Mammals communicate in various ways to convey messages and emotions. They use vocalizations, such as the howls of wolves or the songs of whales, to express needs or establish territory. Body language, like the tail wagging of dogs or the ear positioning of cats, also plays a crucial role in their interactions. In addition to sounds and movements, some mammals use scents to communicate. For example, rodents may leave scent trails to mark their territory, while elephants can detect pheromones to find mates. These diverse methods help mammals connect with each other and navigate their environments effectively.
