Baltic Sea as species in 2005 and 2018 respectively, having formerly been confused with more widespread relatives. The tiny Copenhagen cockle ("Parvicardium hauniense"), a rare mussel, is sometimes considered endemic, but has now been recorded in the Mediterranean. However, some consider non-Baltic records to be misidentifications of juvenile lagoon cockles ("Cerastoderma glaucum").

A peculiar feature of the fauna is that it contains a
Parting of the Waters Parting of the Waters Parting of the Waters is an unusual hydrologic site at Two Ocean Pass on the Great Divide, within the Teton Wilderness area of Wyoming's Bridger-Teton National Forest. Two Ocean Pass separates the headwaters of Pacific Creek, which flows west to the Pacific Ocean, and Atlantic Creek, which flows east to the Atlantic Ocean. At Parting of the Waters, at , North Two Ocean Creek flows down from its drainage on the side of Two Ocean Plateau and divides its waters more-or-less equally between its two distributaries, Pacific Creek and Atlantic Creek. From this split, Two Ocean
