FOR AGES 3 YEARS TO 18 YEARS
We have all looked at the large body and gigantic teeth that elephants have and wondered how these animals came into being. Research shows that animals of the Proboscidean order, to which elephants belong, have tread earth for millions of years. Although all but one families of the proboscidean order have now become extinct, evidence collected from the study of fossils reveal how these animals have evolved into becoming what we see them as today.
The only living family of the order is Elephantidae, which consists of three species of elephants. Two of these species are native to Africa, and one is native to Asia. The species are differentiated by their size and physical features. One of the rather unfortunate facts is that all modern species of elephants are now facing extinction. Keep reading to learn more about the proboscidean order and elephants!
Proboscidea is an order of animals. The only surviving members of the order Proboscidea are elephants.
The Proboscidea elephants are classified as mammals. The more formal term for the class is Mammalia.
Unfortunately, the population of proboscideans is decreasing in the world. At present, there are only around 5,00,000 elephants left on earth.
Proboscidea elephants live in forests, grasslands, and woodlands, where they have access to plenty of food.
The two living species of the Proboscidea order are African elephants and Asian elephants. These two species live in different parts of the world, as the names suggest. African elephants are common in Zimbabwe, Tanzania, Kenya, and Botswana, among other places within Africa. Asian elephants are found in India, Vietnam, Cambodia, and Nepal.
Many million years ago, there were many proboscideans in the world. Most of those animals have now become extinct species.
The Proboscidea range is filled with large groups of elephants trudging around peacefully. These giant mammals are sociable and live in large groups which move from one forest to another in a very organized manner.
An elephant's lifespan depends on its species. An Asian elephant has the average life expectancy of around 48 years, while an African elephant has an average lifespan in the range of 60-70 years. The life expectancy is also dependent on the conditions of the areas of the world that witness the heaviest Proboscidea distribution.
Proboscideans are mammals, which means that they are viviparous animals, just like humans. A member of the Proboscidean family can only give birth to one offspring at a time.
A female elephant's gestation period is of around 18-22 months, after which it gives birth to a baby elephant. Asian elephants typically tend to have smaller gestation periods than African elephants.
According to the IUCN Red List, the conservation status of the proboscidean Asian elephant is 'Endangered.' On the other hand, the conservation status of the African elephant species is termed as 'Critically Endangered.' This essentially means that neither of the living species of Proboscidea elephants in the world have large populations at present. This places these elephants at a definite risk of becoming extinct. Hence, many conservation efforts are underway, ensuring that these elephants are not stripped off their natural habitats!
Proboscideans have different features depending on the specific species. The early proboscideans did not have tusks or large ears. These features are absent in absent in fossil remains of the early species, which shows evolution. Mammoths, on the other hand, were characterized by their gigantic bodies, large ears, long trunks, and two huge incisor teeth, which were named tusks.
A modern-day African elephant is differentiated from an Asian elephant through some features. For example, the back of an African elephant is concave while that of an Asian elephant is convex. African elephants also tend to be larger than Asian elephants. Both have long trunks and tusks, alongside large ears. The size of the elephant's ears is also dependent on its species. Elephants use their tusks to eat and pick up things.
While mammoths cannot be called cute simply because of just how huge they were, the living species of the proboscidean order are very cute. The large, floppy ears and long tusks add softness to the elephant's features, while the tusks impart a regal look!
Elephants communicate through sounds. These sounds are created through the mouths and trunks.
The length of the living proboscidean species remains in the range of 18-24 ft (5.4-7.3 m).
An African bush elephant can run at the speed of 24.8 mph (40 kph). This is also estimated to be the speed at which mammoths could run!
The Proboscidea size clearly shows that these animals are not exactly feathery-light! The weight range of these animals is a stupendous 5000-14000 lb (2268-6350 kg)!
Male and female elephants are called bulls and cows respectively!
A baby elephant is called a calf!
The Proboscidea diet is assumed to always have been herbivorous in nature. All the food that elephants eat and love can be found in the forests that they inhabit. Such food would include small plants, leaves, fruits, and vegetables!
When in Africa or Asia, it is easy to look at an elephant and assume that it must be very dangerous. While we definitely shouldn't take these animals and their strength lightly, it is also important to remember that they are friendly animals that don't hurt people unless they sense a threat.
Proboscidean animals are undoubtedly cute, but they eat a lot of food and require a lot of space. Furthermore, elephants are facing threats of extinction, which is why they shouldn't be domesticated.
Evidence of the oldest proboscidean dates back to the early Palaeogene period of the Earth.
Mammoths, along with most other early proboscideans, are now extinct.
Mammoths become extinct around 4000 years ago!
The average Proboscidea life expectancy is of 48-70 years!
Currently, African elephants and Asian elephants are the only living members of the Proboscidea order.
The earliest evidence of animals belonging to the Proboscidea order dates back to the Palaeogene period of this planet. It is believed that the earliest members of the order were not any bigger than large pigs. At the present day, elephants are the largest mammals on Earth.
The early proboscideans did not have large incisor teeth or tusks. The animals evolved in such a way in order to be able to defend themselves. Other evolved traits would include the large, flap-like ears and the immense size!
