot wear white T-shirts. No, not because they don’t have a shirt (also!), but because their sweat would ruin any garment of that color. The reason is simple: the fluid they secrete from the skin is red like bloodbut not caused by any injury.

These creatures spend most of their time in the water, eating grass and aquatic plants. Their skin is 5 centimeters thick and mostly hairless.It is also very sensitive to both dryness and sunburn. Because they live in sub-Saharan Africa, they are definitely very difficult to protect from the sun’s rays.

The red matter is clearly neither blood nor sweat, as it is released from the subcutaneous glands (technically), but it can be considered as such because helps control pet’s body temperature. The fluid is initially colorless when secreted, then turns red within minutes and eventually turns brown as the pigment polymerizes.

This substance also adheres to the skin due to its high concentration of mucus (very difficult to create in the laboratory). In 2004, inquisitive and daring researchers collected the substance and examined it to understand what it was. Two pigments responsible for the color reaction were found: a red and an orange. Both absorb ultraviolet light and act as sunscreenthe red one also acts as an antibiotic by inhibiting the growth of pathogenic bacteria.

By the way, did you know that hippos spray feces when they see one of their own kind?
