This underwater canyon is a significant geological feature of the Balearic Sea and plays an important role in the region's marine biodiversity.

It forms an area very rich in biodiversity, since its rocky walls are the shelter of an immense variety of organisms, some of which, like corals, sponges and gorgonians, are protected and in danger of extinction.

The upward currents that are generated in the canyon bring nutrients from the depths to the surface, which favors biological productivity and the presence of a rich marine fauna.

In 2017, as part of an ICM-CSIC project aimed at studying the effect of trawling on deep marine sediments, Pere Puig's team found a large number of colonies of coral in the Blanes canyon.

He did it with the help of other international researchers together with scientists from the Institute of Marine Sciences, who collaborated in the exploration of the canyon aboard the oceanographic ship of the CSIC, Sarmiento de Gamboa.
