GASTROPODA (slugs and snails) may also be included in identification literature listed under the following higher taxa:

NBNNBN (data.nbn.org.uk) has a distribution map for GASTROPODA (slugs and snails)
BioInfoBioInfo (www.bioinfo.org.uk) has 155 host/parasite/foodplant and/or other relationships for GASTROPODA (slugs and snails)

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)
