Dear Terry,
Success this time. These radula pics are from the animal from Thailand, at the top of the page, which Rebecca Johnson referred to in her message.
Rebecca,
This radula is rather different from the specimens of Thorunna florens that I have looked at. The innermost teeth in my specimens look like the the uppermost tooth in your upper right photo. Is this Tooth2 on the right side?. As you say the innermost teeth in your specimen (lower right) look like the innermost teeth in some other species such as T. daniellae and T. africana. Do all the rows have this structure? I was wondering whether the oldest rows had the T. daniellae-type tooth and the youngest rows the elongate innermost tooth. It certainly is interesting.
Bill Rudman.
