I know this had been asked a lot, but I really want to know, on hoshigaki clan page, it stated that their gills are just facial features? but really are they? shizuma's gills were moving and opening which I dont think facial features can do? I personally think kisame and his clan can breath underwater but i'd want other's opinions/facts
