The elephant is a four-legged mammal. They belong to the kingdom Animalia. They are the largest terrestrial animal. They are herbivorous and eat grass, wood, fruits and pulp. After reading this article you will be able to distinguish between two species of elephants and their characteristics.
Species of elephant
There are two main species of elephant: African elephants (Loxodonta) and Asian elephants (Elephas Maximus). African elephants have two subspecies: The African bush elephant (Loxodonta Africana) and the forest elephant (Loxodonta Cyclotis). They differ from each other in size and habitat. There are three subspecies of Asian elephants: Indian (E. m. Indicus), Sri Lankan (E. m. maximum), and Sumatran (E. m. sumatranus). The Indian elephants are spread wide in the continent. The Sumatran elephants are the smallest found in the Indonesian island Sumatra, which contain a large number of animals and plant species. The Sri Lankan elephants are the largest subspecies in size. But still, scientists argue that if there are enough variations that create them a separate species.
The White Elephant
The white elephants are very rare. They are found in Thailand, Burma, and rarely in Africa. Although they are not a separate species but differs from others because of their skin colour. Their skin colour is not pure white. They have a reddish-brown colour, which turns out pink when they are wet. These elephants have important in their respective areas because of their distinct skin colour. Whenever a white elephant is found in Thailand, it is presented to the ruler of the time. And the more white elephants the rulers have, the stronger their position in society. Similarly, in Burma, they are considered a sign of good fortune.
Elephants live in tropical and sub-tropical areas of Africa and Asia. Mostly they live in forest, woodlands, and savannas, but some of them also live in deserts and mountains. Woodland is a land covered with trees, shrubs, and grasses and has plenty of sunlight. They widely change their habitat with their needs. They used to migrate from one place to another in search of food and water. They also change their habitat because of weather changes.
African elephants live mostly in savannas and tropical forests. Savannas are full of grasses and some scattered trees. The average rain in savannas is 20 to 50 inches each year. Some African elephants also live in deserts and mountains, and the desert elephant can travel up to 60 miles in a day in search of food.
Asian elephants habitat includes plains, deciduous forest, evergreen forest, and cultivated lands. In hot weather, they prefer to migrate towards watery areas to prevent dehydration.
Unique Body Features
They have a distinct feature called "trunk" also called a proboscis. The proboscis is an elongated nose of vertebrates. It is the fusion of the upper lip and nose. Elephants use their trunks to carry food and water to their mouths and to catch things. There are two finger-like extensions at the end of the trunk by which Elephants use to grab food or objects. The trunk of an elephant has 40,000 muscles which make it a versatile and delicate organ.
Elephants have 26 teeth: 12 molars, 12 premolars and a set of enlarged growing teeth known as "tusks". Almost all African elephants have tusks whereas only some male Asian elephants have tusks. Tusks are elongated incisors in elephant. They are deeply rooted and most of the part is made by dentine (a hard, bony tissue) which is also known as "ivory". Tusks of elephant are only one set that keeps growing throughout their life. Elephants replace their teeth six times during their life cycle. Tusks replace milk teeth at 6 to 12 month of age of an elephant and grow almost 17cm in a year.
Elephants have unique ears which work like a cooling system for them. The ear is 6 feet from top to bottom and 5 feet wide. The advantage of large ears is that they can pick up sound from a distance. The ears of African elephants are bigger than their Asian cousins and look like the continent of Africa. The average weight of an ear is nearly 100 pounds. Elephants don't have enough sweat glands, so they use their ears to regulate their body temperature. Their ears act like fans and by flapping they provide air to the rest of the body of an elephant.
Communication in Elephants
Elephants communicate through vocal calls which include roars and rumbles. These calls convey specific massage. When elephants try to save calves from danger, they make a special call. Hearing this, the rest of the elephants also come around the calves to protect them. The pitch of the sound depends on their mood.
Elephants produce low-frequency sounds that the human ear cannot hear. These soft sounds are so powerful that they can be heard from a long distance and carry the message to the elephants that are a short distance away. These low sounds are called infrasonic noises. They also express their feelings and emotions of joy and sorrow by making noises.
Communication Through Vibration
Communication through vibrations is expressing the message through mechanical vibrations of the substrate. In Elephants the substrate is earth. With the help of this communication, Elephants can warn each other of danger from miles away. The soft pads of feet produce seismic vibrations which they detect through their proboscis and feet.
Elephants possess various modifications suited for vibratory contact. For example, the pads of the feet contain cartilaginous nodes. The ears of the Elephants contain annular muscle, which helps them to hear seismic signals.
Reproduction and Life Cycle
Elephants become sexually mature at 14 or 15 o age. Sexual maturity age depends on nutrition. Female produces a single baby (rarely twins). The gestational period is 20 to 22 months long. A Female with good health and habitat gives birth every three to four years. The weight of a newborn baby is usually 100kg. The infants can stand shortly after birth. They are polygynous: in which a male can have over one female for mating. But it's not that easy. They have to be dominant on other males to attract more female elephants.
Musth is a condition in which a male elephant shows very aggressive behaviour. This occurs once a year and has a huge impact on the behaviour of elephants. This behaviour change is because of hormonal reasons. In musth, the level of testosterone increases up to 50 times than normal and some physiological changes occur in elephants. Elephants become more dangerous and aggressive in musth. Draining of urine from legs also noticed in musth. Secretion from temporal glands occurs, which are located midway between the ears and eyes. The period of musth can last from a few weeks to months. But no one still knows the full truth of musth. Every researcher and elephant keeper gives a different opinion about it.
Signs of musth
In musth, elephants show strange behaviour and become dangerous. The most common signs from which we can recognise "the musth elephants" are: alertness, spreading of ears, blowing trunk, swollen trunk base, the foreskin of the penis become white and greenish, and destructive behaviour towards other elephants and humans.
How African and Asian Elephants are Different from Each Other
|Features||African elephants||Asian elephants|
African elephants are bigger in size and weigh around 5,000 to 14,000 lbs.
Asian elephants are slightly smaller and weighing between 4,500 to 11,000 lbs.
African elephants have two fingers like projections at the end of their trunk.
Asian elephants have only one.
African elephants have large ears which look like the continent of Africa.
Asian elephants have small and rounded ears.
Almost all African elephants have long tusks which grow in size with time.
Only some male Asian elephants have long tusk while females have small tusks which are not extended outside called "tushes".
African elephants have looser and more wrinkled skin.
Asian elephants have harder and less wrinkled skin.
Importance of Elephant
Support other animals
Elephants are also known as ecosystem engineers. They maintain the ecosystem of their habitat, which helps other animals to thrive. In dry and hot weather, they dig the land to make watering holes from which other animals can drink water. They find and dig underground water with the help of their trunk, tusks and feet.
They Attract Tourist
Being a huge and valuable animal, they attract tourist toward themselves. People always want to watch and ride on them due to their friendly behaviour and unique body type.
Distribution of Seeds
Many plants and trees rely on elephants for their survival. As elephant eat seeds of plants and trees and these seeds need to pass through the digestive system of an elephant to germinate. Elephant's dung contains these seeds and spread them from one place to another.
They play a significant role in shaping their habitat. They make pathways for other animals in the forest by grazing. They make paths for sunlight to reach on the ground in the forest, essential for many trees and plants. Even footprints of elephant have an advantage: when the holes of the footprint filled with water; they provide shelter to tadpole and other small organisms.
