What kind of animal is the white rhino? We will explain its characteristics, ecology, and habitat. The white rhino is a subspecies of rhino found in Africa, and as its name suggests, it is characterized by its relatively white body. Unfortunately, the white rhino is also on the brink of extinction and is in a very dangerous situation.
What is a White Rhino? Basic Stats
White rhinos are mammals of the order Perissodactyla and family Rhinidae. Their English name is White Rhinoceros/Square-Lipped Rhinoceros, and their scientific name is Ceratotherium simum. They are 3.5-4.2m long, 50-70cm long tails, and weigh 1,500-3,600kg. Most of them live in Africa and South Asia. They are large animals and are currently active in Africa. They are a very common animal, appearing in animal horoscopes and illustrations, and are said to be auspicious animals.

Rhino habitat
Rhinoceroses are found in the eastern and southern parts of the African continent (Uganda, Eswatini, Kenya, Zimbabwe, Namibia, Botswana, Mozambique, South Africa, the Democratic Republic of the Congo, Sudan, South Sudan, and are considered extinct in Chad and the Central African Republic.
- Geographic Distribution
White rhinos are found throughout the African continent. Each subspecies has a different habitat.
Northern White Rhinoceros (C. s. cottoni)
Currently almost extinct in the wild (formerly inhabited northeastern Democratic Republic of the Congo and northern Uganda).
Very few remain in the wild, with only a few protected individuals remaining.
Southern White Rhinoceros (C. s. simum)
Main Distribution: Southern Africa
Namibia, Zimbabwe, South Africa, Botswana
Stable habitat within protected areas and national parks.
- Habitat Characteristics
Grasslands/Savannas: Prefers vast, open areas.
Wetlands and riverside grasslands: Areas with access to water sources and fresh grass.
Soil and Water: Water and wetlands are important for mud bathing and thermoregulation.
Altitude: Mainly lives in low- to mid-altitude plains.
- Ecological Relationships
Herbivory: Mainly lives in areas with abundant grass.
Pack Living: Forms herds in large, open areas and forages, rests, and guards.
Migration: Moves between areas with grass and water during the dry and rainy seasons.
What are its characteristics? What kind of creature is it?
The white rhino is the largest of the rhinos and is covered with thick, hard skin like armor. It has no hair on its body, but there is a little hair at the end of its short tail. Its body color is gray or brown, and it often plays in the mud. Rhinos have one or two thick horns on their heads, and the shortest can be 25 cm long, while the longest can be 1.5 m long. They usually live alone and live in savannas, forests, grasslands, bushlands, and wetlands.
- Physical Characteristics
Characteristics Details
Body Type: Sturdy, large body. Rounded, suitable for herbivorous living.
Body Length: Approximately 3.5-4 m
Height: Approximately 1.7-2 m
Weight: Approximately 1,400-3,600 kg (one of the largest among large herbivorous mammals)
Hair Color: Gray to light gray, with little hair
Horns: Large front horns and short rear horns. Made of keratin, they are used for defense and fighting.
Mouth: Wide, flat mouth (shaped for efficiently cutting grass)
Tail: Short, with hairy tip
Characteristics: Specialized for herbivorous living, often preferring to live in groups, gentle and not aggressive (although they will attack if they sense danger).
Appearance: “Gray, huge, grass-eating, flat-mouthed, gentle-looking savanna giant.”
- Behavioral and Ecological Characteristics
Diet: Herbivorous (has a flattened mouth for efficiently cutting grass)
Behavior: Diurnal, often living in groups
Sociality: Unlike the solitary black rhinoceros, white rhinoceroses sometimes live in groups (especially females and young animals)
Defensive Ability: Their horns are used for attack and defense. They are generally gentle, but can become aggressive when they sense danger.
Bathing/Mud: They frequently bathe to regulate their body temperature and prevent parasites.
- Personality and Behavioral Characteristics
Gentle and herd-oriented
They will flee when they sense danger, but will use their horns to defend themselves when protecting their mother or the herd.
They are less territorial than black rhinoceroses.
They are very docile while feeding, but become wary when approached.
What is their personality like?
Compared to black rhinos, white rhinos are more docile and have a gentle personality. White rhinos live in open grasslands and shrublands, and occasionally form groups of 10 to 20. They tend to live in a fixed range of 0.75 to 8 km2.
- Basic Personality
Gentle and Gentle
Generally docile, with little aggression toward humans and other animals
Typically live in groups and are social
- Response to Danger
Can be defensive
Mothers become aggressive when protecting their young
When threatened, they defend themselves with their horns and body.
In the wild, they take defensive action when large predators (lions and crocodiles) approach.
- Sociality in Groups
Primary Personality
Live in small groups of mothers and young, or in groups of young females.
Forage and rest cooperatively within the group.
Rarely act alone like the black rhinoceros.
- Personality During Feeding and Activities
Gentle and Gentle
Move very little while grazing and are not aggressive.
Forage calmly with members of the group.
What is the ecology of rhinos?
Rhinos are herbivores, living by eating grass, leaves, fruits, etc. Breeding occurs all year round, with a lactation period of about a year and a gestation period of another year. Females can give birth to one baby at a time. Females reach sexual maturity at 6-7 years, and males at 10-12 years. They are said to live for about 45-50 years.
