Mussel of the Month

The October 2013 Mussel of the Month is Ptychorhynchus pfisteri. Ptychorhynchus is a genus of three species found in China and southeastern Asia.

Ptychorhynchus pfisteri
MNHN. China. (type of U. pfisteri var. insperatus)

It has been a busy week, and weeks like this are when we roll out a Mussel of the Month, like Ptychorhynchus, about which we know absolutely nothing. Less to say, so there is less to write. Google Ptychorhynchus and see what you find: mostly this web site and the suggestion that you might mean "Pachyrhynchus."

Ptychorhynchus pfisteri does have a Red List page. That's something. It is ranked as Near Threatened.

Our classification for this species is a guess. The Russian Comparatory School (e.g., Bogatov et al., 2003) wants to classify this mussel in the Margaritiferidae.
