They tend to be shorter than humans and their ears are very sensitive. Culturally, they are a race of traders and value profit above all else. Additionally, their society is extremely patriarchal and misogynistic - women are not allowed to travel, earn profit, or even wear clothes.

Because they are more concerned with commerce than conquest, they tend to remain neutral in galactic politics. While individual Ferengi have engaged in hostilities with members of the Federation, their government does not condone these actions and the Ferengi have never been at war with anyone else.
