Strange malleable rocks surfaced at Tanjung Bungah beach a couple of weeks ago. These videos were taken by a concerned visitor, Andrea Briglia, on 28 January at around 6pm.
One theory is that these could be balls of marine clay, material from the bottom of the sea found along the West Coast of the peninsula. These could have been dislodged when sand on the surface of the sea bed was sucked out – or something else could have stirred it out to the surface.
Another theory is that the mud balls are the result of land reclamation which has been going on in a big way since the 1990s. Reclamation material is a mixture of sand and mud, which is then deposited at the bottom of the sea nearby.
Any other theories out there?
It is important for the Department of the Environment to find out what is the source of these ‘rocks’ and how it is affecting marine life along the northern coastline of Penang Island.
