Someone could compile an encyclopedia just about all the fictitious Martian races, maybe starting with the major writers -
British: Wells, Stapledon, Lewis;
American: Burroughs, Heinlein, Bradbury;
also: Blish, Anderson, Niven, Weinbaum;
ERB-related: Arnold, Kline, Moorcock;
screen: Quatermass and the Pit, Doctor Who's Ice Warriors, Mars Attacks!;
comics: DC Comics' Martian Manhunter.
And many others. Some of these writers have more than one version of Mars and its inhabitants and some of the Martians exist only in the imaginations or speculations of the fictitious characters.
Here is a question for Anderson fans: how many Martian races does Anderson have? (And should we include extra-solar colonists of Mars who come to be called "Martians"?)
Fictitious Martians are either serious scientific speculation about hypothetical Martian life or exercises in imagination about possible other life forms. Anderson's Shield contains both. He mentions something like gnarled trees with long branches, an idea about conceivable Martian vegetation. But the Martians themselves have a different language for each sense, vocal, tactile etc. Further, each language articulates a different aspect of experience so that they are not mutually translatable but between them build up a completer view. Here, Anderson has gone beyond talking about Mars and is instead speculating about alternative modes of consciousness.
