In The Land Of Starfish, Humans Are Disabled
Ordinary, able-bodied human beings are at a serious disadvantage in a world populated by Starfish Aliens.
You know the old saying, "In the land of the blind, the one-eyed man is king?" Well, according to at least one speculative fiction trope, that might not be true. In the land of the blind, everything is designed for blindness, and sighted people will find themselves at a serious disadvantage just trying to get around when lights don't exist and everything is designed for echolocation. This trope, in short, is about what happens when an ordinary human being finds himself in a land populated by, and thus designed for, creatures that are significantly different from ordinary humans. What's easy for a human is almost impossible for the creatures; what's easy for the creatures, on the other hand, is quite difficult for a human. And thus everything is designed in a way that's perfectly normal for the planet's denizens, but entirely inconvenient for the human visitor. Curiously, although I love this trope, I can't actually recall any specific examples off the top of my head right now. But I know I've seen it.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
