Teredo bartschi
Taxonomic Group: Mollusks-Bivalves


Teredo bartschi is commonly known as the Bartsch Shipworm. Shipworms are highly modified mollusks, adapted for boring into wood. Although it was first described from the southeastern United States with type specimens from Tampa, Florida, it is widespread throughout tropical and subtropical seas, making its native origin difficult to determine. For this reason it is considered cryptogenic throughout most of its global range. Introduced populations are known from Mexico, California and Hawaii. This species has been reported from fixed wood structures, panels, driftwood, and mangroves in tropical and subtropical climates, and in heated power plant effluents in temperate waters. It is one of many shipworms contributing to the rapid riddling of wood in tropical and subtropical waters. Its impacts in these warm waters are difficult to assess; however, in some areas it can cause extensive damage to wooden marine infrastructure.
