HI,
I found this sponge in a dark crevice close to the surface. It does not quite look like Phorbas tenacior. Any ideas please?

Bonjour,
Il y a d'autres exemples de Dysidea fragilis bleues.
Par exemple https://www.inaturalist.org/observations/179183007

Thank you very much for your help.
Yes indeed the description of Dysidea fragilis matches is very similar. The only strange thing is that none of the descriptions refer to a blue form. I will keep looking.
Good day,
Desirée
