However, interest in this neglected mollusc is likely to be rekindled this month with the publication of a novel by author Julia Stuart set in the pearl fishing communities.
The generalized mollusc is bilaterally symmetrical and has a single, "limpet-like" shell on top.
For example, it is uncertain whether the ancestral mollusc was metameric (composed of repeating units)—if it was, that would suggest an origin from an annelid-like worm.
Two cercariae of each infected mollusc were sexed and genotyped using W1 marker [35] and 12 microsatellite markers, R95529, SmD57, SCMSMOXII, SmD89, SMIMP25[36], SmC1, SmDO11 [37], SmBR8, SmBR13, SmBR14, SmBR16 [38], SMS7 [39].
Two cercariae of each infected mollusc were sexed and genotyped using W1 marker, a female specific sequence only present on the W chromosome [35] and 10 microsatellite markers, R95529, Smd57, SmD28, L46951 [36], SmC1, SmDO11[37], SmBr8, SmBr13, SmBr14, SMBr16 [38].
The Pacific oyster Crassostrea gigas, a widely cultivated marine bivalve mollusc, is becoming a genetically and genomically enabled model for highly fecund marine metazoans with complex life-histories.
The molluscs are aggressive if provoked and their poison-loaded harpoons can penetrate wetsuits.
The molluscs are the first non-insects found to use such farming methods, reports this week's Proceedings of the National Academy of Sciences USA.
These elegant micro-molluscs are a vital food for some fish.
Many critters, especially reef-forming corals and free-swimming molluscs (and most molluscs are free-swimming as larvae), prefer aragonite for their shells and skeletons.
