Astonishing Giraffe Animal History & Facts: Evolution, Height, Survival Secrets

The giraffe (Giraffa camelopardalis) is the tallest terrestrial mammal on the planet and one of the most recognizable species of megafauna on the African continent. It is easily identifiable due to its great height, coat pattern, and elongated neck, and this ruminant mammal has been the topic of interest of scientists and wildlife lovers throughout centuries.

Whether you are studying the facts about giraffes, you are simply fascinated by how they evolve, or you are going to see giraffes in American zoos, this guide will take care of all the information in a clear and comprehensive way.

A giraffe is a very large African herbivorous animal of the Giraffidae family that includes okapi. Male adults may grow to a height of up to 19 feet, with the females being a bit shorter. Nevertheless, giraffes possess only seven spinal vertebrae in the neck, just like humans.

Some of the main features are:

Ossicones (horn-like structures of the head)

A prehensile tongue, 20 inches in length.

Distinct spotted patterns of coats.

Specialized digestion of ruminants.

Among the most controversial issues of evolutionary biology, one should mention the question of why giraffes have long necks.

There are two theories that are generally referred to by scientists:

Natural Selection (High Browsing Hypothesis)
During the droughts in the savanna biome, giraffes were able to access acacia leaves that were at high levels.

Sexual Selection Theory
Males also use the necking behavior, which is swinging their necks in fights to attract mates.

Giraffe fossils show signs of an ancient giraffe emerging millions of years ago in Africa. The genetic studies now contribute to the notion that the giraffe could be four species and not one, a significant scientific achievement in the current years.

The giraffes are found mainly in sub-Saharan Africa. They do well in open woodlands and grasslands, particularly in acacia tree-rich areas.

Familiar giraffe habitats include:

Serengeti

Masai Mara

Their historic range has been minimized by habitat fragmentation and agricultural development.

What do giraffes eat? It is mainly leaves, particularly acacia.

Their feeding habit is so specialized:

Their long, dark-colored tongue helps them in holding thorny branches.

Their mouths are cushioned with thick saliva against thorns.

Being ruminants, they cud to help them digest.

To feed its huge body, an adult giraffe is able to consume a substantial amount of foliage on a daily basis.

Giraffes are constructed to survive in the open savannahs.

Blood Pressure Adaptation
Giraffes are very tall; thus, the high blood pressure and specialized valves in their neck arteries ensure that they do not faint as they lower their heads.

Defense Mechanisms
The major predators are lions and, in some cases, the hyenas. The forward kick of a giraffe may be powerful enough to cause serious injury or kill a predator.

Speed
They have the capacity of running at speeds as high as 35 mph in short distances.

Giraffes reside in loose and fluid groups with no boundaries. Calves are born in approximately 15 months of gestation with the ability to stand in an hour.

Interestingly, giraffes use low-frequency humming sounds at night, something that has not been confirmed recently.

The giraffes are listed as a species at risk by the IUCN Red List.

Main threats include:

Habitat loss

Poaching

Human-wildlife conflict

Fragmented ecosystems

Such organizations as the Giraffe Conservation Foundation are designed to preserve the population and ensure the preservation of biodiversity. Under CITES agreements, international trade is controlled.

The nearest living relative of the giraffe is the okapi, or rather known as the forest giraffe. Okapis are not like giraffes and inhabit thick forests and also have shorter necks.

The two are evolutionarily similar, but they adapted to ecological niches.

When you are looking to see giraffes in the American zoos, there are a few accredited zoos with great views and education programs to see.

Popular locations include:

San Diego Zoo

Bronx Zoo

Smithsonian National Zoo

Dallas Zoo

In other zoos, there are giraffe feeding experiences. The prices differ depending on the place and the type of ticket and are usually provided between the general entry extras and the booked animal encounters. When visiting zoos, always make sure that they are AZA-accredited so that the wildlife is treated in an ethical manner.

Giraffes take naps of not more than 20 to 30 minutes a day.

The pattern of the coats of each giraffe is different.

They do not often sleep flat out because of the dangers of predators.

The thorny branches are kept off by their long eyelashes.

Giraffes have been fashioned by nature, sexual, and environmental selection pressures as evolutionary marvels. Being some of the ecological determinants in African savannas, they are critical in ensuring the balance of vegetation.

Regardless of whether you are a wildlife biology student, a teacher, or planning a visit to a zoo in the United States, knowing the history and facts of giraffes, you will soon realize how incredible this species can be.
