Invasion
Invasion Description
1st record: Sea dikes/Netherlands/North Sea (1730, Reise et al. 1999, Wolff 2005). Historical accounts of shipworms before 1700 refer to damage to vessels, possibly due to other species (Wolff 2005). Fossil shipworms from northern Europe appear to be those of other species (Moll 1914, cited by Wolff 2005).

| Teredo navalis and other shipworms have long posed a threat to wooden boats, ships, and structures in northern European waters (Hoppe 2002; Wolff 2005; Did?iulis 2011). | ||

| Safety, Shoreline Protection- Teredo navalis was first described in 1731, when it caused massive damage to wooden dikes in the Netherlands, destroying 50 km of seawall, resulting in disastrous floods (Hoppe 2002; Wolff 2005; Didžiulis 2011). | ||
