We will explain the characteristics, ecology, and habitat of the Asian elephant. Individuals are currently at risk of extinction due to savannah and deforestation. Asian elephants live in a region from Southeast Asia to South Asia, and there are many subspecies. In southern Asia, wild elephants have been domesticated since ancient times and used for transporting goods and for festivals, so they are very familiar to human life.

What will happen to the classification?
It has been revealed that the two existing elephant species, the African elephant and the Asian elephant, diverged genetically about 7.6 million years ago. It has since been revealed that African elephants and forest elephants diverged genetically at least 1.9 million years ago. Therefore, there are currently three types of elephants, and the African elephant is one of them.

feature is? What kind of creature is it?
Asian elephants are characterized by the fact that the wrinkles on their trunks are not very prominent. Also, compared to African elephants, there is a difference here in that the auricles are not large. The tip of the snout has one protrusion at the top, the front legs have five hooves, and the hind legs have four hooves. Basically, Asian elephants wander in search of food, but they only travel up to about 30km.

Because they live in forests, they tend to be cautious and introverted, keeping their distance from humans and other animals.
- Curiosity and Playfulness
Young individuals are extremely inquisitive.
They learn and socialize through touching and knocking down trees, playing in water, and bathing in mud.
What is the ecology of Asian elephants?
Asian elephants drink 100 – 300 liters of water per day and eat large amounts of fruits and plants. The reproductive form is viviparous. Males fight over females that are in heat, and the gestation period is about 660 days. They give birth to one cub at a time, and the lactation period is about two years. The lifespan is said to be 60 to 80 years.

There are subspecies of Asian elephants.
Did you know that there are subspecies of Asian elephants? The following variants exist: I will introduce each of them. We will briefly explain the situation of Sri Lankan elephants, Indian elephants, Sumatran elephants, and Borneo elephants. As is often reported in the news, herds are in critical condition due to deforestation. Their tusks are being targeted, and their way of life in nature is threatened.
| Name：名前 | scientific name：学名 | Habit：生息地 |
| Sri Lankan elephant スリランカゾウ | Elephas maximus maximus | Sri Lanka スリランカ |
| Indian elephant インドゾウ | Elephas maximus indicus | India インド |
| Sumatran elephant スマトラゾウ | Elephas maximus sumatranus | Indonesia インドネシア |
| Borneo elephant ボルネオゾウ | Elephas maximus borneensis | Indonesia、Malaysia インドネシアとマレーシア |
sri lanka elephant
The Sri Lankan elephant is an elephant native to Sri Lanka. At the shoulder height he is the largest subspecies reaching 2-3.5 m and weighs 2,000-5,500 kg. The skin is dark with large, distinct patches of depigmentation on the ears, face, trunk, and abdomen. Many elephants died during the Sri Lankan civil war. Furthermore, from 1999 to 2006, nearly 100 wild elephants were killed every year to protect crops and homes, and the elephants are on the verge of extinction.
indian elephant
Indian elephants live mostly in India, and are approximately 3.2 m tall at the shoulder and weigh up to 5,400 kg. The elephant is characterized by a concave forehead, his two large ears that are folded to the side, and smooth gray skin. Wild populations have declined by at least 50% and require urgent conservation.
sumatran elephant
The Sumatran elephant is native to the Indonesian island of Sumatra. Its most distinctive feature is that it has a single finger-like protrusion at the tip of its body. The Sumatran elephant’s shoulder height is 2-3.2 m, its weight is 2,000-4,000 kg, and its skin color is lighter than that of Sri Lankan and Indian elephants. 69% of Sumatran elephant habitat has been lost due to rapid land development, and incidents of elephants entering residential areas and being electrocuted or poisoned are rapidly increasing.
borneo elephant
The Borneo elephant, also known as the Bornean elephant or Borneo pygmy elephant, is a subspecies of Asian elephant that lives in Indonesia and Malaysia, northeastern Borneo. His personality is surprisingly quiet and passive. It is somewhat smaller than the Asian elephants. With rapid land development, food shortages are becoming more serious, and their numbers are declining.
Is the Asian elephant an endangered species?
The estimated population of Asian elephants is less than 50,000. Unfortunately, it has been designated as an endangered species by the IUCN and is also listed in Appendix I of the Washington Convention, which places strong restrictions on international trade. Why have African elephants been designated as an endangered species? Let me explain why. It turns out that the problem is caused by us humans. For this reason, various projects and activities such as forest protection are currently underway.
Overhunting for ivory continues
Ivory is the reason why wild elephants have been overhunted in large numbers by humans. Ivory is a beautiful material and is highly sought after in the arts, crafts, and manufacturing industries, and sells for a high price. In some regions, illegal poaching and overhunting of living creatures has progressed in society without laws, and elephants are being killed one after another by humans.
Rapid progress in land development
Southeast Asia, South Asia, and Africa are all experiencing rapid economic development and land development. As I explained above, elephants eat large amounts of grass, so if there are no trees left in any place, it means that they will no longer be able to reproduce and survive.
Elephant Day is set
“World Elephant Day” was established on August 12, 2012 by Canadian film director Patricia Sims and a Thai conservation organization to call for the protection of elephants around the world. The purpose is to overcome the threat of extinction by collecting donations and exchanging information from friends to protect the species. We are currently asking for help to protect the declining population of elephants.
Can elephants be kept?
Can elephants be kept? It’s very difficult. First of all, all elephants are endangered species and are strictly protected. It is also wise to keep in mind that it is extremely difficult for the average person to raise them as they require a large amount of food. It is best to see them at a zoo or at a local national park.
- Body Size and Dietary Constraints
Weight: African elephants weigh 4-7 tons, while Asian elephants weigh 2-5 tons.
Diet:
Eat 100-200 kg of plants per day.
Water requirements: 150-300 liters per day.
Exercise: In the wild, elephants can travel tens to hundreds of kilometers, requiring a large area of land.
→ Securing the space, food, and water required in an average household is practically impossible.
- Sociality and Psychological Stress
Elephants are highly sociable and intelligent animals.
Matrilineal and intra-group social relationships are important, and isolation can cause stress and damage their health.
Lack of opportunities for play and learning can lead to behavioral abnormalities (repetitive behaviors and aggression).
→ Solitary captivity places a significant psychological burden.
- Legal Restrictions
Elephant captivity is strictly regulated in many countries.
Internationally, trade is controlled by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), making it nearly impossible for individuals to keep elephants.
- Actual Examples of Captivity
Mainly kept in zoos and safari parks
Sufficient exercise areas
Professional animal care staff (veterinarians and trainers)
Appropriate diet, social interaction, and health management
They have also been kept in circuses and for tourism, but problems with stress and abuse have been noted.
- Summary
Elephants are highly unique in terms of their physique, diet, sociality, and intelligence.
Keeping them in an ordinary home is impossible.
Keeping them is only possible in facilities with large premises, specialized staff, and a comfortable social environment.
Protecting wild elephants and preventing illegal trade is important.
