Until now, the giraffe has been classified as a single species, with nine subspecies. However, the IUCN has now evaluated extensive genetic data - confirming that there are actually four distinct species

It is undoubtedly one of the most majestic creatures in the animal kingdom. 

But it turns out there’s not just one species of giraffe. 

In fact, there are four. 

Scientists from the International Union for Conservation of Nature (IUCN) have confirmed that the Northern Giraffe, Reticulated Giraffe, Masai Giraffe, and Southern Giraffe are distinct from one another. 

Despite looking eerily similar, these species are actually as different as brown and polar bears! 

Michael Brown, a researchers in Windhoek, Namibia, who led the assessment, explained: ‘Each species has different population sizes, threats and conservation needs. When you lump giraffes all together, it muddies the narrative.

‘Recognising these four species is vital not only for accurate IUCN Red List assessments, targeted conservation action and coordinated management across national borders. 

‘The more precisely we understand giraffe taxonomy, the better equipped we are to assess their status and implement effective conservation strategies.’

Until now, the giraffe has been classified as a single species, with nine subspecies. 

However, the IUCN has now evaluated extensive genetic data – confirming that there are actually four distinct species. 

These species can be found across the African continent. 

The Northern Giraffe (Giraffa camelopardalis) is found in Chad, Central African Republic, Cameroon, Democratic Republic of Congo, and South Sudan, and is known for its long and thin ossicones – the bony structures found on giraffes’ heads. 

The Reticulated Giraffe (Giraffa reticulata) lives in Kenya, Somalia, and Ethiopia, and is the largest of the four species – reaching impressive heights of up to six metres. 

The Masai Giraffe (Giraffa tippelskirchi) is native to East Africa, with sightings in Kenya, Tanzania, and Zambia. 

This species is known for the distinctive, leaf–like patterning on its fur. 

Finally, as the name suggests, the Southern Giraffe (Giraffa giraffa) lives in Angola, Namibia, Zimbabwe, South Africa, and Zambia. 

The Reticulated Giraffe (Giraffa reticulata) lives in Kenya, Somalia, and Ethiopia, and is the largest of the four species - reaching impressive heights of up to six metres

This species is the most populous of the four. 

Experts believe the four giraffe lineages began to evolve separately of each other between 230,000 and 370,000 years ago. 

In the wild, the four different species do not mate, although conservationists have found it is possible to get the different species to mate under certain circumstances.

Sadly, the populations have declined sharply in the past century to around 117,000 wild giraffes throughout the African continent. 

With four distinct species, it makes the situation worse, as each individual species is under even greater threat from rapidly declining numbers and a lack of intermixing. 

‘We estimate that there are less than 6,000 northern giraffes remaining in the wild,’ Dr Julian Fennessy, director of the Giraffe Conservation Foundation, previously explained. 

She added that ‘as a species, they are one of the most threatened large mammals in the world.’

ZEBRA STRIPES: A RANGE OF THEORIES HAVE TRIED TO ANSWER WHY THEY EXIST

There are several possible explanations as to why zebras have black and white stripes, but a definitive answer remains to be found. 

There are a number of theories which include small variations on the same central idea, and have been divided into the main categories below.

  1. Apparent size increase 
  2. Visibility in poor light 
  3. Moving stripes may dazzle predators
  4. Camouflage 
  5. Social benefits
  6. Fitness indication 
  7. Protection from tsetse flies. 

The areas of research involving camouflage and social benefits have many nuanced theories.

For example, social benefits covers many slight variations, including:

  • Zebras recognise each other on the basis of their stripes
  • This is especially important in the visual communication between mothers and their foals
  • Stripes might also be visual markers for group bonding or to direct companions to particular parts of the body for grooming.

Anti-predation is also a wide-ranging area, including camouflage and various aspects of visual confusion.   

These explanations have been thoroughly discussed and criticised by scientists, but they concluded that the majority of these hypotheses are experimentally unconfirmed.

As a result, the exact cause of stripes in zebra remain unknown.
