According to the scientific definition of a species (as is currently
understood) two different species are not supposed to be able to reproduce
fertile offspring.  However, two seperate species are able to reproduce
sterile offspring.  Ex.  a mule is a hybrid of a horse and a donkey.   Two
mules cannot produce a mule.  They cannot reproduce at all.  They are sterile.
The only way to produce a mule is to mate a horse and a donkey.  The same
applies to hybrids in Cypraeidae or any other mollusk.  They may produce
offspring which is sterile, but by definition hybrids themselves cannot
reproduce.
