I found this nudibranch in a tidepool in Italy (Ancona)
Size 1 cm, depth 20 cm

Alberto, your animal looks like Aeolidiella sanguinea, but usually, in this species the tips of rhinophores are obviously white. In your animal it isn't obvious, just some pale tinge at the very end.

I edit this photo just for contrast and light, colors are natural,
You're right.. this photo maybe is better, showing cerata and the dorsal side

Hi Alberto, it's not easy to ID animal from an artistic shot. I would need to see more characteristics, other than "orange eolid without white lines".
Do you have other photos of it, please ? Does its colour is real or is it just a light effect ?
