Proboscidea is an order containing only one family of living animals: Elephants. There are three living species of Elephants (African Bush Elephant, African Forest Elephant, and Asian Elephant) which are currently on record. All Elephants exhibit a long nose or mouth parts called a Proboscis which is used for feeding and defending territory. The following listings shows both Living and Extinct species of Proboscidea.
Some features of Proboscideans
Long prehensile nose (Primarily used for feeding and gathering). The trunk may also be used in socializing and courtship rituals.
Elongated upper canines to form large tusk. These tusks may vary in size and length depending on the species and sex.
Large body with wrinkled skin (adult weight above 3000 kg)
Disproportionately large ear lobes (capable of radiating heat and focusing sound waves from the environment)

African Elephants belong to the species Loxodonta. Although they may appear to be of the same species as the Asian Elephant, they are not.. The African and Asian elephants do not belong to the same Family, and therefore cannot be interbred. There is one documented case of interbreeding with an Africal Bull and Asian Cow. However due to complication, the offspring did not survive beyond 2 weeks.

All species of Loxodonta are African and live throughout Africa, from the Sahara deserts to the Congo basins.
There are 2 existing sub-species of Loxodonta that live in Africa:
African Bush Elephant (Loxodonta africana)
African Forest Elephant (Loxodonta cyclotis)
Bush and Forest Elephants were formerly considered subspecies of the same species Loxodonta africana, but now they are considered to be 2 distinct species.
The Asian Elephant (Elephas maximus) is considered to be the largest living land animal in Asia.
There are four living subspecies of the Asian elephant:
Indian Elephant (Elephas maximus indicus)
Sri Lankan Elephant (Elephas maximus maximus)
Sumatran Elephant (Elephas maximus sumatrensis)
Borneo Elephant (Elephas maximus borneensis)
Female elephants live in small groups called matriarchal society, where the group is led by the oldest female (Matriarch). The herd primarily consists of sisters, nieces, aunts. When a bull reaches sexual maturity at 9-15 years of age, its pushed out of the group by the females to prevent inbreeding. The bull will then seek out a new herd and mate with the mature females. The gestation period for a female is 18–22 months, and the female gives birth to one calf.
An early extinct mammoth.
The woolly mammoth (Mammuthus primigenius), is an extinct species of the Proboscidean order. This mammal is known from bones and frozen carcasses from northern North America and northern Eurasia with the best preserved in Siberia.
Woolly mammoth extinctions are attributed to dramatic climate change within a short period of time. Its commonly believed that sub-species of woolly mammoths existed even during the reign of modern mans, perhaps as late as 2500 BC.
