What is a giraffe? About basic status

Giraffes are artiodactyls that are classified in the order Mammalia, order Artiodactyla, family Giraffeidae, genus Giraffe. The scientific name is Giraffa camelopardalis. It is a very large animal, with a body length of 4.7 – 5.3 m and a weight of 800 – 1,930 kg. It is the most famous of all herbivores and is often used in illustrations. It often appears in the news.

IUCN Status(保全状況)ENDANGERED
Length(体長)4.7 – 5.3m
Weight(体重)800 – 1,930kg

What are the roots and origins of the giraffe?

The roots of the giraffe (Giraffa camelopardalis) trace back to a group of ancient ruminants that appeared approximately 20 million years ago (during the Miocene epoch).

About 20 million years ago

Ancestors of the Giraffidae family appeared

They spread across what is now Africa and Eurasia

Early giraffids did not have necks as long as modern giraffes

Their body shapes resembled those of deer or antelopes

Representative early species:

Prolibytherium
→ An ancient member of the Giraffidae family; it possessed large, horn-like projections on its head

About 14 to 7 million years ago

Evolution of the long-necked lineage

Due to environmental changes—

Transition from forest to savanna

Individuals that could utilize leaves from tall trees held an advantage

Long necks and long legs developed

However, this evolution was not driven solely by the need to “eat leaves from high places”;

It is believed there were multiple reasons, such as:

Spotting distant predators more quickly

Making it easier to find other members of the herd

Gaining an advantage in competition between males

About 1 million years ago to present

Taking on a form close to the modern giraffe

Long neck

Long legs

A heart capable of maintaining high blood pressure

A long tongue (approx. 45–50 cm)

These and other modern characteristics were fully established.

Giraffe ancestors had “short necks”

It was once thought that giraffes evolved by stretching their necks, but we now know that:

They have seven neck bones (cervical vertebrae), just like other mammals

Each individual bone became extremely long

In other words, the evolution involved:

❌ An increase in the number of neck bones

⭕ An enlargement of each individual neck bone

About classification

Giraffes are related to cows and are said to have diverged from a common ancestor with okapis 11.5 million years ago. There is actually more than one species of giraffe. There are many subspecies. The following variants exist: Each has a long history on Earth, and each location is different. Unfortunately, many of them are listed as endangered species.

The Kordofan giraffe is a giraffe found in Cameroon, Chad, Central Africa, and Sudan. Approximately 2,300 individuals live in the wild, but their numbers have declined dramatically and they are designated as an endangered species.

What is Cape Giraffe?

Cape giraffes are found in South Africa, Namibia, Botswana, Zimbabwe, Eswatini, and Mozambique. The wild population was announced to change to endangered species in 2016 at 31,500 individuals. It is said that without long-term conservation efforts, it will become extinct.

What is a Nigerian giraffe?

The Nigerian giraffe is also known as the Niger giraffe. Currently, there are only 400 individuals, so they are in urgent need of protection. Of course, this giraffe is also designated as an endangered species.

What is a reticulated giraffe?

The reticulated giraffe is a giraffe found in areas of Somalia and Ethiopia. This giraffe is also designated as an endangered species, but conservation efforts have begun and it is now strictly managed in national parks and zoos around the world.

What is the Northern Rhodesia giraffe?

The Northern Rhodesia giraffe is called the Luangwa giraffe. Their numbers are small as they only live in the southern Luangwa Valley of Zambia. It is said that there are only 550 giraffes left, and this giraffe is also designated as an endangered species.

What is Masai Giraffe?

The Masai giraffe is also called the Kilimanja giraffe. It lives in south-central Kenya and Tanzania, and is characterized by jagged, irregular leaf-like spots. This giraffe is Tanzania’s national animal, but it is also listed as an endangered species.

About giraffe habitat

Giraffes can only be found in the central part of the African continent. They are extinct in Mali, Eritrea, Guinea, Senegal, Nigeria, and Mauritania. For a mammal, they have long legs, are large, and have a pattern, so they stand out on land. They are often observed.

  1. Geographical Distribution

Giraffes are endemic to Africa, living primarily in sub-Saharan Africa.

Examples of distribution by country or region:

East Africa: Kenya, Tanzania, Uganda

Southern Africa: Namibia, Botswana, Zimbabwe

Parts of West Africa: Niger, Chad (very small areas)

  1. Environmental Characteristics

Prefers savanna, dry grasslands, and open woodlands.

They feed on the leaves of tall trees (such as acacia), so they require an environment with a moderate amount of trees.

Although they are often found near water sources, giraffes can go long periods without water.

  1. Habitat Conditions

Food Supply: Abundant leaves from acacia and other tall trees.

Wide Range: They move around in search of food and water, so they require large spaces.

Low Human Activity: Avoids the impacts of poaching and agricultural development.

  1. Habitat Status

In some areas, populations are declining due to deforestation, development, and poaching.

The International Union for Conservation of Nature (IUCN) classifies giraffes as vulnerable.

