Elephants are magnificent creatures, known for their intelligence, social bonds and of course, their iconic tusks. These elongated teeth are not just for show—they serve crucial functions in an elephant’s life. Here are ten fascinating facts about elephant tusks that you might not know!
1. Tusks Are Actually Teeth
Elephant tusks are elongated incisor teeth that grow continuously throughout an elephant’s life. They are made of dentin, a dense, bony tissue, and are covered in a smooth outer layer of enamel. Unlike human teeth, which stop growing at a certain point, elephant tusks continue to develop, making them a vital part of the animal’s anatomy and survival.
2. Both Male and Female Elephants Can Have Tusks
In African elephants, both males and females typically have tusks. However, in Asian elephants, only some males develop prominent tusks, while females usually have small or no tusks at all. This distinction is due to genetic differences between species and has also been influenced by selective pressures such as poaching.
3. Tusks Serve Many Purposes
Elephants use their tusks for a variety of functions, including digging for water in dry riverbeds, stripping bark from trees for food, lifting objects and defending themselves against predators and rivals. Tusks also play a role in social interactions, such as displays of dominance during mating season, where male elephants use their tusks to compete for mates.
4. Tusks Keep Growing
Elephant tusks continue to grow throughout an elephant’s life. In fact, older elephants tend to have larger tusks, making them prime targets for poachers, unfortunately. The growth rate varies, but on average, tusks can grow about 17cm (7 inches) per year. Since they are always growing, elephants continuously use them to prevent excessive length that could hinder movement.
But how big do elephant tusks get? The longest elephant tusk recorded was an impressive 3.5 meters (11.5 feet) long (the same length as a small car). The heaviest tusk to be recorded, weighed almost 120kg (264.5 lbs). Here’s a list of Africa’s 10 biggest tuskers.
5. Elephants Are Either Right-Tusked or Left-Tusked
Just like humans are right- or left-handed, elephants tend to favour one tusk over the other. The dominant tusk, called the “master tusk,” is usually more worn down due to frequent use. Researchers can often determine which tusk an elephant favours by observing its shape and level of wear, much like analysing a well-used tool.
6. Tusks Can Be Broken or Lost
Elephants sometimes break their tusks during fights, when foraging or through accidents. If an elephant loses a tusk, it does not grow back, but the remaining tusk will continue to grow. In some cases, a broken tusk can become infected, leading to serious health problems. This is why tusk injuries are closely monitored in conservation areas.
7. Ivory Trade Has Decimated Elephant Populations
The demand for ivory has led to extensive poaching of elephants. Despite international bans on the ivory trade, illegal hunting continues to threaten elephant populations, especially in Africa. Countries and conservationists are working to combat this crisis through stricter enforcement of laws, habitat protection, and education about the devastating consequences of the ivory trade.

8. Some Elephants Are Naturally Tuskless
Due to selective pressure from poaching, more elephants are being born without tusks. In some heavily poached populations, a significant percentage of elephants now lack tusks entirely. This is an example of how human actions can influence the evolution of a species, although tusk-less elephants may face challenges in foraging and self-defense.
9. Tusks Can Reveal an Elephant’s Age and Health
The size, shape, and condition of an elephant’s tusks can provide insight into its age and overall health. Larger tusks generally indicate an older, healthier elephant, while damaged or discoloured tusks may suggest malnutrition or disease. Scientists study tusks to learn more about elephant lifespans and the impact of environmental changes on their well-being.
10. Conservation Efforts Are Protecting Elephants
Many conservation organisations are working to protect elephants and reduce poaching. Some measures include stricter law enforcement, anti-poaching patrols, and public awareness campaigns against the ivory trade. Protected reserves and sanctuaries also provide safe habitats where elephants can thrive without the constant threat of poaching.
Ethical safaris represent a crucial step towards sustainable wildlife tourism, ensuring future generations can continue to experience the beauty of South Africa’s wildlife heritage while preserving the natural environment for the many wild animals and local communities that depend on it.

Elephant tusks are an incredible adaptation that has helped these majestic creatures survive in the wild for centuries. However, the demand for ivory has placed them in great danger. By spreading awareness and supporting conservation efforts and ethical safaris, we can help ensure that future generations can continue to admire these gentle giants in the wild.
