Contribution a l'étude des xylophages marins

These first results might clarify some problems linked to the biology of tarets and other small lignivorous crustaceans. The systematic of the molluscs Teredinidae, so complex, is only based on the study of pallets, which is a great source of confusion when one has to examine the woods after the molluscs' death. We tried to distinguish the species by examining the striates and denticulations on the shelves. The size of the intervals between the striates and the proportional size of the denticulations, as well as the shape of the denticulation marks of the middle part, can indeed allow us to differentiate between some species.
