Tridacna ‘maxea’: New giant clam hybrid of Tridacna maxima x T. crocea

It’s not everyday that we get a new giant clam species but this week’s coral shipment to the LFS included a special sumthin for the clam lovers. Although T. derasa and T. squamosa hybrids have been around for years, the T. maxima x crocea (T. ‘maxea‘) hybrids have just recently become available from captive hybridization on the farm. The Maxea clams have a really unique appearance with blue and gold markings that lead us to believe that the hybrids are produced by a cross of gold and blue varieties of the two parent species. Not all Maxeas are created equal and there appears to be great variability in the appearance and vibrance of this new hybrid clam variety.  The Maxeas are not too expensive, where a 2-3″ high grade T. maxima would sell at retail for $79, a similarly sized Maxea would probably retail for $99-$119.

    There are VERY few publications describing genomic analysis of Tradachnid clams. I dont know that there is enough sequence data out there to define the two species based on DNA sequence polymorphism. I am a molecular geneticist at Harvard University. If anyone can provide me with suitable biomarkers and tissue from t maxima t crocea and the proposed hybrid, i would be happy to do the PCR and sequence the regions myself and provide you with an answer. if you have this info and samples, please post your contact info on this board.

    Some of you think you are the last source for all info, if you dont know it, its not possible metality. This is the same as all the new montis and chalices coming out lately. think about it…
