Ear positioning refers to the orientation and placement of the ears on an animal's head. In many species, including dogs and cats, ear positioning can indicate mood or alertness. For example, ears that are perked up may signal curiosity or excitement, while ears that are flattened against the head can indicate fear or submission. In humans, ear positioning is generally fixed, but some individuals may have ears that stick out more than others. This can be influenced by genetics and the structure of the skull. While ear positioning does not typically affect hearing ability, it can play a role in personal aesthetics and self-image.
