Reproductive type (?) | Sexual References: Cragg, S. M., Jumel, M. C., Al-Horani, F. A., Hendy, I. W. 2009. The life history characteristics of the wood-boring bivalve Teredo bartschi are suited to the elevated salinity, oligotrophic circulation in the Gulf of Aqaba, Red Sea. Journal of Experimental Marine Biology and Ecology, 375(1-2), pp. 99-105. Comments: Shipworms are protandrous hermaphrodites, beginning life as male and transforming to female. |
Developmental trait (?) | Spawning References: Cragg, S. M., Jumel, M. C., Al-Horani, F. A., Hendy, I. W. 2009. The life history characteristics of the wood-boring bivalve Teredo bartschi are suited to the elevated salinity, oligotrophic circulation in the Gulf of Aqaba, Red Sea. Journal of Experimental Marine Biology and Ecology, 375(1-2), pp. 99-105. Comments: Males release sperm into the water column which fertilizes eggs for the female. The fertilized eggs are then brooded in the gills. |
Characteristic feeding method / Life stage (?) |
References (not structured): Cragg, S. M., Jumel, M. C., Al-Horani, F. A., Hendy, I. W. 2009. The life history characteristics of the wood-boring bivalve Teredo bartschi are suited to the elevated salinity, oligotrophic circulation in the Gulf of Aqaba, Red Sea. Journal of Experimental Marine Biology and Ecology, 375(1-2), pp. 99-105. Comments: Oligotrophic waters at Aqaba limit the food available for planktotrophic larvae, but brooded larvae may get their nutrition by matrotrophy, a form of feeding that could be driven by parental intake of wood rather than phytoplankton. Furthermore, pediveligers of T. bartschi, like those of L. pedicellatus, may not require phytoplankton as food before metamorphosis. Adults can survive in oligotrophic conditions as they benefit from the nitrogen fixation capability of their bacterial symbiont. |
Mobility / Life stage (?) |

Journal of Experimental Marine Biology and Ecology, 375(1-2), pp. 99-105. Comments: Shipworms are highly modified mollusks adapted for boring into wood. |

Habitat modifying ability potential (?) | Allogenic ecosystem engineers References: Cragg, S. M., Jumel, M. C., Al-Horani, F. A., Hendy, I. W. 2009. The life history characteristics of the wood-boring bivalve Teredo bartschi are suited to the elevated salinity, oligotrophic circulation in the Gulf of Aqaba, Red Sea. Journal of Experimental Marine Biology and Ecology, 375(1-2), pp. 99-105. Comments: Shipworms are unusual varieties of marine clam that have evolved to bore into and eat wood in the marine environment. They settle onto wood as tiny larvae and grow longer as they bore inside. They digest the wood using symbiotic bacteria, rather like termites do. Shipworms leave little outside trace of their activities but small entrance holes. |
