Caseolus compactus Endemic like the white bread one. I´ll have some tanks on Christmas available for some species of snails. From the National Institut of Malacology here,they told me that are interested in having an oficial participation on my project. They said that it lacks here a lot of research about land snails, because they study a lot, the marine species but not the land molluscs. So, maybe I´ll give a little help. Hei, I didn´t mean to, but what can I do now? lol.

Unfortunately I only found these pictures on the web, but I hope to have a chance to see how they look like when I´ll go to Madeira island. Some books on Malacology institut has also some pictures. But by now this is what I only have.

Oceanic archipelagoes provide an excellent framework to study the evolutionary forces that drive diversification and speciation. Because of the wide range of geological ages which is often associated with volcanic island archipelagoes, they have always been of special interest to evolutionary biologists. The Azores islands are of relatively recent origin and comprise nine (mostly) volcanic islands near the Midatlantic Ridge with ages varying between 40.000 and eight million years. Recurrent volcanic activity has destroyed large parts of some islands or caused different islands to collide in relatively recent times. Colonization history, range expansion/contraction and secondary contact (hybridization) between populations after eruptive phases or after the fusion of independently colonized islands have important implications for the genetic structure of populations and species.
Most of the autochthonous fauna on these archipelagoes consists of invertebrates and endemicity is particularly high within terrestrial gastropods. Animals with low dispersal capacities, such as land snails, are very useful in elucidating biogeographic relationships.
The Leptaxinae are a subfamily of pulmonate, helicid land snails endemic for Macaronesia (Azores, Madeira, Canary and Cape Verde Islands). The systematics of this group is incomplete, highly confused and almost solely based on shell morphology.
Since the arrival of men on the Azores in 1492, the endemic Laurel-Juniper shrub forest (Laurisilva) was reduced to less then 2% of the islands' surface, being replaced by pastures and plantations. Only on the less accessible parts of the islands, such as mountain ridges and caldeiras, the original vegetation is more or less maintained. Introduced exotics plant species are a major threath for these remnants of Laurisilva but, nevertheless, some of these exotic plants seem to provide a good (micro-) ecological environment for some endemic animals such as land snail species.

Yes, thank you. This specie had a big mortality on 2005 due to extremely dry conditions. The man who found this 3 specimens in Algarve is an engineer that works to the National Institut of Malacology here,and he told me that it´s the first time that he see so few....

The G. turriplana have been eating cucumber and meat. I also put some pieces of calcium on the substrat. They are nocturnal and usually hide inside the moss.

Rumina decolata put loads of eggs! I´m wondering how so many eggs fit inside their bodies... That´s nature, or they might lay eggs in groups ( like 2 or 3 adults) on the same place The Arion sp. slugs are quite big now, around 4 cm. I´ll release some ( 80% of the batch) on the next days on places on which they are known to occur. The same for a Parmacella batch that I have here, they already are growing fast, and I´ll release most of them, on places that suit best for them. I´m keeping also Otala lactea, just gorgeous snails to keep! The Gittenbergeria are quite awsome and pretty snails, but they are fine, until now. They are included on the UE red book af endangered species, so it´s great for me to keep such special specie, when they lay eggs ( if they will lay any) I´ll release some on the place they live in the nature.

I woke up Gittenbergeria turriplana those near extinction snails ( Red Book of Endangered Fauna) and then they started to mate! I´m happy.
