Zirfaea pilsbryi (Rough piddock)
Copyright © 2008
Mary Jo Adams
The shell of the rough piddock is divided into two sections with the lower portion having a rasping surface that is used to burrow into clay, firm mud, shale, and sandstone. The shell can be up to 6 in. (15 cm.) long with the siphon extending to 12 inches (30 cm.) in length and having a diameter of up to 2 inches (5 cm.). This species inhabits the low intertidal zone to a depth of 400 ft. (125 m.).
The rough piddock is also known under the scientific name Zirfaea gabbi and the genus name is sometimes listed as Zirphaea which is not a correct spelling. Other common names for it include right piddock, boring clam, Pilsbry’s piddock, and Pacific rough piddock.
