Radula of Aeolidia helicochorda

From: Bill Rudman


Hare are some SEM photos of the radula of Aeolidia helicochorda. AM C118699. Pilot Beach, Laurieton, New South Wales, Australia. 18mm long alive. Upper photo showing two new teeth, Lower photo showing three of the oldest teeth. Scale bar = 10 microns. Photos: G. Avern.

The radular morphology, consisting of a single broad multidenticulate tooth in each row is typical of the family Aeolidiidae. Another characteristic is how each new tooth is significantly broader than the one preceeding it, so that the youngest tooth can be more than 5 times the width of the oldest tooth.
Best wishes,
