The shape of the tentacles is generally adapted to the diet, and to the size of the particles to be ingested: the filter-feeding species mostly have complex arborescent tentacles, intended to maximize the surface area available for filtering, while the species feeding on the substratum will more often need digitate tentacles to sort out the nutritional material; the detritivore species living on fine sand or mud more often need shorter "peltate" tentacles, shaped like shovels. The podia on the dorsal surface generally have no locomotive role, and are transformed into papillae. , Even in those sea cucumbers that lack regular tube feet, those that are immediately around the mouth are always present.
