Scotland: Biologists search Firth of Clyde for "priority marine features" in MPA project
Marine biologists are surveying the Firth of Clyde in the hope of confirming the presence of Scotland's most important underwater wildlife.
Scientists are searching for priority marine features (PMFs) - species and habitats of conservation importance.
These include horse mussels, flame shell beds and rare creatures such as the fireworks anemone.
The survey forms part of the Scottish Marine Protected Areas Project, investigating Scotland's seas.
