There are two complete genomes and at least 83 mitochondrial genomes for species in the phylum Mollusca.

----

==== Complete Genomes:====

There are two mollusk genomes publicly available:

  * [[http://en.wikipedia.org/wiki/Aplysia_californica|California sea hare]], //Aplysia californica//
    * Animalia, Mollusca, Gastropoda, Heterobranchia, Opisthobranchia, Aplysiomorpha, Aplysioidea, Aplysiidae, Aplysia
    * This is the most complete mollusk genome assembled.
    * The sequencing and assembly was performed at the [[http://www.broadinstitute.org/|Broad Institute]] in Cambridge, MA. Their project site is [[http://www.broadinstitute.org/science/projects/mammals-models/vertebrates-invertebrates/aplysia/aplysia-genome-sequencing-project]].
    * It was added to the [[http://genome.ucsc.edu/cgi-bin/hgGateway?hgsid=155184841&clade=other&org=Sea+hare&db=0|UCSC Genome Browser]] on March 19, 2010.


  * [[http://genome.jgi-psf.org/Lotgi1/|Giant owl limpet]], //Lottia gigantea//
    * Mollusca, Gastropoda, Prosobranchia, Patellogastropoda, Nacellina, Lottiidae
    * [[http://genome.jgi-psf.org/Lotgi1/Lotgi1.info.html|JGI]] says 359.5Mbases, but the scaffold is still over 20,000 contigs, with the largest scaffold only 9.4Mbases.  It looks like it has been almost 3 years since anyone did anything on //Lottia gigantea.//
    * Tom Pringle sent e-mail to genecats that said, //"There are a great many stalled-out JGI genomes like this. The
last of 5.3 million traces appeared in May 2005. In Jan 2007,
JGI presented the genome at a meeting talk. No paper ever
appeared. A quarter million cDNA were seqd by Dec 2007. JGI
offers blast of the assembly 1.0 and display on their funky
browser. Their gene models are worthless and are not
integrated with the cDNA. SuperFamily has analyzed 23,851
models for domains. Nothing has been submitted to Genbank wgs
division. No explanation appears on their Lottia web page
which has not been updated for several years."//

Of the two genomes, the sea hare seems to be taxonomically closer to //Ariolimax dolichophallus//.

==== Mitochondrial Genomes:====

[[http://www.ncbi.nlm.nih.gov/genomes/genlist.cgi?taxid=6447&name=Mollusca|NCBI List of Mullusca genomes]] - This list shows all Mollusk (taxid: 6447) entries in the NCBI genome database. For some reason this list only shows mitochondrial genomes. Even the sea hare is missing (just lists a older mitochondrial sequence from University of Florida. This could indicate that there are other mollusk genomes out there or in progress.
