Specimen of Scutella subrotunda (Leske, 1778) from the British Natural History Museum, E16593
This changed environment meant that the seabed was now subjected to stronger currents than before, therefore waves would drag large amounts of debris from deeper waters and deposit them onto these shallow reef-like platforms nowadays called the Maltese Islands.
