It has always been my understanding through a number of different things I have read in the past, that the Annunaki are comprised of a number of different species, not one in particular. Based on those readings, I came away with the feeling that "Annunaki" was simply a name for the group or organization of multiple beings/species. Obviously this is only speculation on my part and the multiple readings that I have done could be completely false. It might also be noteworthy to mention that I also came away with the feeling that the Annunaki are comprised of Fallen Beings, or in other words negative entities, service to self beings, etc. Again, take it with a grain of salt because as we all know too well, nothing has been proven yet.
