Bullia rhodostoma is commonly known as the Smooth Plough Shell. It is a sand-dwelling whelk which is native to South Africa. A single dead specimen was found in San Francisco Bay, California in 1966, but no other occurrences are known. In its native range, it is known to use its large flat foot to ‘surf’ up and down beaches and crawl on the sand using a ‘rowing’ motion.
