the strange inhabitants of the Antarctic abyss
In the frozen, forgotten depths of the South Atlantic, an international team of scientists has achieved the unexpected: confirming the existence of thirty completely new marine species for science. Among them, a creature stands out that challenges what we know about life in the deep ocean: a spherical sponge covered in hooks, capable of catching its prey with such forceful efficiency that the team itself baptized it as “death ball”. We don’t know everything. With this type of news, science places our feet in reality, since although we have been populating this planet for many years, there are still things that we do not know. An example are these new species that show us that in the depths of the ocean we have a great mystery for humans and that there is still a way to surprise us with our planet. A predator. Most marine sponges They are considered “peaceful”filter feeding and causing no further harm to anyone. But the Chondrocladia sp. novfound more than three kilometers below the surface near Montagu Island, uses microhooks that act as a kind of “deadly Velcro” on crabs and other invertebrates, which it slowly absorbs. Visually, this is a sponge that is actually quite surprising, since it is white and has appendages ending in small balls. In this way, it managed to gain the attention of specialists who have described it as one of the strangest animals of the entire expedition. This is something that breaks with what a traditional sponge does that we all have in mind, which simply feeds on particles and remains in the water itself. But this new species is committed to feeding on other living beings and on those that are above the food chainas the study researchers point out. Technology has been key. Right now, accessing the seabed is a real challenge for humans. One of the great impediments is the great pressure that exists in that environment that becomes really hostile. But thanks to technological advances it has been achieved. This specific investigation has had a underwater robot named SuBastian and high definition cameras. The result of the expedition was thousands of hours of video and nearly 2,000 specimens among the images that had to be analyzed. But the species were not the most notable part of this research, since new hydrothermal springs, coral gardens with volcanic structures were also discovered, and a juvenile colossal squid was recorded for the first time. Not just sponges. It is a fact that on the seabed there are many species that are truly strange, including the so-called ‘death balls’, but they were not alone in this rarity. Other species that surprised the researchers were the following: Zombie worms (Osedax sp.), capable of feeding exclusively on the bone tissue of whales and large vertebrates. Rare mollusks, bivalves and black corals adapted to hydrothermal and volcanic environments. A complicated process. Verifying that these findings are true is not something easy to achieve. In this case, the findings were made this August at the University of Magallanes in Chile where specialists from eight countries applied accelerated identification techniques: from in situ imaging to genetic comparison, in a process that seeks to reduce the years of waiting to catalog new species.
