I find everything interesting, I am an expert on nothing. Currently obsessed with land snails and marine molluscs. Also spiders. I like photographing critters without bothering them too much (if that means they can't be identified to species level, so be it). Thank you for all IDs and comments.

Scale in photos: all rulers in cm/mm; the nail of my index finger is about 9mm wide.

Mainly as bookmarks for myself, but also in case it is useful to others, I list below some identification resources.


  • France: MNHN Biodiversicles app (Android app; allows filtering by region and by intuitive traits; with good photos of shells for all species + map for France; a great identifying resource inc for beginners; in French)
  • Iberia & Balearics: Cadevall & Orozco (2016) Caracoles y Babosas de la Península Ibérica y Baleares (excellent book for identification; with good photos of shells, sometimes of the live animal too + description + maps; in Spanish)
  • Global: (database of species; with some ID info + photos of shells; particularly useful to see a diversity of shells; in English)
  • Iberia & Macaronesia: (database with photos of shells + description + distribution maps; in Spanish)
  • Continental Portugal: Albuquerque de Matos (2014) Atlas dos Caracóis Terrestres e de Águas Doces e Salobras Portugal Continent (book; with photos of land AND freshwater species; maps in Atlas format; in Portuguese)
  • Global: IUCN Red List of Threatened Species (database of species, progressively getting more complete - many European species there already; not an ID resource, but useful for its global distribution maps; also conservation status, habitat, threats; in English).
  • Andaluzia: ICTIOTERM (database of common species, with good photos and a little description; in Spanish)
