This a reference for "The acrorhagi are almost invariably bright blue, occasionally white or pink" in Actinia equina:

Maybe it is A. striata, I do not know well the Phylum Cnidaria, but the blue margin at the very base it seems irrelevant.

???
Actinia schmidti (ex-Actinia equina) has always a blue margin at the very base, often visible.

yes Roberto, you may be right

but a blue margin at the very base (very visible in the initial image) has, as far as I am informed, only been described/observed in Actinia striata.

Awaiting, as you adviced, genetic studies and new results, the simpliest solution is to consider this as an image of Actinia striata

I think it is Actinia sp., it is different to Actinia striata and it is different to Actinia schmidti (ex-Actinia equina).

I often encounter this species in the south of Corsica or in Northern Sardinia. I've never encountered it in other places.
http://doris.ffessm.fr/forum_detail.asp?forum_numero=9618

I met and photographed Actinia striata in Menorca, it is different: smaller, with less banding, thick lines and color much darker banding.
http://doris.ffessm.fr/forum_detail.asp?forum_numero=9617

I think that these examples are probably Actinia cf. schmidti strangely colored. The main reason is that there are examples too large for A. striata and various specimens with intermediate colors.
I think that need genetic studies for to give a name to these specimens. I post some sample photos.

Merci Frédéric! I did a google search and it looks exactly like Actinia striata. New species for me:)

Bonjour Désirée,

je pense à l'anémone proche de l'anémone cheval : Actinia striata Quoy & Gaimard, 1833, http://doris.ffessm.fr/fiche2.asp?fiche_numero=2410
