Ceratotherium simum simum

Irish Name: Srónbheannach bán deisceartach

Southern white rhinos can weigh up to 2.3 tonnes and have a wide flat mouth, thick grey skin and two horns- one large horn to the front and a smaller horn further up their head.

Fun Facts

Not-so-white rhino

There is actually no colour difference between the black and white rhinos species. The 'white' component of the name may have resulted from a mistranslation of the Afrikaans word “wyd” meaning “wide'

Highly endangered species

There are only two remaining individuals of other subspecies of white rhino, the northern white rhino. This is in comparison with the estimated 17,000 individuals of the southern white rhino species. The two remaining northern white rhinos are called Fatu and Najin and both are female and living in a conservancy in Kenya. The last male rhino, Sudan, died in 2018.

Scientists are attempting to use frozen sperm from deceased males to impregnate the two females to try and save the species.

Long horn

Southern white rhinoceros' front horns are on average about 60 cm long but have been known to grow up to lengths of 1.5 metres. Their horns are composed of keratin and are used as weapons against predators, to display dominance when threatened by other rhinos.

The southern white rhino has been classified as Near Threatened by the International Union for Conservation in Nature.

Current population estimate

Around 18,000 individuals

Threats

Poaching is the biggest threat to southern white rhinos.

All rhino species are hunted for their horns- in fact, poaching is the main cause of death for rhinos. Tragically their horns are mostly just used as trophies for the hunters as a status of wealth. They have also been used in Chinese medicine for the last 2,000 years to treat fever, gout and many other illnesses however there is no medical backing to this theory.

Like a lot of other species, they are also victims of habitat loss and political conflict in their native Africa.

What is Dublin Zoo doing?

Dublin Zoo supports the Lowveld Rhino Trust in Zimbabwe, which is involved with treating wounded and orphaned rhinos, catching poachers, monitoring rhino populations and community outreach programmes

We are also part of the European breeding programme for this species.
