Radula of Siphopteron quadrispinosum from Koumac

January 16, 2004
From: Bill Rudman

To accompany my report Siphopteron quadrispinosum from Koumac, New Caledonia, here are some scanning electron micrographs of the radula.
The radular formula is 17 x

• Upper right: whole radula. Scale = 100 microns.
• Lower left: section of left half showing outer lateral teeth. Scale = 20 microns.
• Lower right: section showing innermost lateral teeth with two prominent denticles on the cutting edge. Scale = 50 microns.

The two large denticles on the cutting edge of the innermost lateral teeth are characteristic of S. quadrispinosum.

Best wishes,
Bill Rudman

Here is a further electron micrograph showing a section of the right side of radular showing large innermost lateral teeth and smaller outer teeth. Scale = 50 microns.
