Humans are pretty lucky with the way we can communicate. Unlike animals, we have the perfect length necks and excellent control of our breaths. Both of these characteristics allow us to form words. Although animals can't talk like us, they still have special ways to communicate. For example, dolphins have one of the most sophisticated forms of communication. They make distinct whistling sounds that help identify themselves. Dolphins may also squeak or Yelp depending on the situation. Nevertheless, each sound release meaningful information. You have probably heard some birds say words just like us, but they are merely repeating what they hear. Most birds communicate through songs and squawks that can be beautiful for us to listen to. Other animals communicate without making a sound. Elephants show affection by wrapping their trunks around each other; whales leap out of the water to send messages to their friends; bees perform a special dance when they have located nectar in a tree. Even if it's just our pet dog wagging his tail or a pet cat purring, all animals have their own way to convey information to us and each other.
