Overview

Giraffes (genus Giraffa) are the tallest living land animals, native to sub-Saharan Africa. Their disproportionately long necks and legs, distinctive coat patterns, ossicones (horn-like skull protuberances), and specialised cardiovascular system are the most visually striking features of any large African mammal. Recent genetic studies have proposed splitting what was traditionally treated as a single species into multiple species; classifications differ between sources.

Habitat & Range

Giraffes are found in savanna, open woodland, and grassland with scattered trees across a range of African regions. They are non-migratory in the strict sense but use seasonal patterns of movement to track food and water availability. Populations are increasingly fragmented across their range due to land-use change.

Diet

Giraffes are browsers, feeding largely on the leaves and shoots of trees and shrubs — particularly Acacia species. Their long necks, prehensile tongues and tough lip and palate tissues allow them to feed on thorny vegetation that many other herbivores cannot easily access. A wild giraffe spends a large part of each day feeding.

Behavior

Giraffes form loose social groups whose composition shifts over time ("fission-fusion" dynamics). Calves are sometimes left in nursery groups while adults feed at distance. Male giraffes engage in a behaviour called "necking", in which they swing their long necks against one another to establish dominance during the breeding season.

Human Interaction & Conservation

Conservation pressures include habitat loss and fragmentation, civil conflict in parts of the range, illegal hunting for meat and skins, and the displacement of populations by infrastructure and agriculture. Several giraffe populations and recognised subspecies (or species, depending on classification) face significant risk. Up-to-date status by population is best taken from the IUCN Red List and current conservation organisations.

Similar Animals

The okapi (Okapia johnstoni) is the giraffe's closest living relative — a forest-dwelling species of Central Africa with a much shorter neck and a strikingly different coat pattern. No other living animal closely resembles a giraffe in body plan.

Frequently Asked Questions — Giraffe

Why do giraffes have such long necks?

The leading evolutionary hypotheses concern feeding (access to vegetation other browsers cannot reach) and intraspecific competition between males. Both pressures probably contributed. Despite their length, giraffe necks contain the same seven vertebrae found in other mammals — the individual bones are simply much longer.

How tall is a giraffe?

Giraffes are the tallest living land animals. Heights vary by individual and population; precise figures should be taken from specific studies. Newborn calves are already large at birth, reflecting the long gestation typical of giraffe-sized mammals.

How do giraffes drink water?

Because their forelegs are long and their necks, while long, do not reach the ground from a standing position, giraffes have to splay their forelegs and lower their head awkwardly to reach water — a posture in which they are momentarily vulnerable to ambush predators.

Are there multiple giraffe species?

Traditionally, all giraffes were treated as a single species (Giraffa camelopardalis) with several subspecies. Recent genetic studies have proposed splitting them into multiple species. Classification is an active area of work and differs between sources.
