Arkonians

     The Arkonians are a reptilian humanoid species native to either the Alpha or Beta Quadrant.  They are a warp capable species.

     They do not have sweat glands.  Their hydration system isn't based on water.  Instead, they drink a dark brown liquid.

     The Vulcans made first contact with them some time after the early 2050s.  It was at this time when they achieved warp flight.

     In 2152, Starfleet made first contact with them when the crew of the NX-01 Enterprise met with them.  The two ships would have to work together to find missing crewmembers.
