Asari

The asari are a bipedal species that have a seat on the Citadel Council. Of all the species in Council space, the asari are the most widespread, powerful, and respected. This is due in part, to their being the first species, after the Protheans, to achieve interstellar flight, (to discover and learn how to use the Citadel) and their position as a founding member species of the Citadel Council.

A typical asari individual has a blue and/or green complexion. In the place of head hair, the asari possess wavy folds of sculpted skin. The asari are the closest species aesthetically to humans. Though asari appearance is typically similar to that of a female by human standards, asari are non-gender specific, meaning they have no concept of gender differences. This is likely due to there being no physical difference to separate different sexes, though this has not been verified. It also has not been revealed whether asari reproduce asexually, without the need for another individual's genetic material, or whether they reproduce with the input of another individual, but are still non-gender specific, meaning that any two individuals could mate with one another to produce offspring.
