Species Profile
Parvicardium hauniense is a species of mollusc, known as Copenhagen cockle. It is an endemic species to the Baltic Sea.
The Copenhagen cockle faces significant threats from habitat degradation in shallow marine environments due to coastal development, pollution, and climate change impacts. Its restricted distribution in northern European waters makes it particularly vulnerable to localized environmental changes and human activities that alter sediment composition and water quality.
