* Fighting: The long neck and head are used as a weapon during fights for dominance and mating rights. They "neck" each other, using their heads and necks to deliver powerful blows.
* Displaying dominance: A giraffe's neck and head are used in displays of dominance, such as head-bobbing and neck-stretching.
* Reaching higher branches: While primarily used for eating leaves, their neck allows them to reach branches that other animals cannot, giving them a competitive advantage.
* Reaching water: In some cases, they use their long necks to reach water sources that are too deep for other animals.
So while their necks are primarily for eating, they're also important tools for social interactions, competition, and resource acquisition.
