Hello Rick, Franck and Andrew,
I have a growing interest on hybrids.
It is of my experience, that despite finding hybrids is indeed highly
improbable , assuming they are not a real possibility between all related
species is unwise.
The genus Harpa as such a similar morphology, that if hybrids did occur
they could be impossible to identify.
Even experienced collectors, re-read descriptions, before making a final
judgement on the classification of most species within Harpa. If we were
faced with an hybrid, how sure would we be of having found one? A tricky
mutation could easily explain it...
Theoretically, we could interbreed with chimpanzees, and there is at least
one specimen known to exhibit mixed characters. A quantity of different
molluscs with an higher degree of resemblance are interacting continuously
in their underwater routine. What would be extremely difficult, was that
they would not reproduce successfully.
I am sure they come along like sinistralīs, as I keep looking for new ones
to the collection ;)
Best regards,
David C.
