Dear Colleagues, My master degree research project is about the morphology of the male reproductive organs of the tucuxi dolphin, *Sotalia fluviatilis*. So I'm searching for papers about the morphology of the male reproductive organs in Cetacea. I will be very grateful if you could help me sending some references or PDF files. I'm having some difficulty to find these references, as some of those are very old and difficult to find. Regards Simone M.
