Aegires palensis from French Mediterranean

Dear Bill,

I'd like to share with you and Forum participants these photos of Aegires palensis. I found this 4 mm long animal on the French Mediterranean coast, on a shallow rock covered in fixed fauna, amongst Posidonia.

Locality: " L'Estagnol ", Bormes-les-Mimosas, 3m, France, Mediterranean, 17 September 2009, rocks and Posidonia. Length: 4 mm. Photographer: Marina Poddubetskaia.

Lucas Cervera identified this animal and Terry Gosliner confirmed this ID from photos. Lucas Cervera told me this species have never been seen since its description in 1990. And it seems there isn't known photo of living animal.

Best wishes,

Dear Marina,

Thanks for this interesting find. As you say, we know very little about this species which is known from the original 6 mm long specimen and a second 2 mm specimen reported by Fahey & Gosliner (2004). The dark brown markings on the boody and the banding on the rhinophores may turn out to be good identifying characters when more material is available.

Best wishes,
Bill Rudman
