If you were trying to write "limnic", that would be a valid word. Limnic refers to:
* Of or relating to freshwater lakes and ponds.
* Relating to the limnetic zone (the well-lit surface layer of a lake or pond)
If you were trying to write "limicolous", that would also be a valid word. Limicolous refers to:
* Living or growing in mud or wet ground.
* Specifically used for birds that live and feed in muddy areas, like shorebirds.
It's possible the word you're looking for is one of these, or something else entirely. If you can provide more context, I may be able to help you understand what you're looking for!