Conservation efforts are underway in protected areas and national parks.

feature is? What kind of creature is it?

The giraffe’s most distinctive feature is its long neck. They can and will eat leaves that are at a height that other animals cannot reach. This has the advantage of being able to quickly find and escape from natural enemies even if they are far away. Male giraffes of the same species cause “necking,” in which male giraffes fight by bumping their necks against each other. They are highly social and live in groups of about 10 to 20 individuals.

  1. Physical Characteristics

Body Size: Approximately 4.5-6m in length, 4-5.5m in height, and approximately 800-1,200kg in weight (males are larger)

Neck Length: Approximately 2m in length, adapted for eating leaves overhead

Coat Color/Pattern: Brown to orange spotted (patterns vary by individual and subspecies)

Legs: Both front and back legs are long, allowing them to run at speeds of over 50km/h

Horns (Oscicones): 2-5 small horns on top of head (hairy skin)

  1. Diet

Herbivore: Mainly eats leaves and young branches of acacia and tall trees

Feeding Method: Skillfully picks leaves using its long tongue (approximately 45cm)

Water: Most water is obtained from leaves; it rarely drinks water

  1. Behavior/Lifestyle

They are diurnal, active during the day, eating and moving around.

Distance Traveled: Travels over a wide area in search of food and water.

Rest: They often rest standing up, lying down for short periods.

  1. Sociality

They often live in groups (groups of 10-20 individuals are common).

Male-Male Fighting: They compete for rank by using their necks in a technique known as “necking.”

Breeding Season: The dominant male in the group mates with the female.

  1. Personality/Characteristics

They are timid but highly alert.

Their excellent eyesight and long necks allow them to quickly detect enemies from a distance.

They appear laid-back, but they will run quickly if they sense danger.

What will your personality look like?

Giraffes are very cautious. This is because they have natural enemies in Africa. Despite its large size, it has a very timid personality.

  1. Basic Personality

Timid and cautious

Excellent eyesight allows them to detect danger from afar

They will flee immediately if approached by humans or predators

Gentle and gentle

They live in groups and are usually calm and composed

  1. Sociality

Group Life

Live in small groups of 10-20 individuals

Males within the group compete for rank, but are generally cooperative

Male-Male Fighting

They compete for rank and breeding rights through “necking”

Mother-Child Relationship

Females are very attentive to and protect their young

  1. Relationships with Humans

Highly cautious but not aggressive

They will often flee when they sense danger

They can be observed calmly at zoos if approached slowly

What is the ecology of giraffes?

In the wild, giraffes eat leaves, twigs, and acacia trees, spending most of the day eating to maintain their large bodies. They usually rest and sleep while standing upright. For breeding, males neck each other to determine dominance and compete for females. The gestation period is 453-464 days, and the lactation period is 10 months. They are said to live for 25 years.

  1. Living Environment

Habitat: Savanna, dry grasslands, and open woodlands of the African continent

Tree abundance: Prefers areas with many tall trees (such as acacias)

Range: Travels widely in search of food and water

  1. Diet

Herbivory

Eats mainly leaves, branches, and fruit from tall trees

Eats dexterously with its long neck and tongue (approximately 45 cm) to pick leaves

Water Intake

Since it obtains moisture from leaves, it rarely drinks water

  1. Behavior

Activity Period: Diurnal (active during the day)

Rest: Often rests standing up, with brief periods of lying down

Migration: May travel several kilometers in search of food and water

  1. Sociality

Popular Group Life

Popular groups of 10-20 individuals are common

Most groups are centered around females and young, while males tend to live alone or in small groups

Dominance Competition

Males fight with each other using their necks to “neck”

Reproduction

Dominant males mate with females

  1. Breeding and Rearing

Gestation Period: Approximately 15 months

Birth: Gives birth to a single calf

Rearing: The mother protects and raises the calf for approximately one year

  1. Defense and Senses

Excellent eyesight, hearing, and sense of smell

Detects predators from a distance

Running Ability

When sensing danger, they can run short distances at speeds of over 50 km/h

Do giraffes have natural enemies?

The giraffe’s predator will be the lion. Children are also preyed upon by leopards, leopards, hyenas, and cheetahs.

Vocalizations

For a long time, giraffes (Giraffa camelopardalis) were considered animals that rarely made any sound. However, we now know that they do communicate with one another using low-pitched sounds and specialized vocalizations.

🌙 Low-pitched grunts (humming)

Low, droning, or rumbling sounds

Observed primarily at night

Believed to be used for communication and for keeping track of other giraffes’ locations

Includes frequencies so low that they are difficult for humans to hear.

🐣 Sounds made by calves

Young giraffes (calves) vocalize relatively frequently.

Sounds resembling a “baa” or bleat

Whistling or wheezing calls

Used to call for their mothers or when feeling anxious.

⚠️ Sounds of alarm

When sensing danger, they may:

Snort loudly

Make a short “huff” or snort

Emit a low grunt.

Why do giraffes rarely vocalize?

