An image archive for LIFE Pinna

The naturalist photographer Marco Colombo has documented some aspects of the natural history of Pinna nobilis. The large bivalve mollusk, protagonist of the LIFE Pinna project, is portrayed in different underwater contexts, often together with other organisms with which it has developed complex relationships.
The images are owned by Marco Colombo and Triton Research and can only be used for the promotion of the LIFE Pinna project.

The noble pen shells (Pinna nobilis) rise up to one meter from the seabed and, when they are present, they are easily spotted by those who dive.

With the epidemic that has hit the noble pen shell populations (Pinna nobilis), large concentrations of molluscs, as in this photo, are increasingly rare.

The noble pen shell shrimp (Pontonia pinnophylax) an extraordinary crustacean, about 4 cm long, which can live inside the largest fins, feeding on food particles collected by the mollusk. It is a great example of the complex relationships that Pinna nobilis has developed with different marine organisms.
