Pruvotfolia sp. (undescribed)

Well I am guessing that this is a new Pruvotfolia based on ceratal morphology and the perfoliate rhinophores. My only problem is I have never seen this species and it not even close to anything in NSSI 2ed Edition. It is entirely distinctive.

The body and cerata are sort of orangish- green and the digestive gland is dark. The cerata have a bright purple subapical band and are tipped with bright orange. There is a touch of the same purple anterior to the rhinophores. A cnidosac is clearly apparent at the tip of each ceras.

It is hard to believe that with all the photographers and slug-o-philes diving the Lembeh Straits, we haven't seen this guy before. If anyone has, and has been keeping it a secret, please let us know.

Webmaster's Notes:

"..Zeineb Alhaidari is a veterinarian , specializing in dermatology , living in the south of France , on the Mediterranean seashore. Zeineb started diving in 2001 , and realized it was a wonderful way to get away from stress. she became addicted , and developed an early interest in marine biology , thus giving her "better eyes" for underwater photography. Zeineb was fortunate to have as her backyard the Mediterranean sea, which is a wonderful and endless game of field, and she loves small creatures. Zeineb has joined a small association of underwater photographers, the Aquanautes (, and her u/w camera is an Olympus OM-D E-M5 Mark II in an Olympus housing with a single Inon D 2000 strobe..."
