    In vivo and in vitro experiments demonstrate that the intestinal caecum of the echinoid Echinocardium cordatum and the rectum of the holothuroid Holothuria tubulosa actively excrete chlorophenol red (CPR) from the individual body cavity towards the gut lumen, a function already demonstrated for the rectal caeca of asteroids. Physiological and ultrastructural investigations of the enterocytes of these organs show that they are functionally and structurally analogous to the cells of the proximal tubules of the vertebrate kidney. The results allow to suggest that the capability to eliminate unwanted substances through the posteriormost part of the gut is a generalized feature within the Echinodermata.
