Invasion
Invasion Description
1st Record: Beaufort/NC/Atlantic Ocean (1893, Sigerfoos 1907) 'Two kinds of worms are found there in great and about equal abundance--Teredo norvegica and Xylotrya fimbriata (actually Bankia gouldi) whose mode of spawning has been already described. A very small proportion of specimens were of Teredo navalis, one of the common European forms, in which the eggs are retained in the gills of the mother during a considerable period of their development, perhaps almost 'till time for them to set into the wood.' (Sigerfoos 1907).

In shipworm surveys in 1922-24 and 1940s-1959, extensive damage to wooden test panels was found from North Carolina to central Florida. However, in this region, T. navalis was joined by several other species, including Bankia gouldi, T. bartschi and Lyrodus pedicellatus, so the extent of its impacts are difficult to determine (Brown 1953; Wallour 1960). | ||
