      That is a thing, but it’s usually a short lived stage after a metamorphosis to mate or do something, if it’s less than a month the strategy works. Not having an anus and stuff means you can not grow that organ and make something else instead or have a shorter growth period.

      Some microscopic animals don’t have anuses, but that’s because they have one dual purpose orifice that handles food in both directions.
