Subject	Venus verrucosa; Sipunculoidea, Gastrochaenia dubia, Bizerte Lagoon, Tunisia

Description	From August 2003 to July 2004, specimens of the bivalve Venus verrucosa (L.) were collected monthly in the channel connecting the lagoon of Bizerte (Tunisia) to the Mediterranean Sea. During the winter, 4% of the specimens had tiny perforations on the outer and inner faces of the valves; the perforations were connected to an intra-valve network of galleries, caused by 10-12 mm Sipunculoidea. Of specimens collected in February-March, 4% were infested with the lithophagous bivalve, Gastrochaena dubia, that lived within a cavity in the V. verrucosa valves. The cavity communicated to the outside through a calcareous tube developed by the G. dubia near the exit of the V. verrucosa siphons, ndicating parasitism that can cause progressive perforation of the valve and lead to the death of the host.
