I'm interested in creating a character with a race released as part of Starfinder Society. In this particular case, the Morlamaw. There is at least one other race as well (there may be more, but I haven't played everything yet), the Copaxi. There are a number of other races allowed, but they are sourced in other books, including the adventure paths. Here is a link to the basic races page on Archives of Nethys.
