Several morphological characteristics (adaptative or not) could be associated with the process of adaptation to a specific environment or microhabitat. For example, several troglobization processes (species with all the live cycle exclusively in caves) in non-related lineages are associated with the same morphological changes, such as anophtalmy, loss of pigmentation, appendage elongation, etc.
My question is: do there exist morphological changes (and which ones) in arthropods associated with the adaptation to live in a canopy? (and a bibliographic reference if possible).
Thank you very much!
