How do spots help giraffes survive?
Giraffe’s patches (spots) are first and foremost for camouflage. A giraffe can send blood through these small branches into the middle of the patch in order to release heat through this system. Each patch acts as a thermal window to release body heat.
How do giraffes maintain a stable internal environment?
Giraffes have very large bodies and their blood circulation has to be maintained. They have large hearts and high blood pressure to maintain homeostasis. Their tight skin aids in blood circulation by increasing the pressure.
Why do giraffes have patterns?
Giraffes — like tigers, zebras and jaguars — are covered in patterns that aid in regulating body temperature and help signal to other animals that they’re part of the same species. The markings also act as camouflage, optically breaking up the body shapes of animals to hide them from predators.
Are giraffe spots like fingerprints?
A giraffe’s spot pattern is similar to one of our fingerprints. It’s a unique identifier for each animal, helping other giraffes recognize who is in their family groups.
How do giraffes protect themselves from extreme weather conditions?
They have the ability to completely close their nostrils to keep sand and dust out during African dust storms. Their long tongues are not only long enough to reach the leaves they need but are also very tough, allowing them to eat thorns as well. They use their tongues to remove parasites from their faces, too.
How does a giraffe stay warm?
Barns with heated floors are optimal, as the heat will rise and warm the animal’s legs and body. By way of example, one giraffe became hypothermic and died inside a heated, albeit drafty, barn where the upper level of the barn was nearly 70 degrees but the lower area was only 45 degrees.
What animals have Ossicones?
Ossicones are columnar or conical skin-covered bone structures on the heads of giraffes, male okapi, and some of their extinct relatives.
How do a giraffes spots keep them cool?
Giraffes live in exceptionally dry, hot conditions, but they don’t sweat. So how do they keep cool? The answer lies in their beautifully patterned skin, which acts like a network of thermal windows. Giraffes can direct their warmer blood to the vessels at the edges of the spots, forcing heat out of their bodies.
Do giraffes get their spots from their mothers?
Giraffes get their characteristic patterns of spots from mom — but not from their dads, a new study finds. The mottled patterns that adorn Africa’s tallest creatures are passed down from their mothers, a new study suggests. A giraffe inherits spots that are similar to those of its mother in two ways.
Why do giraffes have patches on their skin?
A giraffe can send blood through these small branches into the middle of the patch in order to release heat through this system. Each patch acts as a thermal window to release body heat. The left image below shows the patches of a giraffe and the one on the right shows the intensity of heat radiation.
How do giraffes stay so cool?

What are the characteristics of a giraffe?
Giraffes are the tallest mammals on Earth. Their legs alone are taller than many humans—about 6 feet. They are social animals that live in herds with dozens of members, although most of these groups include mothers, their offspring, and several young individuals. Some mature adult giraffes prefer to stay alone.
