This article has some strange POV problems.  Several times it unreservedly claims that Rods are only insects, which is rather POV.  Not only that, but it then confusingly goes on to contradict this view by giving descriptions of Rods according to the "skyfish" theory (also POV).  It's not really presenting both theories as opinions on the matter; instead it seems to be presenting *both* of these mutually exclusive theories as fact.
