GASTROPODA Cuvier, 1795 (slugs and snails)

Further Information

Lab. techniques To prepare microscope slides of the radula:

1. Gently cut off or extract the head region of the dead snail.
2. Macerate in 5% KOH in a hot waterbath until the tissues disintegrate, (about 10 mins for a small snail)
3. Find the radula (not always easy! Even adding Safranin to the alkali doesn't help)
4. Stain in Safranin
5. Wash
6. Make a temporary mount in lactophenol (but this tends to dissolve out the stain: need to experiment with other stains eg Lignin Pink)
