A team from CONICET identified a new species and a new genus of sea urchin in the submarine canyon of Mar del Plata. Consequently, the discovery expands knowledge about life in deep waters.
The specimen, named Bathycidaris argentina, was found between 1100 and 1950 meters deep. There, the extreme conditions challenge the survival of the majority of species.
Additionally, the research was led by specialists from IBIOMAR-CONICET and the Argentine Museum of Natural Sciences Bernardino Rivadavia. In this way, a scientific work of national scope was consolidated.
An extreme and little-explored ecosystem
The Mar del Plata canyon is located on the edge of the Argentine sea, south of the mouth of the Río de la Plata. Therefore, it constitutes a strategic area from an ecological point of view.
It is a submarine system that extends about 250 kilometers offshore. Additionally, it reaches depths close to 4000 meters.
In this environment, darkness, low temperatures, and high pressure prevail. However, these conditions favor the existence of unique biological communities.
Likewise, the interaction of currents turns the canyon into a biological corridor. This facilitates the circulation of nutrients and organisms.
Characteristics of a unique species
The discovered urchin measures just 2 centimeters wide and 1 centimeter high, not counting its spines. Consequently, its small size contrasts with its biological complexity.
One of its particularities is parental care. The females protect the embryos near the mouth until they develop.
On the other hand, its spines serve a key ecological function. They provide support for other organisms, such as worms and marine colonies.
Thus, the species not only survives in extreme conditions. It also contributes to the structure of the benthic ecosystem.
Environmental consequences and scientific value
The discovery highlights the importance of preserving deep marine ecosystems. Indeed, these environments still hold much of their unknown biodiversity.
Additionally, it evidences the need to regulate human activities in the ocean. The exploitation of resources could affect species that are still unstudied.
On the other hand, the discovery provides key information to understand the evolution of marine life. Each new species allows for the reconstruction of complex biological processes.
Likewise, it strengthens scientific research in Argentina. The sustained work over more than a decade demonstrates the value of oceanographic exploration.
Research and future challenges
The discovery was made possible after campaigns conducted aboard the Puerto Deseado ship. For years, scientists collected samples at extreme depths.
Subsequently, the analyses combined morphological and genetic studies. This allowed confirming that it was an unknown species.
In this sense, technological advancement is fundamental. New tools facilitate the exploration of inaccessible environments.
Finally, the discovery opens new questions. As studies deepen, the ocean reveals its central role in the environmental balance of the planet.
