So I mentioned a certain short story I read years ago on /r/Showerthoughts and a lot of people want me to find it for them, but I have no idea who wrote it. When I was a kid I read tons of sci-fi anthologies, so I'm not sure about the author. It could be someone well known, like Aldiss or Clarke or Wyndham, but most likely it was someone a little less known.
Here's what I remember:
The story was really simple and short - people were finding dead fish (or maybe some other aquatic creatures) dead relatively far from the lake where they lived (in a forest, I think). It was always young strong male specimens, and they found some simple "suits" made of weed or something which they figured were something akin to a spaceship for them. That was the whole point - these aquatic creature were sending explorers on land the same way we send astronauts.
What I can't remember perfectly:
I think the story takes place on Earth, but it could have been an alien planet. I'm not sure. The whole story may be presented as a dialogue of two characters. I'm 95% sure it was just a short story, not a part of a larger narrative. If it was a part of a novel, I'd remember it, as I haven't read nearly as many novels as I did short story anthologies.
So, if any of that rings any bells, I would be grateful if you could point me in the right direction.
From later in the comments:
One more thing - I'm fairly certain it was not a new book when I read it, so it has to have been written in the 90's at the latest, but most likely 80's or earlier.... Definitely a book, and it was translated into Czech. No idea what the original language could have been.
Does this ring any bells for anybody?
