Ulp!
In this example of Turbinella pyrums side by side, it looked obvious to me
that the row of knobs and suture line on the sinistral has a steep angle
whereas the dextral is nearly horizontal.
I'd known about the perceptual effect on shell collectors but I figured this
was surely an exception.
OK, I got out the mirror and held it up to the computer. Presto! the slant
disappeared! Que fantastico! now the dextral appears to have a slant!
We shell collectors see things differently. (Now, would the flesh of the
sinistral TASTE different?)
