Elephants are amazing animals with special body parts that help them live and thrive in their environment. Let’s explore some of these fascinating features!
One of the most noticeable parts of an elephant is its trunk. This long, flexible part is actually a modified nose! Elephants use their trunks for many things: smelling, breathing, and picking up food and water. It’s like having a super handy tool right on their face!
Elephants have long, strong tusks, which are actually special teeth. They use these tusks to dig for food, gather things, and protect themselves from danger. In elephant families, tusks can also show who’s the boss, especially among the males.
Elephants have very large ears that help them hear sounds from far away. Their big ears also help them stay cool. When elephants flap their ears, it helps to lower their body temperature. Plus, they use their ears to communicate with each other by moving them in different ways to show how they feel.
Have you noticed how elephants have wrinkly skin? Those wrinkles help them keep water in their skin, which is super important in hot places. This helps them stay cool and not get too thirsty.
An elephant’s tail has a hairy tip that acts like a fly swatter. They use it to shoo away pesky insects and other little creatures that might bother them.
Elephants have strong legs and wide feet that help them walk through different types of land. Even though they are big, elephants can walk long distances to find food and water. Their powerful legs also help them run away from danger or scare off threats if needed.
Underneath their feet, elephants have sensitive pads that can feel vibrations in the ground. This helps them communicate and stay aware of what’s happening around them.
All these amazing body parts work together to help elephants survive, grow, and live their daily lives. Aren’t elephants incredible?
Trunk Exploration: Try using your own “trunk”! Find a long sock or a piece of cloth and pretend it’s an elephant’s trunk. Use it to pick up small objects like toys or pencils. How many different things can you do with your “trunk”? Think about how elephants use their trunks in the wild and discuss with a friend or family member how it might feel to have such a useful tool.
Ear Flapping Experiment: On a warm day, go outside and try flapping your arms like elephant ears. Do you feel cooler when you flap them? Discuss why elephants might need to cool down and how their big ears help them. You can also make paper elephant ears and attach them to a headband to see how it feels to have big ears like an elephant!
Wrinkly Skin Observation: Take a sponge and soak it in water. Notice how it holds the water. Now, let it dry and see how it wrinkles. Compare this to an elephant’s skin. Discuss with a partner why having wrinkly skin might be helpful for elephants in hot environments. Can you think of other animals or things that use wrinkles to hold water?

Elephants have external structures that help them survive and obtain the resources they need to grow and reproduce.
Let’s look at some of these external structures. Elephants are well known for their impressive trunks, which are actually modified noses. They use their trunks to smell, breathe, and gather food and water.
Their tusks are modified teeth used for digging, gathering food, and protection against predators. In the social life of elephants, tusks can indicate hierarchy, especially among males.
Elephants also have large ears that aid in hearing, allowing them to pick up sounds from far away. The size of their ears provides a large surface area with blood vessels close to the surface, which helps regulate their body temperature. By flapping their ears, they can cool themselves down.
Additionally, elephants use their ears for communication, with different ear positions conveying their feelings. Their wrinkly skin helps trap moisture in the cracks, reducing water loss and keeping them cool in hot and dry environments.
Elephants have tails with hairy tips that they use to swish away insects and other small biting animals. Their sturdy legs and broad feet enable them to move through varied habitats. Despite their size, elephants can walk long distances in search of food and water, demonstrating remarkable endurance. When faced with a threat, their powerful legs can quickly carry them to safety, either by moving away or charging to intimidate the threat.
Sensitive pads on their feet can detect ground vibrations, providing another means of communication and awareness of their environment. All of these external structures work together with their internal structures to help elephants meet their needs for survival, growth, and daily life processes.
