A recent study published in Nature has unveiled the astonishing discovery of giant worms residing beneath the Earth's crust in the depths of the ocean. This finding suggests that deep-sea ecosystems are far more extensive than previously believed.
The research team explored the East Pacific Rise, located off the coast of Central America, at a depth of 2,515 meters. Here, two tectonic plates are moving apart, creating hydrothermal vents that release heated, mineral-rich water.
These underwater oases, discovered only in the 1970s, host unique biodiversity, including giant tube worms and mussels that thrive under extreme pressure and complete darkness, in symbiosis with bacteria that produce nutrients from minerals.
The scientists aimed to understand how the larvae of these tube worms rapidly colonize new hydrothermal fields after eruptions. They hypothesized that the larvae might be transported with cold water into the crust, mixing with fluids from the vents before being expelled to the surface.
Using a remotely operated underwater vehicle equipped with cameras and drilling tools, the team collected samples and uncovered rich populations of microbes, larvae, and adult worms in cavities beneath the ocean floor.
Professor Monika Bright from the University of Vienna emphasized the importance of identifying these organisms to protect them from deep-sea mining, highlighting the unique nature of this fauna.
This groundbreaking research underscores the potential for unexpected discoveries in well-studied areas and the need for conservation efforts to preserve these unique ecosystems.
