The probable culprit of the epidemic is a disease-causing ciliate parasite that brings with it a fast death. Researchers say a report to environmental authorities has been submitted and that emergency steps to protect the coral reefs are being examined.

Their findings, published in two peer-reviewed journals, cite mass mortality in other countries in the region, including Jordan, Egypt and Saudi Arabia. While that was less concerning at first since they were an invasive species, the pathogen has now crossed back into the natural population in the Red Sea.But there is a "very narrow window", he said, to create an isolated population, or broodstock, of the sea urchins remaining elsewhere that could hopefully be reintroduced later on.

Swift, deadly epidemic kills all the black sea urchins in Gulf of Eilat, posing threat to Eilat's coral reefA series of new, disturbing studies from Tel Aviv University reveals a deadly epidemic causing mass mortality of black sea urchins in the Mediterranean Sea and the Gulf of Eilat. The entire population of black sea urchins in Eilat was wiped out over a couple of months. For example, thousands of sea urchins living in a site near the northern shore of the Gulf of Eilat died out over the course of a few weeks. The epidemic was so severe, that today no living black sea urchins have remained at the site, only skeletons. The same has happened at other sites in the Gulf of Eilat. The studies note that such extensive mortality is also occurring in other countries in the region, including Jordan, Egypt, Saudi Arabia, Greece, and Turkey.
