Apps

The team behind this site have created, together with flores.nl a determination and reference app.
This app is currently only available in Dutch, but we are working on a Dutch/English version.

With this app and determination table you can determine all in the Netherlands found species of seaslugs without gillls (sacaglossa) and with gilles (Nudibranchia) . The West-European coast has over 100 species. Alhough there is a very small change, it might be the case that you find a new species that is not included in the app.

Many species are more or less variable in color or even in form. In this determination table we tried to only use the constitent external anatomic characteristics. Unfortunatly in some cases we had to use coloring as well.

We tried to built the determination keys in such way that it works on pictures. Still some species are almost impossible to determine using pictures only. For those we suggest to look at the complexes which describe the groups as a whole.

You can use your own pictures in the determination process. The app will request your permission to read your camera roll. U can deny this, but then you can't use your own pictures during determination. We do not collect any information and your pictures are not send to us, however in the future it might be possible to log observations via the app. In that case we will send data to our servers, only with your permission and with the purpose of our goals and not for any form of marketing.
