Answer 2

Answer:

Without excretory organs, starfish are still able to get rid of their waste, not quite like humans. They are capable of excreting waste from their anus and they release liquid nitrogenous waste, or urine as well. Once a starfish's food is digested it passes from the stomach and passes down through the anus.
