No, White rhinos are not extinct, but their situation is complex. The southern white rhino has seen a remarkable recovery, with thousands thriving in protected areas. However, the northern white rhino is in a dire state, with only two females remaining, making natural reproduction impossible.
This means the northern subspecies is functionally extinct, though scientists are working hard to save it. Let’s break down the details to understand their status, populations, and the challenges they face.
Subspecies of White Rhinos
White rhinoceroses (Ceratotherium simum) are divided into two subspecies: the southern white rhinoceros (C. s. simum) and the northern white rhinoceros (C. s. cottoni).
The southern white rhino, with over 18,000, is doing better, mostly found in South Africa, Namibia, Zimbabwe, and Kenya. The northern white rhino, sadly, has only two females left, Najin and Fatu, both in Kenya’s Ol Pejeta Conservancy, and they can’t reproduce naturally since the last male died in 2018.
Though they share a common ancestry, these subspecies differ markedly in their current conservation status, geographic distribution, and population dynamics.
Table: Difference between Southern White and Northern White Rhinos
| Aspect | Southern White Rhino | Northern White Rhino |
|---|---|---|
| Taxonomy and Range | Historically, northern white rhinos ranged across portions of East and Central Africa – northwestern Uganda, southern Chad, southwestern Sudan, the eastern Central African Republic (CAR), and northeastern Democratic Republic of the Congo (DRC). Now, only two females are left. | Historically, northern white rhinos ranged across portions of East and Central Africa – northwestern Uganda, southern Chad, southwestern Sudan, the eastern Central African Republic (CAR), and northeastern Democratic Republic of the Congo (DRC). Now, only two females are left. |
| Physical Characteristics | Adults can reach up to 1.85 m at the shoulder and weigh up to 2700 kg (males), with females marginally smaller at around 1700 kg. The square-lipped muzzle is adapted for grazing on short grasses in savanna and grassland habitats | Similar in appearance to the southern white rhino but genetically distinct, slightly smaller, weigh between 1400-1600 kg and are adapted to savanna woodlands. |
| Population | There are over 18,000 southern white rhinos in the wild, the majority located in South Africa alone. Rest of the populations inhabit Namibia, Botswana, Zimbabwe, Eswatini, Uganda, Zambia, and even Kenya | Only two northern white rhinos remain, both female (Najin, born 1989; and Fatu, born 2000). With no living males left, they are incapable of natural reproduction, rendering the subspecies functionally extinct in the wild. |
| Conservation Status (IUCN) | Near Threatened | Critically Endangered, Functionally Extinct. |
Is the Northern White Rhino Extinct?
No, northern white rhinos are not yet officially extinct, but they are functionally extinct. As of June 2025, only two northern white rhinos remain: Najin and Fatu, both females are protected 24/7 at the Ol Pejeta Conservancy in Kenya. The last male, Sudan, died in 2018, marking the end of natural reproduction.
Why Northern White Rhino Functionally Extinct?
Without males, natural breeding is impossible. Both females are beyond their reproductive prime, with Najin’s health issues further complicating matters.
Efforts to Prevent Total Rhino Extinction
Scientists are using advanced reproductive technologies, including in vitro fertilization (IVF), to create northern white rhino embryos.
Eggs from Najin and Fatu are fertilized with sperm from deceased males (including Sudan), and these embryos are stored for future implantation into southern white rhino surrogates.
A significant breakthrough in January 2024 saw a southern white rhino surrogate, Curra, become pregnant with a southern white rhino embryo via IVF, though she died before giving birth.
This success demonstrates the potential for similar efforts with northern white rhinos, offering hope but with uncertainty, given the complexity.
Conservation Efforts for Northern White Rhinos
Scientists and conservationists are employing several cutting-edge strategies to prevent the complete loss of the northern white rhino’s unique genetic lineage:
Cryopreservation of Gametes and Oocytes
During Najin and Fatu’s lifetimes, researchers collected and cryogenically preserved sperm (from deceased males) and oocytes (egg cells) from the two remaining females. This genetic material is stored in specialized biobanks to facilitate future in vitro fertilization (IVF) efforts.
In Vitro Fertilization (IVF) and Embryo Transfer
San Diego Zoo Institute for Conservation Research has successfully matured oocytes from Najin and Fatu into viable embryos by fertilizing them with frozen sperm from deceased males such as Sudan.
