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.

Once nearly extinct in Western Europe from hunting and pollution, populations have recovered significantly following water quality improvements.
