Dr Anjani Ganase, coral reef ecologist, compares coral ecosystems of the Red Sea and the Caribbean. Coral scientists around the world are monitoring their native reefs as well as those that have adapted to higher temperature, looking at coral refuges. In the Old Testament, the passage through the Red Sea is a miracle created by God, to allow the Israelites to leave Egypt, led by Moses. The Red Sea was first explored by the Egyptians and Greeks looking for routes for trade between Africa and Asia. It is not a large body of water, in fact, it is one sixth the size of the Caribbean Sea, but it is long (2,250 km) and narrow (355 km wide – distance between Trinidad and St Lucia) stretching from the Gulf of Suez, where the Suez Canal connects to Mediterranean Sea. To the south, the Red Sea flows into the Indian Ocean. Geologically, the Red Sea is part of an extensive rift system that runs north–south all the way down the African East Coast to Mozambique, and is part of t...

  When last did you see black sea urchins on Tobago reefs? Anjani Ganase reports on the fate of sea urchins in the Red Sea following fatal disease in the Caribbean   Scientists are in shock after discovering a mass die off event of the black sea urchin (Diadema setosum) in the Gulf of Eilat in the Red Sea over the last couple of months. On reefs that were covered in these urchins, they now encounter dead skeletons and spines on the bottom. This black urchin, which is native to the Red Sea, invaded the Mediterranean Sea through the Suez Canal many years ago. The population which occurred in the thousands on the reefs in the Mediterranean were wiped out in July and August 2022. The first reports of the sea urchin mortality came from Greece and Turkia and was originally thought to be a localised event. While that die off did not seem a threat to the species that is invasive in the Mediterranean Sea, the rapid spread of the disease across thousands of kilometres in the Eastern...
