Abstract

A small, but significant proportion of the empty tubes of the free-living serpulid Ditrupa arietina dredged from the seabed off São Miguel, Açores, were punctured by small round holes. Analysis of these holes shows that they are typically single, made from the outside of the tube and located preferentially, suggesting that they represent the work of a predator. The likely identity of the predator is discussed but based on the co-occurrence in the dredges and the fact that most of the holes have a distinctive countersunk morphology, it is suggested that they were made by the small naticid Natica prietoi. If so, this study is the first record of such a predator/prey relationship.
