Abstract | During early April of this year, the African barnacle Solidobalanus falax was found on the French Atlantic coast. The species was abundant on lobsterpots in the harbour of Piriac. Two specimens were also found on the beach of Piriac: an empty one on a valve of Spisula solida and a live one was growing on a specimen of the red algue Calliblepharis ciliata washed ashore. In addition, the species was also found on parts of a lobsterpot washed ashore in the neigbourhood of the isle of Noirmoutier. Earlier, the same species was also present on floating objects washed up on the Belgian coast (November 26th 1996 and the 3th and 8th of March 1997). Judging from the accompanying fauna, the objects were clearly of a southerly origin. As all these specimens were empty, an exact determination was at first difficult. It was not until the finding of the fresh French specimens and with the help of the article bij Southward (1995) that an exact determination was possible. Southward describes the first findings of Solidobalanus falax off the Plymouth coast. It seems that Solidobalanus falax, at least along part of the french Atlantic coast bas established itself very well. Although the species may have been overlooked, maybe Solidobalanus falax is yet a fairly recent immigrant in this region. Far instance, the species has never been reparted befare an floating objects with a southerly origin, along the Belgian coast. Further, the author gives more details on the findings and deals with problems concerning the occurrence of a 'new' species. |
