"Camps finances" in La saline lagoon, 7 february 2007, less than 1 m.

During a few days we observed in the lagoon of Saint Gilles, just near the beach, a great mass spawning event. We found a lot of specimens (between 30 to more than 100 per m2) in several large patches near the beach. Usualy we don't observe this species in this area.

This event was onberved by several people in Saint Gilles lagoon during a short period (about one week)

The algae seems to be Caulerpa racemosa.

If conditions are good, many cephalaspideans, like the anaspideans, can quickly develop large local populations, but usualy their behaviour was much more restrained

Each spawn consists in a jellylike tube on whose surface a long chain of white egg mass can be observed
