Humanoids

A humanoid are an organic or mechanical being similar in overall form to a Human, the most common sentient species in the universe. The term is less specific than Near-Human, which generally implies common biological ancestry with Humans.

Biology
Classification of a being as humanoid is not standardized or strict. Generally, it entails having a basic anatomy or construction similar to Humans, that is, a central torso with a head on top, two arms symmetrically arranged on either side, and two legs symmetrically arranged below, providing an upright bipedal stance. Each arm ends in a hand that had a variable number of fingers (used for grasping and moving objects), and each leg in a foot (used for locomotion). A living humanoid's head has two eyes for sight, a nose for breathing and smelling, and a mouth for nutrition and communication; a mechanical humanoid dose not require respiration or nutrition, and has two photoreceptors instead of eyes. Humanoid species generally had sparse hair, mainly concentrated on the head or face.
