Lyrodus pedicellatus
Taxonomic Group: Mollusks-Bivalves


Lyrodus pedicellatus is commonly known as the Blacktip Shipworm. Shipworms are marine clams which are highly modified for boring into wood. It was first described from Spain, but because it is widespread throughout tropical and warm-temperate waters its native region is difficult to determine. We consider it to be cryptogenic (i.e. invasion status unknown) throughout much of its distribution, but introduced populations are known from the West Coast of North America, Hawaii, New Zealand, and South Africa. It bores into fixed wooden structures, panels, driftwood and mangroves. In some cases it can cause negative impacts to wooden marine infrastructure.
