Family | Teredinidae | |
Order | Myida | |
Class | Bivalvia | |
Phylum | Mollusca | |
Synonym (?) | ||
Sub-species level (?) | Not entered |
Native origin (?) | Not entered Comments: N Pacific Australasia and North Atlantic |
Life form / Life stage (?) |
Comments: Teredo navalis, the naval shipworm, is a species of saltwater clam. |
Sociability / Life stage (?) | Not entered |
Reproductive frequency (?) | Iteroparous References (not structured): Grave B H (1928) Natural history of shipworm, Teredo navalis, at Woods Hole, Massachusetts. Biological Bulletin, Volume 55:4 Comments: Up to 5 million larvae are developed per cycle. The larval phase is 11–35 days, usually 28 day. Larvae disperse with water current. |
Reproductive type (?) | Asexual Self-fertilization References: Grave B H (1928) Natural history of shipworm, Teredo navalis, at Woods Hole, Massachusetts. Biological Bulletin, Volume 55:4 Comments: It is a protandric hermaphrodite. During metamorphosis male gametes develop after six weeks. They can also self-fertilise. After reproduction it changes back to the male phase and another cycle is started. Fertilisation is internal and female carries the young embryos in the gill chamber |
Developmental trait (?) | Not entered |
Characteristic feeding method / Life stage (?) |
References (not structured): Grave B H (1928) Natural history of shipworm, Teredo navalis, at Woods Hole, Massachusetts. Biological Bulletin, Volume 55:4 Comments: Planktonic larvae are consumed by filter feeders. Adults are only vulnerable to predators once the wood they colonise collapses. |
Mobility / Life stage (?) |
References (not structured): Grave B H (1928) Natural history of shipworm, Teredo navalis, at Woods Hole, Massachusetts. Biological Bulletin, Volume 55:4 Comments: Shipworm burrows in an exposed timber occur within two or three feet of the mud line as a mean of protection. |
Salinity tolerance range (?) | Venice system: 5. α-Mesohaline [10-18psu] 6. Polymixohaline [18-30psu] 7.
