The Giraffe: Characteristics, Taxonomy, and Evolution

• The giraffe is a large African mammal, with extremely long neck and legs, horn-like ossicones, and spotted coat patterns.

• It is the tallest terrestrial animal and largest ruminant on Earth.

• Giraffes were thought to be one species with nine subspecies, but recent research has proposed dividing them into up to eight extant species due to new DNA and morphological measurements.

• The giraffe's scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east.

• Giraffes usually inhabit savannahs and woodlands, and their food source is leaves, fruits, and flowers of woody plants, primarily acacia species.

• Lions, leopards, spotted hyenas, and African wild dogs may prey upon giraffes.

• Giraffes live in herds of related females and their offspring or bachelor herds of unrelated adult males, and males establish social hierarchies through "necking", combat bouts where the neck is used as a weapon.

• Giraffes are classified under the family Giraffidae, along with their closest extant relative, the okapi.

• The elongation of the giraffe's neck appears to have started early in the giraffe lineage, and comparisons between giraffes and their ancient relatives suggest vertebrae close to the skull lengthened earlier, followed by lengthening of vertebrae further down.

• The giraffe genome is around 2.9 billion base pairs in length, and a small group of regulatory genes in the giraffe appear to be responsible for the animal's height and associated circulatory adaptations.

• The International Union for Conservation of Nature (IUCN) currently recognizes only one species of giraffe with nine subspecies, but recent studies suggest the existence of multiple species and subspecies.

• Fully grown giraffes stand 4.3–5.7 m tall, with males taller than females, and their coat pattern has been claimed to serve as camouflage in the light and shade patterns of savannah woodlands.

• The giraffe has an extremely elongated neck, which can be up to 2.4 m in length, and each cervical vertebra is over 28 cm long, comprising 52–54% of the length of the giraffe's vertebral column.The Anatomy, Behavior, and Ecology of Giraffes

• Giraffes have long necks and legs, with the neck consisting of only seven vertebrae but reaching lengths up to 2 meters.

• The elongation of their necks is thought to have evolved through competitive pressure to reach higher food sources and may also aid in sexual selection.

• Giraffes have a unique gait of walking and galloping, with their front legs functioning as knees and a suspensory ligament supporting their weight.

• They have a small lung volume relative to their mass, but their long necks provide a large amount of dead space for evaporative heat loss to cool their brains.

• Giraffes are ruminants with a four-chambered stomach, adapted to their specialized diet of browsing on tree twigs, shrubs, grass, and fruit.

• They have a fission-fusion society, with long-lasting social groups based on kinship, sex, or other factors, and males are responsible for dispersal.

• Giraffes communicate through a variety of sounds and body language, with males competing for mating opportunities with oestrous females.

• Female giraffes give birth standing up, and the calf is born head and front legs first, able to run within a few hours.

• Giraffes inhabit savannahs and open woodlands, preferring areas dominated by Acacieae, Commiphora, Combretum, and Terminalia trees.

• They have a significant impact on their habitat, delaying the growth of young trees and giving "waistlines" to tall trees.

• Giraffes require less food than other herbivores due to the concentrated nutrients in their diet and their efficient digestive system.

• While giraffes can reach sprint speeds of up to 60 km/h, they are not competent swimmers due to the cumbersome nature of their long legs in water.Fascinating Facts about Giraffes

• Giraffes have a unique coat pattern that provides them with camouflage.

• The ossicones on their head raise up in a few days after birth.

• Mothers with calves gather in nursery herds and sometimes leave their calves in a "calving pool".

• Calves ruminate at four to six months and stop nursing at six to eight months.

• Male giraffes use their necks as weapons in combat, a behavior known as "necking".

• Necking is used to establish dominance and males that win necking bouts have greater reproductive success.

• Giraffes have high adult survival probability and can live up to 38 years.

• Lions are their only major predator, but calves are more vulnerable and are preyed on by other animals.

• Giraffes have cultural significance and have been depicted in art and literature throughout history.

• Giraffes have been kept in captivity since ancient times, and are popular attractions in modern zoos.

• Giraffes have been hunted for their meat and various body parts, leading to a decline in their population.

• Giraffes are currently classified as Vulnerable by the IUCN due to habitat loss and direct killing for bushmeat markets, with some subspecies being critically endangered or near threatened.
