Noble pen shell. Nacra

Great spotting! Congrats, Eulalia.

Congratulations Eulalia, your noble pen shell is featured as our Spotting of the Day: "Our Spotting of the Day, the noble pen shell (Pinna nobilis), is the largest and most emblematic mollusc of the Mediterranean Sea. As a filter feeder it plays an important ecological role in contributing to water clarity. Yet a recent drastic reduction in its population has led to its listing as an endangered and protected species by the European Council. In the salt-water coastal lagoon of Mar Menor (Murcia, Spain), where this spotting was made, an area with more than 50 live specimens has been found which has now been fenced off by protective nets. Make sure the check the spotting for more images, a video, and plenty of detailed information about the mass mortality event of Pinna nobilis. Project Noah is grateful to Eulalia and her sister Isabela for continuing to report about conservation efforts at Mar Menor.

Congratulations, Eulalia, for this nomination. Pinna nobilis is not an attractive or beautiful species such as butterflies, birds, little mammals, etc, but it is important to raise awareness of the importance of its protection. They are the largest mollusks in the Mediterranean sea; they filter large amounts of detritus and retain a high percentage of their organic matter. They provide a surface that can be colonized by other species as you can see in Eulalia's photos (sea anemones and algae). In the past buttons and other jewelry objets where made from the mother pearl of this bivalve. Besides in the antiquity, gloves where also made with the fibres (sea silk) which hold this mollusk to the bottom of the sea.

Such a sad situation. I hope we are not looking at a dead mollusk walking. So many of our species are facing this. Thank you so much Eulalia for sharing this with us.

Yes I want to draw some eyes on photo 3.

I especially like the third photo

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

So interesting Eulalia! I'll make sure to bring this to attention.

Excellent photo series! Thanks.

Great series of this species in extreme danger of extinction. This is the biggest mollusk in the Mediterranean sea where most of its population has died. https://www.frontiersin.org/articles/10.3389/fmars.2017.00220/full However in the coastal lagoon Mar Menor a number of them have been found alive! You can see them in Eulalia's photos.
