The
latest additions and changes.
Additions and changes on the present site:
- The page on "Limpets
(Patellidae)" has been freshly

transferred to a new location. (17.12.07)
- The page on "Terrestrial
Snails" has been completely revised! (26.06.07)

Gastropod Shell" has been completely revised! A new
second page has
been added, many further topics on gastropod shells are discussed. (05.05.07)
- My specially
qualified stunt snail Lucy (a Helix lucorum) has now been consulted for a
remake of the famous knife blade experiment. Which is why the page "A
Snail at a Knife's Edge" has now been
revised! Any other pages on that experiment have also been
moved to the new location! (24.04.07)

Chambered Nautilus" has been revised! A new page on the "Fossil
History of the Nautilus" has also been added. (22.04.07)

-
The page "The
scalariform shell" has been moved and revised! (26.09.06)
- A page has been revised: "Pond
snails (Lymnaeidae)". Pond snails are probably among the best known
and also among the largest fresh water snails in Europe, living in lakes and
ponds, as their name says, but also in many aquarium tanks and garden ponds. (04.09.06)
- A page has been revised: "Song
Thrush and Banded Snail". The explanation of the extraordinary variability
of banded snails is polymorphism due to selection by animals hunting snails on
sight, such as song thrushes. (14.08.06)
- A new page has been added: "Slugs
and the Variety of Food Sources". Slugs are well known for
destroying lettuce. But that is not all they eat... (10.06.06)
- A new page has been added: "Merdigera
obscura - the Camouflage Snail". This smaller
relative of the mountain Bulin (Ena montana) hides its shell under a
camouflage of excrement and earth, so that on first sight it is hardly
recognisable as a snail. (08.06.06)
- A new page has been added: "The
scalariform shell". Apart from shell damages by natural
causes there may also be shell deformities in snails, that need not
necessarily be harmful to the snail, among those, for example,
the so-called scalarid or scalariform shell form. (22.05.06).
Note:
