What would you do with a trunk if you had one? Would you use it to pick up things? To suck up water? Would Dylan be able to make an even louder trumpeting noise?!
A long trunk is a wonderful adaptation that has developed in elephants over many generations, during the millions of years they've been on earth. Millions of years ago they didn't have the very long trunk that they do now. However, those that had a longer trunk than their peers were able to survive longer and have more babies who also had longer trunks. This process repeated itself generation after generation as the elephant evolved into the animal with the long "nose" we recognize today.
So, how does a trunk help an elephant? It uses it as a suction device to suck up water, and then squirt it into its mouth. It can't drink the water through its trunk, because the trunk is also its nose. I loved watching them do this when we came upon some elephants at a river. Since it's a nose, the elephant can also inhale dirt into its trunk and then blow it out over its head to get rid of bothersome bugs. You'll see an elephant do this in the video.
The elephant also uses the trunk as a hand. It picks up branches to eat, and sometimes even throws them at an enemy! It touches another elephant with its trunk as a sign of friendship.
Here are two very surprising ways I saw the elephant use its long nose. It touches the ground in front of it when walking to make sure it's safe. You'll see this in the video of the mommy elephant and calf (baby elephant) crossing the road. Notice that they keep touching the ground with their trunks. The calf won't go down to the road until he's sure his trunk can touch the ground first.
Secondly, if an elephant hasn't seen a friend in awhile, it will put its trunk into the other's mouth as a friendly gesture. Warning. Don't do this the next time you see your friend. Just give a high five!
The trunk is also used as a signalling device. The elephant raises its trunk and makes a loud trumpeting sound when it wants to call other elephants or scare a predator away. Now, wouldn't it be fun to be able to do THAT?!
Of all the animals we saw on safari, the elephants were the most interesting to watch. They are very intelligent animals that socialize a lot with each other. (Many other kinds of animals hang out together in herds, but don't really socialize with each other.) The best entertainment on the Serengeti is watching baby elephants. They push and tease each other, play together, playfully fight, and also try to imitate the grown-up elephants.
I saw one calf that went off with his friend. He realized he had wandered too far away from his mommy and couldn't find her. He began looking this way and that, running around the many elephants that were standing in the herd. It was easy to see he was worried. Finally he found her! They touched each other tenderly with their trunks, and then he stayed very close to her.
How does a calf recognize its mother? Smell. If you look closely at some of the photos on this page, you see a dark wet stain on the elephant's face, between the eye and the ear. The liquid has a smell that's unique to that animal. People have unique smells too, although usually we try to decrease them by bathing often and using deodorant. Still, I bet if you blindfolded yourself you could recognize your parent by smell alone. Give it a try!
We saw many elephant herds while on safari. They were made up of 10 – 20 female (women) elephants and several calves. The mother and the "aunts" all help raise the calves together. Herds are always led by the oldest, largest female. She will lead the way when going to a new place where there might be danger, and she'll make sure she's last when the herd is running away from danger, always protecting her herd. A group of females typically stay together all their lives – over 50 years!
When we saw an elephant by itself, we knew it was a male (man). The adult males usually live alone, although they may travel with a few other males for a little while, before going their own way again. Similarly, males will come visit the female herds for awhile, but then go off on their own again.
Sometimes male elehants will fight. If you ever see an elephant lifting its head very high, with its ears forward, and quickly unfurling its trunk as it makes a loud trumpeting sound, you've got a big problem. Those are the signals that the elephant is about to charge at you! If you were another big elephant, he would tuck his trunk under (as it's actually quite sensitive) and get ready to hit you with his head and tear you with his two long teeth (tusks).
Here's the good news and bad news about elephants in an ecosystem . The bad news is that they're really hard on their habitat. They're herbivores, so they eat only plants (no meat). But they have really big bodies, so they need A LOT of food. I'm sure you can guess the result. A herd of elephants will eat not only the leaves off the trees, but it will then eat the branches, and THEN it will strip the bark off the trees with its tusks for dessert! If an elephant can't reach the high branches it wants, it'll keep hitting its head on the trunk of the tree until it knocks it over. Needless to say, this kills many trees, and can destroy an entire forest.
Here's the good news. The elephants swallow the seeds of the trees whole. You know what that means – they're still in good shape when they're pooped out the other end. Isn't that fantastic?! That means they're able to grow into trees, beginning their new lives in a wonderful fertilizer – elephant dung. So, although the elephants may destroy a forest, it will eventually grow back into a new forest after the elephants have moved along to a new area.
The dung beetle also thinks it's fantastic. This little decomposer rolls up animal dung into a ball, and then burrows inside. It uses it as a home, AND as breakfast, lunch and dinner!
The very sad news is that some areas still have trouble with poachers. They kill elephants so they can cut off their tusks and sell them for a lot of money. It's illegal, but it can be hard to catch the poachers. It's hard to imagine that anyone would want to harm these magnificent, fascinating animals. The happy news is that there are park rangers, governmental organizations, and other groups (like the World Wildlife Fund) that are working to keep the elephants safe. What do you think? What do you think would happen to this ecosystem if all of the elephants were killed off?
