Dear Bill,
Thank you for your identification.
It is surprising for me that you commented "if it were Spurilla neapolitana it would be an interesting new record."

Last year I found three or four "Spurilla neapolitana?" on the same beach. This year I am going to go that beach again. Recently I bought macro lens for my camera, so I will be able to send you photos in which you can see the shape of the rhinophores if I find "Spurilla neapolitana?" again.

Best regards,
Satoru Hori.

Dear Satoru,
If your animal is a recent introduction to Japan, perhaps from some larvae in ballast water, or from adults on the outside of a ship, then it is fairly usual for there to be an initial population explosion. Is the place where you are finding these animals near a major port with overseas shipping?

Sometimes introductions don't survive past the initial generation, other times they do very well and become pests in their new home.

Good luck with finding and photographing another animal.
Best wishes,
Bill Rudman.
