A new species of crustacean that frequents the deepest depths of the North Pacific has been discovered by two researchers, Torben Riehl, from the Senckenberg Naturmuseum, a German natural history museum, and Bart De Smet, from the University of Ghent.
The new species has been named Macrostylis metallicola (the second term is due to the rock band Metallica, of which Riehl is a fan).
This crustacean was discovered in the Clipperton fracture zone, a marine area off the coast of Mexico. It lives at great depths, between 4000 and 5000 meters, a marine area where the pressure is over 400 meters higher than we experience on the surface.
It is a small crustacean that does not exceed 6.5 mm in length and lives almost in absolute darkness. This is precisely why it has not developed eyes and its body has no colour.
It lives in an environment where manganese nodules dominate, metal elements often millions of years old that can vary greatly in size and contain precious elements such as copper, cobalt, manganese, nickel and rare earths.
In fact, it is expected that the seabed area of the Clarion-Clipperton fracture zone (CCFZ) in the Eastern Central Pacific Ocean may be exploited in the future because of its wealth of manganese nodules.
It is precisely with regard to the exploitation of environments that until a few decades ago no one would ever have thought to reach to extract minerals that the researcher Riehl intends to carry out a form of awareness raising: “Very few people are aware that the vast and largely unexplored depths of the oceans are home to bizarre and unknown creatures, just like our new crustacean Metallica. These species are part of the Earth’s system on which we all depend. The deep sea plays a role in this system linked to the climate and food networks of the oceans. While we cannot prevent mining, we must ensure that the exploitation of the manganese nodule is carried out in a sustainable manner by implementing appropriate management plans and protected areas designed to preserve biodiversity and ecosystem functioning.
