Posting to Facebook, Alan Deidun shared images by Bjorn Schembri of a Marsaxlokk beach utterly covered with empty bivalve shells, such as those of cockles and clams.
The bivalve shell is part of the body, the exoskeleton or shell, of a bivalve mollusk. This is a class of, in this case, marine molluscs that have laterally compressed bodies closed up by a shell consisting of two hinged parts.
The extraordinary sight, Deidun speculated, was due to the strong South-East winds which ‘pummelled the area in recent weeks.’
The strong weather patterns likely dislodged all form of burrowing creatures which were sheltering within the soft seabed of the embayment. Deidun described it as a rare sight.
Some interesting facts about these molluscs is that they appeared in the fossil record more than 500 million years ago and there are about 9,200 living species of them.
