Abstract

In February 2011, after a storm, thousands of adult, articulated, and still-living common otter shells Lutraria lutraria (L. 1758) were stranded on the North Sea beach of the Island Texel (NL). These 9 to12cm long bivalves were rapidly found and consumed by both herring- and lesser black-backed gulls. Holes, irregular in outline, were observed in some 10% of the articulated shells of these bivalves. These holes were always smaller on the outside of the valves than on the inside and varied in size from 1 to 20mm (outside) to 4 to 22mm (inside). Often the other valve was crushed indicating consumption by gulls. We concluded that these holes were made by the gulls probing the shells; in a few cases, we observed that valves were broken starting from such a hole. Such traces are described in the literature as the ichnogenus Belichnus and were until now attributed to Stomatopoda only. We also suggest that a separate ichnospecies name for two Belichnus holes in one shell should not be used, as we see them simply as a double injury due to two blows. Our findings stress once more the importance of avoiding premature phylogenetic interpretation of traces and the use of a separate ichnotaxonomy.
