The phenomenon is impressive.
This weekend, a massive stranding of several thousand starfish occurred on the beach at the foot of the Dune du Pilat, in the Arcachon basin (Gironde).
Several photos and videos have been circulating since.
Depending on the year, the presence of starfish on the Gironde coast is more or less abundant, but such a phenomenon is extremely rare.
And remains unexplained for the moment.
“You have surely seen the photos of starfish washed up on the beach in recent days, say the officials of the Dune du Pilat on their Facebook page.
With the help of our partners, we are trying to find out more about this phenomenon (breeding period, strong sea currents, etc.)”
Don't handle them
On the other hand, “it is important not to manipulate the starfish because we do not necessarily see their movement with the naked eye.
They are still alive!
Leave them on the beach.
The proof in pictures, since the Dune site has published a video of a moving starfish.
The common Starfish or "Red starfish (Asterias rubens)" of its real name, can live four or five years.
Depending on its habitat, it can measure up to 30 or even 50 cm in diameter.