These embryos are then transferred into surrogate southern white rhino females (C. s. simum), aiming to carry northern white rhino offspring to term.
Stem Cell and Induced Pluripotent Stem Cell (iPSC) Research
Some laboratories are exploring the generation of gametes (both sperm and eggs) from induced pluripotent stem cells derived from existing northern white rhino cells.
If successful, this approach could create new sperm or eggs, bypassing the limitation of there being no living males. However, this remains in experimental phases and faces complex biological and ethical considerations.
Genome Editing and Cloning Prospects
There is ongoing debate around the possibility of using advanced cloning techniques, such as somatic cell nuclear transfer, to produce northern white rhino clones if high-quality cell nuclei can be retrieved.
Genome editing technologies might correct genetic defects or amplify genetic diversity by editing the genomes of existing cells. These methods carry significant scientific hurdles and ethical discussions, but offer a potential path forward.
Each of these strategies depends on collaborative networks of zoos, research institutions, and conservation NGOs. Progress is incremental and subject to the challenges of low gamete numbers, potential genetic bottlenecks, and the long gestation time of rhinos (approximately 16 months).
Threats to White Rhinos
Poaching for Horn
Drivers of Demand: Rhino horn commands exorbitant prices on the black market up to $60,000 per kilogram.
Although no scientific evidence supports traditional medicine claims, demand persists in parts of Asia for alleged medicinal properties, status symbols, or ornamental carvings.
Organized Crime: Poaching syndicates now use sophisticated technology, night-vision equipment, silencers, and even helicopters to locate and kill rhinos.
This threat is acute for both subspecies but proved far more catastrophic for northern whites due to their already dwindling numbers.
Habitat Loss and Fragmentation
Agricultural Expansion & Land-Use Change: As human populations grow, land conversion for farming or settlement shrinks rhino habitats. Fragmented landscapes reduce viable grazing areas and impede natural movement corridors, increasing human–wildlife conflict and reducing genetic exchange among populations.
Political Instability: In former range countries like DRC and CAR, armed conflicts and weak governance have hindered on-the-ground conservation, allowing poachers to operate with impunity and further eroding habitat protections.
Climate Change
Changing rainfall patterns can affect grassland productivity, leading to reduced food availability. White rhinos, as large grazers, rely on a steady supply of short grasses; shifts in ecosystem composition may force them to range more widely or suffer from nutritional stress.
What We Can Do
- Support Anti-Poaching Initiatives:
Donating to or volunteering with organizations that fund ranger patrols, install surveillance (e.g., drones, camera traps), and provide training can directly reduce poaching incidents. Many NGOs allow donors to ‘adopt’ a rhino, funding specific individuals’ protection. - Promote Sustainable Tourism:
Visiting rhino sanctuaries and national parks under regulated ecotourism programs generates vital income for conservation and local communities. When local populations benefit economically from rhino preservation, they have stronger incentives to protect rather than poach. - Raise Public Awareness:
Education campaigns through social media, school programs, and community outreach to help dispel myths about rhino horn’s medicinal value and build global pressure to enforce stricter wildlife trade regulations. Knowledge fosters empathy and drives consumer behavior away from illegal wildlife products. - Advocate for Stronger Legislation:
Supporting policies that tighten border controls, increase legal penalties for wildlife trafficking, and enhance international cooperation can disrupt illicit trade networks. Petitions, letter-writing campaigns, and supporting conservation-minded candidates all contribute to creating a more robust legal framework.FoundationWikipedia. - Fund Research and Innovation:
Contributing to research institutions focused on reproductive technologies, habitat restoration, and long-term monitoring enables scientists to refine IVF protocols, improve habitat connectivity, and better understand rhino ecology. Research underpins every aspect of species recovery.
Collective Impact
By combining financial support, advocacy, and sustainable behaviors, we bolster the multifaceted efforts required to secure a future for both white rhino subspecies.
The southern white rhino’s comeback demonstrates that strategic actions can pay dividends, while the northern rhino’s decline reminds us of the fragility of wildlife in the face of human pressures.
Our collective choices today will determine whether future generations will witness wild white rhinos or only recall them in history books.
