Tidepool Tim says,  “Sea potatoes are a unique sea squirt or tunicate in that they grow on a long stalk that is typically 3-4 times the size of the squirt itself.  We find very tiny potatoes in some of our tidepools in very high current areas. Sometimes we will get them anchored in a kelp holdfast community.  Speaking of communities, the sea potato's stalk serves as a place for other invertebrates to anchor themselves, feed on, or just cling to during the ebbing and flowing tides.  We have found them literally covered in a fuzz of skeleton shrimp, sea lettuce, crabs, brittlestars, borer clams, and some bryozoans attached to them. Fishing boats tear large clumps of these from the sea-floor as they dredge for scallops and sea urchins in our bay.  Sometimes these big clusters will wash up on the beaches here. Like any tunicate - this animal filters plankton from the seawater and strains out food particles passing them on to their primitive stomach and gut. As far as i know these have no commercial importance to humans as of yet.”