Possible reasons include:

Their long necks and the unique structure of their vocal apparatus

The wide spacing within herds, making visual contact the primary method of monitoring others

The need to remain quiet to avoid detection by predators.

Seasonal Activities

Since giraffes (Giraffa camelopardalis) inhabit the African savanna, their activities are governed more by the alternation between the rainy and dry seasons than by the four seasons. They do not hibernate and remain active year-round.

🌱 Rainy Season (roughly November to May, depending on the region)

A time when food is abundant and their range of movement expands

New leaves and foliage appear

They consume large amounts of leaves from trees such as acacia

Herds travel shorter distances

A favorable time for raising young

Key behaviors

🌿 Increased time spent foraging
🚶 Less travel to water sources
🦒 Rapid growth of calves

With abundant vegetation, the rainy season is a relatively comfortable time for giraffes.

☀️ Dry Season (roughly June to October, depending on the region)

A time of increased movement in search of food and water

Grass withers, so they rely primarily on tree leaves

They travel long distances to find water

Herds tend to congregate near water sources

Activity patterns are adjusted

Key behaviors

🌳 Feeding on leaves from tall trees
💧 Moving toward water sources
👀 Keeping a lookout for predators from a distance

Thanks to their long necks, giraffes can access leaves from tall trees even after other herbivores have depleted the lower vegetation.

Walking Speed

Although the giraffe (Giraffa camelopardalis) is a massive animal, it can move surprisingly fast by utilizing its long legs.

🚶 Normal Walking

Approx. 3–5 km/h

They move while walking slowly and searching for leaves.

They employ a unique gait known as “lateral sequence walking” (or pacing), where the front and hind legs on the same side move together.

🚶‍♂️ Brisk Walking

Approx. 8–15 km/h

They increase their speed when moving in a herd or sensing danger.

🏃 Running Speed

Top speed: Approx. 50–60 km/h

For a large herbivore, they are extremely fast over short distances.

However, they lack high endurance and are not built for running at high speeds for extended periods.

“Galloping Gait”

Unlike their normal walking style, when running, giraffes:

Extend their front legs far forward

Swing their necks back and forth to maintain balance

Cover ground rapidly with the long stride of their legs

About Giraffe Babies

  1. Birth

Gestation Period: Approximately 15 months

Size at Birth: Approximately 1.8m in height, approximately 50-70kg in weight

Appearance: Spotted from birth, with small, soft horns (ossicones)

  1. Growth

Walking Begins: Baby begins walking after its mother within a few hours of birth

Nursing Period: Breastfeeds for approximately 6-12 months

Post-Weaning: Baby gradually becomes independent while learning to eat leaves and young twigs

Height Growth: Grows to approximately half its height within the first year of life, and approaches adulthood over the course of several years

  1. Relationship with Mother

Living in a herd with its mother and protected from danger

Learns how to move and forage from its mother

Females in the herd sometimes watch over the baby

  1. Personality and Characteristics

Timid and cautious

Highly dependent on its mother, it will hide nearby if it senses danger

Curious, but still clumsy at running and using its neck

Why are giraffes an endangered species? What is the cause?

As explained above, most giraffe subspecies are designated as endangered species. Furthermore, it is listed in the Washington Convention, and international trade is strictly restricted. Giraffe populations have been halved and urgent conservation efforts are needed. Their population is decreasing due to the following reasons:

illegal hunting

Although giraffes are internationally protected, illegal hunting for their meat continues in Africa. As a result, the population has not recovered at all. Giraffe bones can be used for ornaments, so illegal poaching continues unabated.

habitat destruction

Habitat destruction is also a problem. In Africa in particular, rapid land development is progressing, creating a very harsh environment. They are now protected on a limited basis in zoos and national parks. Conservation events are also being held around the world.

Can giraffes be bred?

Giraffes are not very suitable for breeding because they are huge animals and are designated as an endangered species, so there are many restrictions. These animals require more protection than other animals, and urgent action is needed. It is safe to observe the actual rhinos on site.

  1. Legal and Management Restrictions

Giraffes are protected wildlife, and international trade is restricted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Even in Japan, private captivity is not permitted by law.

Only organizations with special permission, such as zoos, conservation facilities, and research institutions, are permitted to keep them.

  1. Ecology and Difficulty of Raising

Large and Powerful

Adults can grow to 4-5 meters in height and weigh 800-1,200 kg, so sturdy fencing and safety measures are essential.

Requires a large living space.

As herbivores with a wide range of movement, they require large areas, tall trees, and an environment where they can live in groups.

Unique Diet

They feed in large quantities, primarily on the leaves of tall trees such as acacia, so an adequate food supply is essential.

Vulnerable to stress

Captivity and changes in environment can cause loss of appetite and illness.

  1. Examples of captivity

They are kept in zoos around the world, often with extensive grounds, trees, and water areas.

In Japan, they are kept in many zoos, including Ueno Zoo and Higashiyama Zoo and Botanical Gardens.

In captivity, they live in groups and are thoroughly monitored for their diet and health.
