I first found this Nudibranchs Syphonota geographica at sand bottom 10m deep in Seririt.
After mailing it to the Australian world expert Mr Neville Coleman for research, I received his reply two months later informing that it is a NEW NUDIBRANCH ! It is now included in Mr Colemans' publication NEW "ENCYCLOPEDIA OF NUDIBRANCHS" edition 20008, page 64.
