Some nudibranch* photos from the dives with @vivia end of June near Ammouliani, Greece.

Featuring: Two white-dotted yellow Phyllidia flava on an orange sponge, a blue-purple Flabellina affinis, a white-blue-red-orange Cratena peregrina.

And a bearded fireworm, while not a nudibranch, it also has a long shape. Do not touch, it is going to hurt a lot for hours 😱​
