Scientific discovery could save endangered Caribbean coral reefs

For the first time, marine biologists have successfully bred a type of Elkhorn coral coral formation The Caribbean.

This is an important step that could help revitalize the region’s ecosystems.

In addition, coral reefs provide a protective barrier during hurricanes by keeping coastlines from breaking waves. They are also refuges for fish and other species.

The elk antler was formerly the most common coral reef in the Caribbean waters. His condition has deteriorated significantly in recent years. Since 2006, it is even a protected species, because it is threatened.

However, Elkhorn coral is a primary species because these corals are the basis of reef formation. Usually, it does not develop in aquariums, hence the delight of the scientists at the Florida Aquarium.

Elkhorn coral has a complex structure with many large branches that are the main habitat of many coral inhabitants such as lobsters or parrots. Elkhorn coral colonies grow incredibly fast (5-10 cm per year) and can reach 3.50 m in diameter. Its color varies from brown to yellowish brown. It is caused by a symbiosis with zooxanthellae (algae) that live within the tissues of this coral. These algae carry out photosynthesis and provide the coral with nutrients.

It’s the first step in preventing the extinction of Elkhorn coral, said Keri O’Neill, director of the Tampa Laboratory.

It’s the 14th type of corals cloned in this lab, but it’s certainly the most important to the team of scientists.

According to Keri O’Neil, several hundred coral larvae were born from the experiment. She hopes that at least 100 people will reach the age of majority.

In nature, the birth of coral larvae is a wonderful sight.

Within two years, lab-bred corals will be transplanted to Florida’s reefs.

We save time…we save time for corals…and we save time for corals.

A vital necessity because in 2019, a UNESCO report indicated that 20% of the planet’s coral reefs have been destroyed. No signs of recovery were observed. The study also showed that 24% of coral reefs were exposed to a similar risk associated with human activities and 26% could present a similar risk in the future.

A disturbing discovery already indicates that these marine ecosystems, the most diverse in the world, could disappear before the turn of the century.

To preserve these environments, the Florida Aquarium hopes to establish a breeding program for Elkhorn coral, which can withstand threats such as pollution, warming oceans and disease.

Scholars refuse to be fatalistic and admit defeat. Their recent discoveries are heading in the right direction and could also be a hope for the reefs around the Guadeloupe archipelago.

There is hope in coral reefs. We must not lose hope. All is not lost.
