Sea Cucumber

submitted
filed under Photos

This is a picture of a sea cucumber I saw when snorkelling at Mgarr ix-Xini, Gozo. This strange looking creature intrigued me as I had never seen anything like it. It belongs to the group Echinodermata which are often found on sandy sea beds. Sea cucumbers are sausage like creatures, around 30 to 40 cm long, with bumps or spines on their leathery skin. They feed on tiny creatures, plankton and algae. They are harmless but when they feel threatened they contract and shoot out water. They can also secrete a very sticky substance which acts like glue and if it gets on your skin it’s almost impossible to remove. Sometimes, in defence, they even shoot out their internal organs and then grow them back again. Sea cucumbers are considered as a delicacy in Chinese cuisine and some even believe they are aphrodiasiacs.

Bring to light the Verdala Spire

submitted
filed under Photos

A dominant feature of the Verdala Retrenchment, on Margherita Hill in Cospicua, built during British times is a unique spire on top of the hall. The hall dates back to the years 1871 – 1874. The spire by HB Evans is the only Victorian spire found in Malta. The premises were restored recently. However the metal cover of the spire needs special treatment to avoid corrosion by rusting. If rain, manages to penetrate, being acidic it will rot the wood causing chemical weathering as we learnt during our geography lessons. We interviewed persons working on site. They have made several attempts to create awareness about this unique spire. They suggested that the metal cover of the spire should be given constant professional maintenance and then light it up at night. If lit up, the spire will be a focal point for it can be seen from the Upper Barakka Gardens.

Shaken and rattled by quarry blasts

submitted
filed under Photos

The Naxxar quarry limits of Mosta is very close to the habitat, about half a kilometre away from homes. According to people living in the vicinity, the quarry blast explosions are causing vibrations to buildings, quite like earthquakes. Apart from this, these explosives used in hard stone quarrying are threatening the stability of valley slopes and damaging the archaeological cart ruts found in the area. These quarry operations are producing air pollution, and dust contamination. After interviewing some local people, I’ve discovered that lots of reports were made to the police and to the Naxxar and Mosta Local Councils but people living in the area said that no actions have been taken by now. Does anyone measure vibrations within the area of the quarry? Does anyone care about the effects caused to the people living close by? Immediate action is needed.
