Cytherissa lacustris, Rare tiny creatures found in loch near Kinross

Tiny crustaceans previously recorded at two locations in the British Isles have been found in a loch near Kinross.

Cytherissa lacustris, a species of creature called ostracods, only grow to about a millimetre in length.

Until now, this species had only been known to be living at Loch Assynt in Scotland and a site in north England.
