Prevalence of trilobites in Austria?

Triops, saline cancers, fairy-cancers or shellfish are mainly found in saltwater lakes and ponds in Austria. These waters are located in salt mines, salins or salt gardens. A well-known example of a salt pond in Austria in which these animals occur is the Attersee in Upper Austria. Another example is the Altausse lake in Styria, known for its fairy-cancers. There are also some artificially created salt ponds that are specifically used for breeding these animals, such as Salzburg. However, it is important to note that these animals are protected in nature and must not be collected without permission.
