The Manus appear similar to humans, but with noticeable differences. For starters, the Manus have longer ears and noses than their human counterparts. As well, they are naturally shorter, with an average male height of 1.32 meters (4 feet and 4 inches) and an average female height of 1.21 meters (4 feet). They also tend to be less muscular, with the average male weight of 41 kilograms (90.4 lbs) and the average female weight of 37 kilograms (81.6 lbs). What they lack in build, however, they make up for in cunning and intelligence. The Manus' cranial cavity is 150% the size of a human's, allowing them to advance academically and technologically much faster than most other species.
