Huge 800-year-old coral colony identified in Red Sea

  • The discovery, off the northwestern coast of Saudi Arabia, is said to be one of the largest of its kind in the world
  • It is expected to become a carefully managed tourist attraction for visitors to the Red Sea Global resort of Amaala

JEDDAH: A massive Pavona coral colony has been discovered in the Red Sea, off the northwestern coast of Saudi Arabia. The largest of its kind ever identified in the waters, it is expected to become a tourist attraction at the nearby Red Sea Global resort of Amaala.

This standalone colony — in contrast to a much larger reef, which is made up of many individual colonies — was described as one of the most significant environmental discoveries in the region and, although an exact size was not immediately given, it was said to rival the world’s largest-known individual coral colony, which is in the Pacific Ocean, covers an area of 32 meters by 34 meters and is 5.5 meters high.

Red Sea Global told Arab News it will offer visitors to the Amaala resort the chance to view the colony in a secure and environmentally responsible way that ensures it is properly protected and minimizes effects on the local ecosystem.

Ahmad Al-Ansary, the organization’s head of environmental protection and regeneration, told Arab News that “a discovery of this magnitude underscores both the Red Sea’s environmental importance and its natural beauty.”

The discovery, off the northwestern coast of Saudi Arabia, is said to be one of the largest of its kind in the world.

Estimating the age of the colony poses a technical challenge because of the limited growth-rate data for this species of coral in the Red Sea. Based on its size, comparative growth rates from Pacific specimens, and photogrammetry techniques that create 3D models from two-dimensional images, conservative estimates put its age at between 400 and 800 years old. Red Sea Global and KAUST said they were carrying out additional research and will refine the estimate.

“These giant coral formations act as ‘time capsules,’ preserving critical data on past climate conditions and helping us anticipate future environmental challenges,” he added.  

He went on to say that studying this colony will be essential for safeguarding coral reefs in the Red Sea and around the globe.

Red Sea coral ecosystems are among the hardiest in the world, genetically adapted to relatively high temperatures and salinity, and researchers said they will continuously monitor the colony to understand the nature of its resilience.

Ronda Sokka, a marine scientist at Red Sea Global and a co-discoverer of the colony, described it as “a natural treasure whose incredible hardiness in harsh conditions is truly rare.”

Her colleague Sylvia Yagerous said that mapping and documenting such large colonies is a core objective of the “Map the Giants” project, which aims to record all coral formations worldwide exceeding five meters in size. The latest find is the second giant colony documented by Red Sea Global in recent months.

Shaping future society: How intellectual forums contribute to cultural development

RIYADH: Modern nations do not transform on technological progress alone, but evolve through various factors such as values, religion, culture and assumptions that guide how societies interpret development.

Philosophy is one aspect of understanding civilization. Although it is often seen as abstract or far from reality, it plays an essential role in shaping a nation’s understanding of modernization.

It impacts how people see progress and discuss cultural identity, along with measuring the ethical implications of joining the global mindset.

Yet, by examining the philosophical thoughts that shape national narratives, people gain a deeper understanding of why societies adopt certain ideologies for development, resist others, and struggle to balance tradition with innovation.

Saudi Arabia, for example, defines its place on the global stage and navigates the complex tensions between heritage, aspiration and global responsibility through its own philosophy.

The Philosophy Forum, organized in Riyadh this week for the fifth year, witnessed the attendance of both local and international thinkers. During the conference, some Arab philosophers shared their beliefs in the idea that there is no absolute truth; while other philosophers differed, considering the Arab view on truth, culture and relativism.

“We must distinguish between the existence of relativity in science — the world is changing because it is relative — and our belief in absolute truths within our culture. For example, the only truly absolute thing in the world is death, which is mentioned in the Holy Qur’an,” Essam Gameil, professor of logic and critical thinking at Cairo University, told Arab News on the sidelines of the forum.

He added: “Our morals are unchanging; ethical principles are fixed. For example, respecting others is a fundamental principle; how can it be altered?

“Some concepts can be changed within the framework of science, but not in the humanities, not in religion, not in ethics. There are constants.

“It is the moral principles and rules that drive me forward,” Gameil said, adding that philosophy was created to solve issues that occurred in society during the time of Aristotle and Plato.

“It appeared to solve social problems … it was created to address lying, deception and more. Socrates was a moral philosopher and nothing else,” he said.

Gameil described Saudi Arabia as an example of “an extraordinary leap” in the Arab world in terms of development and philosophy.

He said that the Kingdom’s interest in philosophy and its organization of a major conference in the field stems from a crucial concept discovered by the Saudi leadership, which is that humanity has two aspects: A spiritual aspect and a material aspect, represented by the body.

“Studies typically focus on the body — artificial intelligence, engineering, and so on — but have often neglected the spiritual dimension. Philosophy is a human science; the more you emphasize it, the more certain concepts become firmly established and ingrained,” said Gameil.

Eman Al-Mulhem, a researcher in the philosophy of science at King Faisal University in Al-Ahsa, believes that the Kingdom’s situation presents three very promising paths: The philosophy and ethics of artificial intelligence, science and technology studies, and a re-reading of the Arab philosophical heritage using contemporary methodologies.

“This field is no longer a luxury, but a necessity. The question is no longer: What can a machine do? Rather, it has become: How do we preserve our humanity in a world where we share the power of decision-making with machines?” she said, highlighting the philosophy and ethics of AI.

She added: “We have a rich heritage, but we need modern tools to understand and reconstruct it, not just explain it. These fields are not only promising, but they are also capable of reshaping the role of philosophy in the Arab world.”

Al-Mulhem also works to connect Arab philosophical heritage to questions of contemporary science. She believes that philosophy is not detached from reality, but rather helps to reevaluate our relationship with science, humanity and the world.

On the question of whether Arab philosophical heritage is still suffering from global misconceptions, she said: “(It) still suffers some global misconceptions, such as being reduced to a mere extension of Greek philosophy or a stagnant tradition.”

However, the Riyadh International Philosophy Conference, which hosts philosophical minds from around the world, is helping to correct this image, she added.

“They present Arab heritage in a dynamic context, through the voices of its own scholars. At this conference, the world encounters Arab thoughts that engage in dialogue, produce ideas and critique — not as a static heritage, but as an integral part of contemporary global philosophy,” said Al-Mulhem.

“Philosophy is not far removed from humanity; it is closer than we imagine. Every question we ask, every attempt to understand the world, is a philosophical step,” she said.

“I believe that the Arab region today has a great opportunity to reclaim its role in producing knowledge, not just consuming it. And the Arab researcher is capable — given the right environment — of making a lasting impact that transcends geographical boundaries,” she added.
