It's less than obvious from this post's subject line, but I
can still type. Gw'oth (singular, Gw'o) are starfish-like aliens that figure in the
Fleet of Worlds series of novels. Jotoki (singular, Jotok) are starfish-like aliens that figure in the
Man-Kzin War series of books.
The
FOW novels are my space-operatic collaborations with Larry Niven. The
MKW books are short-fiction space-operatic collections "created by Larry Niven," with most stories contributed by other authors. Both series share a setting Larry calls Known Space.
But that's a
very spacious (pun unavoidable) setting: call it a thousand years of future history in a steadily growing volume that is many light-years across. Plenty of room therein for storytelling ...
MKW and
FOW do not meet.
Humanoid aliens teem in SF, with seldom any speculation that the species are related even when the humanoids share a fictional universe. No such forbearance for starfishoid aliens. Speculation abounds, as in this
Wikipedia article about Known Space, that Gw'oth and Jotoki are related.
They're not.
