Scientists warn pathogen killing sea urchins spread to Indian Ocean threatening coral reefs

Researchers at Tel Aviv University (TAU) have identified a pathogen that caused large-scale death among sea urchins in the Red Sea and warns its spread to the Indian Ocean threatens the coral reefs across the planet.

Sea urchins feed on the algae that compete with corals for sunshine, making them the so-called “gardeners” of the reefs. Their disappearance could have a massive impact on the natural balance of the already endangered underwater ecosystem.

The scientists from TAU’s School of Zoology and the Steinhardt Museum of Natural History (SMNH) first identified the epidemic last year in Israel’s Red Sea city of Eilat, where the pathogen has essentially eradicated most of the sea urchins.

Since then, it has spread across the Red Sea and into the Indian Ocean, transforming what was a local phenomenon into a potentially disastrous worldwide pandemic – threatening coral reefs across the globe.

The researchers believe that since the start of the epidemic in December 2022, most of the sea urchins in the Red Sea have been wiped out, and an unknown number of the creatures have also died worldwide.

“This is a growing ecological crisis, threatening the stability of coral reefs on an unprecedented scale. Apparently, the mass mortality we identified in Eilat back in 2023 has spread along the Red Sea and beyond – to Oman, and even as far as Reunion Island in the Indian Ocean,” said Dr. Omri Bronstein of TAU, who led the study.

“The deadly pathogen is carried by water and can affect vast areas in a very short time. Even sea urchins raised in seawater systems at the Interuniversity Institute for Marine Sciences in Eilat, or at the Underwater Observatory, were infected and died, after the pathogen got in through the recirculating seawater system. As noted, death is quick and violent,” he said.

“Moreover, until recently, only one species of sea urchins was known to be impacted by this pathogen – the Caribbean species. Today we know that additional species are susceptible to the disease – all belonging to the same family of the most significant sea urchin herbivores on coral reefs.”

Published

The rural agricultural livelihood and food security have been severely impacted due to the damage caused by wild animals such as elephants, wild boars, monkeys, toque macaque, squirrels, and peacocks roaming around human habitats and cultivated lands.

Animal-human conflicts and property destruction have mostly been reported around these areas, and serious social and economic issues have also arisen.

Therefore, the Ministry of Agriculture, Livestock, Land, and Irrigation has prepared a comprehensive program based on the opinions of all stakeholders, including the public, university community, farmers’ organizations, environmentalists, non-governmental organizations which work for environmental issues, the Department of Agriculture, the Department of Agrarian Development, and other relevant organizations.

Taking into consideration the report submitted by the Minister of Agriculture, Livestock, Land, and Irrigation, the Cabinet of Ministers has decided to appoint a ministerial committee with the participation of other relevant ministers, chaired by the Minister of Agriculture, Livestock, Land, and Irrigation, to submit appropriate recommendations on how the aforementioned program should be implemented by further reviewing the proposals included in the said program and incorporating new proposals.
