The elephant’s trunk is a long nose with a strong sense of smell. It is also an upper lip used for drinking and eating. To drink, elephants suck the water up onto their trunk and blow it into their mouths. They eat by pulling up grass or leaves with their trunks and putting the food into their mouths. Because of the muscles at the end, the elephant’s truck is also like a hand that can pick up and carry things. With its flexibility, elephants can use their trucks for all kinds of things, including scratching themselves and throwing things. Furthermore, the trunk plays a part in elephants’ interactions with each other. Elephants can use it to make a wide variety of sounds in order to communicate happiness, anger, or danger. They also use their trucks to touch each other and to show affection.
