Their lower legs are bowed backwards significantly, compared to asari or humans. Quarians appear physically similar to humans save for several key features the first being their hands and feet. They have three thick fingers on both hands which include a thumb, an index finger, and a long finger, similar to the middle fingers for humans, as well as three toes on each foot.
