From Grado to Venice, a vivid and colorful treasure hides under the greenish surface of the open sea.

These are innumerable rocky outcrops, of various sizes and irregular distribution, which rise suddenly from the sandy seabed of the Upper Adriatic, several miles from the coast.

Locals in Friuli Venezia Giulia call them “trezze”, “tegnue” in Veneto, they are amazing reservoirs of life, fundamental places for the reproduction and feeding of marine fauna.

These rocky substrates are colonized by many invertebrate organisms, such as corals, sponges, and colonies of ascidians, which in turn create the ideal habitat for the survival of many other species, including our bivalve mollusk.

On May 24th the trezze off the coast of Grado will be the scene of an event organized as part of the project “Warm Sea” by Greenpeace Italia, in collaboration with Area Marina Protetta Miramare, Istituto Nazionale di Oceanografia e di Geofisica Sperimentale – OGS and Shoreline that for the projects TRETAMARA and LIFE PINNA deal with species and habitats of extraordinary importance to our sea; a valuable opportunity to dive in search of living specimens of the largest mollusks in the Mediterranean.
