A Dangerous Venomous Sea Urchin Is Spreading in Cyprus

After the appearance of pufferfish and lionfish in Cyprus, specialists are recording the spread of yet another alien marine species — the sea urchin Diadema setosum. In recent years, it has been seen more and more often along the island's coast.

This species is distinguished by its very long spines, which can reach 30 centimeters. They contain a weak toxin, so a sting can cause severe pain.

The dangerous sea urchin is most often observed in the Polis and Latsi area, as well as on breakwaters and rocky shores. According to specialists, the species reached the Eastern Mediterranean from the Indian Ocean through the Suez Canal.

Scientists believe that the spread of Diadema setosum is facilitated by rising sea temperatures, as well as changes in the marine ecosystem and overfishing.

In addition, the new species is gradually displacing local sea urchins. According to specialists' observations, in some areas of Paphos, where they used to be abundant, they are now found much less frequently.