- Habitat
Region: Primarily southern Africa (Namibia, Zimbabwe, South Africa, Botswana)
Environment: Savanna, grassland, wetlands
Prefers to stay near water sources for bathing, mud bathing, and drinking
- Diet
Herbivore (Grassbrusher)
Uses a wide, flat mouth to efficiently cut grass from the ground
Eats mainly short grasses of the grassland
Diet: Consume 50-60 kg of grass per day
Foraging Time: Mainly active during morning and evening periods
- Behavior
Live in groups
Small groups of mothers and calves, groups of young females, etc.
Males may have individual territories, but are less aggressive than black rhinos
Diurnal
Foraging and movement are primarily during the day
Bathing and mud bathing are also performed during the day
Migration Range
Moves to areas with grass and water during the dry and rainy seasons
Travels over vast grasslands, traveling distances measured in kilometers
- Breeding and Rearing
Breeding Season: Year-round
Gestation Period: Approximately 16–18 months
Birth: Usually one pup
Growth of the Pup
Mothers are responsible for approximately 2–3 years
Pups learn to forage and bathe in the mud within their mother’s herd.
Do rhinos have any natural enemies?
Rhinos are powerful animals, so they have no natural enemies. However, small or sickly rhinos are targeted by predators such as lions and leopards. Rhinos can run away at speeds of about 30km per hour, so they are not easy to catch.
About White Rhino Calves
This article provides detailed information on the characteristics, growth, and ecology of white rhino (Ceratotherium simum) calves.
- Birth
Gestation Period: Approximately 16-18 months
Birthing Period: Year-round, but most commonly occurs after the dry season (when grass is plentiful)
Number of Pups Born: Usually 1
Birth Length and Weight: Approximately 1.2 m, Weight: Approximately 40-65 kg
Appearance:
Coat Color: Light gray to brown
Horns: Small and still soft (will harden as they grow)
Her head and body are rounded, and they live closely attached to their mother
- Growth of Cubs
Growth Characteristics by Age: 0-6 Months: Closely attached to their mother, fed mainly on breast milk, and occasionally munching on leaves and grass. 6 Months-1 Year: Weaning begins, and they begin grazing with their mother. 1-2 Years: They learn foraging, mud bathing, water bathing, and guarding behavior from their mother. 2-4 Years: Their bodies and horns grow larger, and they gradually prepare to become independent from their mother. 4-5 Years: They become independent and adapt to their own herd and territory (males are particularly active during the breeding season).
- Behavior of Young Animals
Living under the protection of their mother
Young animals stay safe by hiding behind or to the side of their mother
Learning Behavior
They learn how to forage, bathe in mud and water, and be on guard from their mother and her pack
Play
They develop strength and balance through light collisions using their horns and bodies
Danger Avoidance
They learn how to escape and hide under the guidance of their mother
- Physical Characteristics
Small, rounded body
Coat color is lighter and softer than that of their mother
Horns are still small and not fully developed for defense
Large eyes are adapted to guarding their surroundings
Are rhinos endangered?
As explained above, most subspecies of rhinos are designated as endangered. They are also listed in the Washington Convention, and trade is classified and severely restricted. The reasons for this are as follows. They are in a critical situation.
Illegal hunting
Rhinos are protected internationally, but illegal hunting for their horns continues in Asia and Africa. This has prevented the population from recovering at all. Rhinos horns are traded at higher prices than cocaine, heroin, and gold, making them profitable.
Habitat destruction
Habitat destruction is also a problem. Rapid land development is progressing especially in Southeast Asia, making the environment very harsh. They are now protected in limited zoos and national parks. Events for conservation are also held around the world.
Can rhinos be kept as pets?
Rhinos are large animals, and there are many restrictions as they are designated as endangered, so they are not very suitable for keeping. They need protection more than other animals, so immediate action is needed. It is safe to see the actual rhinos on site. At the zoo, male and female Southern White Rhinos are on display, and you can check the park map at the top of the site. Once you enter the zoo, there are times when you can interact with the animals, so you can access the facility by bus or train and enjoy the dogs and cats.
- Difficulty of Raising
Key Points Details
Size: Adults measure approximately 3.5-4 m in length and weigh approximately 1,400-3,600 kg. They are very large and powerful.
Living Environment: They are adapted to living in large herds and traveling in savannas and grasslands. It is impossible to replicate this in homes or small facilities.
Exercise Demand: Because they travel and forage over a wide area, cramped environments can cause stress and health problems.
Diet: They are herbivores, requiring large amounts of grass. They must be provided with tens of kilograms of grass or hay every day.
Personality: Generally gentle, but can become defensive when they sense danger. Due to their heavy weight, there is a high risk of accidents.
Law: In many countries, wildlife protection laws strictly regulate capture and captivity, and private ownership is prohibited. - Examples of Captivity
Keeping in Zoos and Safari Parks
Horses and mother-calf groups are managed on large land areas.
Keepers must provide grass, medical care, and weight management.
Kept for breeding, conservation, and educational purposes.
Keeping at home or privately is practically impossible.
Nearly impossible in terms of environment, diet, safety, and legal requirements.
- Ideal Environment
Large land area: Recreating grasslands or savannas on at least several hectares.
Food security: Provide 50-60 kg of grass or hay daily.
Bathing and mud bathing areas: Essential for temperature regulation and skin care.
Safety management: Control contact with humans and other animals.
Veterinary care: Constant health monitoring of large mammals is required.
