Comment from Marta Pola on photo #2346
Comment from Dr. Marta Pola: I would say that this species is Tambja tentaculata. In this picture you can appreciate very well the lateral slot on the side of the head (Characteristic of some Tambja species) and also the oral tentacles, which are larger than in other species of Tambja.Comment from Dr. Richard C. Willan: An undescribed species.

This is not so clear. I would say it could be Tambja tentaculata because of the large developed oral tentacles and the color pattern but I haven't dissected any specimens like this.Locality:
