Of or relating to geckos; gecko-like in nature or characteristics.
From 'gecko' with the suffix '-ian' (relating to), following the pattern of words like 'reptilian' or 'amphibian' to denote membership in a class or group.
This is a more formal scientific way of saying 'gecko-like,' and it appears in technical literature when scientists want to describe gecko-related traits—it's the kind of word that makes scientific papers sound impressively specific!
