In a sense yes. When we urinate we are actually getting rid of nitrogenous waste that is in our blood, by filtering it with our kidneys and excreting it. The starfish, and all other animals, must excrete their nitrogenous waste as well. The starfish filters its blood with its organs, and excretes it through its feet.
