Resumo: | The colonization pattern of wooden panels by teredinid larvae released from a previously infested focus was investigated. Panels were placed at different distances (1, 10, 20m) and in different directions from the focus. The colonization experiment took place at Parcel do Aleijado, Ilha Grande Bay, RJ. The focus remained immersed in nearly surface water, by the coast, during three months for infestation by teredinids. After this period, it was transferred to the study site. The infested focus and colonization panels remained in water, 10m deep, for three months more. Total density and density of the dominant species were considered for each group of panels. Five teredinid species were found: Bankia fimbriatula, Bankia gouldi, Lyrodus floridanus, Lyrodus massa and Teredo furcifera. The dominant species was Teredo furcifera (76.6%). Significant differences were only observed between directions for total teredinids and for dominant species density. Results concerning the dominant species Teredo furcifera were even more expressive and suggested the occurrence of a local water circulation pattern.
