The salarians are a warm-blooded amphibious species from the Milky Way planet of Sur'Kesh. Naturally fast metabolisms mean that salarians live intense but short lives of less than forty years. Their quick intellect and photographic memory make them gifted scientists and engineers, and the Salarian Union is renowned for its technological advances as well as its secrecy and intelligence-gathering.
Tension between salarians and the krogan has lingered for centuries. Salarian scientists were responsible for creating the genophage that devastated the krogan population and ended the Krogan Rebellions.
Almost 90 per cent of the salarian species is male. Political power is centered in "Dalatrasses," rare salarian females who negotiate the fertilization of eggs and the strategic alliances that result. Many salarian females chose to join the Andromeda Initiative as civilians, a significant break in salarian tradition.
