Question: Trying to find title/author of story I read many years ago, around 1964. Story was written from the point of view of a snail like creature. The central character describes (stream-of-consciousness?) himself and other characters moving along a path in a constant search for food. The story ends with the main character falling into what turns out to be the fuel tank of a space ship.

Answer: 
This is "On the Fourth Planet" (1963) by J. F. Bone. The question was asked before as ["Short story where creatures have squares of territory."](https://scifi.stackexchange.com/questions/36463/short-story-where-creatures-have-squares-of-territory/45888#45888) Originally published in the April 1963 issue of *Galaxy* and [widely anthologized](https://www.isfdb.org/cgi-bin/title.cgi?44472).
You don't give much detail, but it sounds like Dragon's Egg by Robert Forward. From Wikipedia: *Dragon's Egg is a neutron star with a surface gravity 67 billion times that of Earth, and inhabited by cheela, intelligent creatures the size of a sesame seed who live, think and develop a million times faster than humans.*
