Although echinoderms do not have a circulatory system, they have a hemal system which is thought to help distribute food to various parts of the body. Distribution of other substances (nitrogenous waste, dissolved gasses) may be acheived through currents in the coelomic fluid.

The capabilities to regenerate body parts represent an obvious advantage for echinoderms. Firstly, for the replacement of tissues following predation, an ability that echinoderms show to a greater extent than other invertebrates.

Among deuterostomes, the regenerative potential is maximally expressed in echinoderms, animals that can quickly replace most injured organs. In particular, sea cucumbers are excellent models ... In general, the ability to replace complex body parts decreases as one moves from the basal to the more highly derived taxa.
