Here is our expert guide to the world’s largest land mammals, including key facts about the two elephant species and their natural habitat.
How many species of elephant are there?
There are two extant elephant species: the African bush elephant, also known as the African savannah elephant (Loxodonta africana), and the Asian elephant (Elephas maximus).
Some taxonomists propose that the African forest elephant (Loxodonta cyclotis) is a separate species to the African bush/savannah elephant, and other believe that there may even be three African elephant species with an additional one called the West African elephant. While the African elephants are closely related, the Asian elephant is quite distinct.

How to tell the different between an African and Asian elephant
Ears The African elephant’s ears are much bigger than those of its Asian cousin, extending above the shoulder. It’s said that the former’s ears are the same shape as Africa, while the latter’s look like India.
Tusks Both male and female African elephants grow long tusks, but only male Asian elephants do (and not all males). Some female Asian elephants grow ‘tushes’ – barely visible, stumpy tusks.
Head African elephants have more rounded foreheads, while Asian elephants have twin domes on their heads with an indent in the middle.

Trunk The tip of an African elephant’s trunk has two fingers or ‘lips’; the Asian elephant’s trunk only has one.
Back While the African elephant’s back is concave (with a small hollow in it), the Asian elephant’s is convex (slightly domed).
Size In general, African elephants are larger. Adult males weigh up to six tonnes, while male Asian elephants usually weigh no more than five tonnes.

How intelligent are elephants?
Elephants are the world’s largest land mammals – and, aside from the great apes (humans, gorillas, chimpanzees, bonobos and orangutans) – the most intelligent.

Are elephants dangerous?
They are well-known for living in matriarchal (female-led) social groups, and although elephants are respected and revered by people throughout their ranges in Africa and South Asia, they are also feared because they can be aggressive and dangerous.

When are elephants most dangerous?
Musth, pronounced ‘must’, is when males experience increases in testosterone levels of a factor of 60 or more. The changes prepare them for competing for females and make them much more aggressive. The condition is more pronounced in Asian elephants, and can last for up to 60 days. Elephants in musth carry their heads and ears higher than normal and make a characteristic rumbling sound. A bull elephant in musth can be extremely dangerous to anything that gets in his way.
Are elephants mammals?
Elephants are the world’s largest land mammal. They’re warm-blooded vertebrates that nurse their young with milk produced by mammary glands, and they’re hairy creatures (the hairs are just small and sparse, so they don’t look furry). That means they fulfil all the requirements to be mammals.

What do elephants eat?
Elephants eat a wide range of plant material, including grass, leaves, woody parts of trees and shrubs, flowers and fruits when available. After rain, they will dig for roots. Asian elephants feed on more than 100 species of plant, and both African and Asian elephants take crops such as millet. An adult needs to eat up to 150kg of food a day – that’s 50 tonnes a year!

How much does an elephant weigh?
African bush elephants are not just the largest elephants but the largest land animals in the world, weighing in at around 6000kg and standing 3.2m tall at the shoulder, while females are about 60cm shorter and half the weight. Male Asian elephants weigh roughly 4000kg with a shoulder height of 2.75m, while the 2000kg, 2.2m tall African forest elephant is the smallest elephant species.

The largest elephant ever recorded was an incredible 3.96m tall and weighed a staggering 10,400kg.
How much does a baby elephant weigh?
Baby elephants weigh around 100kg on average, heavier than most adult men, and some newborns have been as large as 120kg. Those are figures for Africa bush elephants – baby elephants of other species are naturally smaller.
What is a baby elephant called?

How long is elephant gestation?
Elephants have one of the longest known gestations of any animal. African elephants have a gestation period of 22 months, while Asian elephants have a gestation period of 18-22 months. Elephants will typically only give birth two or three times in a decade, and young elephants may suckle for a few years.
What do elephants use their tusks for?
Tusks are actually hugely elongated upper incisor teeth embedded deep in the elephant’s head (up to a third of a tusk is hidden from view). Elephant tusks have a variety of uses: as a tool to dig for food or water and to strip bark from trees; as a weapon in battles with rivals; and as a courtship aid – the larger his tusks, the more attractive a male elephant may appear to a female.

Can elephants be right or left-tusked?
Yes. Just as humans are right- or left-handed, elephants are known to use one tusk more than the other. This favoured appendage is sometimes referred to as the ‘master tusk’ and often appears more worn.

Do female elephants have tusks?
Male and female African elephants naturally have tusks, but only male Asian elephants grow them. However, this is changing, and an increasing number of African elephants are being born without tusks. Those that do still have tusks have much smaller tusks than in the past – the average size has halved in the last century.

Why are elephant tusks getting smaller? Because of hunting and poaching for ivory. The elephants with the biggest tusks are most likely to be targeted, so they get killed and aren’t able to pass on their big-tusk genes to future generations.
How long do elephants live for?
African elephants have a lifespan of up to 70 years in the wild, but tend not to live quite so long in captivity. Asian elephants have a shorter lifespan of around 48 years.

Do elephants live alone or in groups?
Both African and Asian elephants form female-led, tight-knit groups consisting of a dominant matriarch, her female offspring and other female relations plus their calves. Occasionally, groups of elephants will allow ‘strangers’ to join them. Living in groups makes individuals safer and allows them to devote more time to caring for and teaching the young.
Do elephants recognise their reflections?
Elephants can recognise themselves in mirrors. Scientists believe this is a sign of greater self-awareness. In one study, an Asian elephant called Happy repeatedly touched an ‘X’ painted on her forehead while looking in the mirror, an indication that she knew she was looking at her own reflection. Most animals will assume that a reflection is another animal, and look for it behind the mirror.

Do baby elephants suck their trunks?
Yes they do! As in all young mammals, an elephant calf’s sucking reflex, which prompts it to drink from its mother’s breast, is strong. And when a youngster is not feeding, it may suck its trunk for comfort, just as a human baby would suck its thumb.
Newborn elephants have little control over their trunks and must learn how to use them. They practise by exploring their environment – touching fellow herd members, their surroundings and themselves. They must then master the use of their trunks for feeding. With more than 50,000 individual muscle units in the trunk, it’s a complex skill to learn.
Though trunk-sucking is more common in the early stages of life, elephants of all ages do it, even big old bulls, usually when they are feeling nervous or unsure.
Sometimes an elephant that appears to be sucking its trunk is actually using it to smell, placing the tip inside its mouth after touching or sniffing dung or urine to assess pheromones produced by other elephants.
How good is an elephant’s memory?
Elephants have amazing long-term memories. Scientists studying three herds in Tanzania found that, during a lengthy drought, the two herds led by older matriarchs left the drought area in search of water, and more of their group survived as a result. The scientists concluded that these older females had remembered a drought that had occurred more than 30 years earlier and knew what to do. One female elephant also recognised zoologist Iain Douglas-Hamilton even though she hadn’t seen him for four years. Maybe it’s really true that elephants never forget.

Can elephants feel empathy?
Elephants appear to understand what other elephants are feeling. Experiments show that when one elephant is unhappy, others share their feelings, something known as ‘emotional contagion’. In these situations, they will go over to their ‘friend’ and comfort them, often by putting their trunk into the other’s mouth, something that elephants find reassuring. Elephants will also assist other injured elephants, and even appear to mourn their dead.

Do elephants have a sixth sense?
Elephants may be able to detect a thunderstorm from 280km away, and will head towards it, looking for water. In 2004, elephants appeared to head for higher ground before the Asian tsunami struck.

How much methane does an elephant produce?
Elephants produce a lot of methane gas as a by-product of digestion. Scientists estimate that the amount of methane they emit in one day would be enough to power a car for 32km.
