Alpine Rustwort

The Alpine Rustwort (Gymnomitrion alpinum) is a species in the genus Gymnomitrion. Native to Europe, inhabiting ecosystems characteristic of the region. Distributed across Norway and Sweden.

Sleek semi-aquatic mustelid found along clean rivers, streams, and coastlines across Europe and Asia. European otters can reach 1.3 meters in length and are highly skilled fish hunters, using sensitive whiskers to detect prey movements. Requiring unpolluted water with abundant fish, they are an indicator species for freshwater ecosystem health. Once nearly extinct in Western Europe from hunting and pollution, populations have recovered significantly following water quality improvements.
