Living or dwelling within or inside a cyst, describing organisms that inhabit cyst-like structures.
From Latin 'cystis' (cyst) + '-colous' (inhabiting/living in). This biological term combines cyst with the Latin suffix for habitat preference.
Some organisms are cysticolous specialists—they've evolved to live only inside cysts, like tiny apartments made by their host! This shows how life finds every possible niche.
