[MARMAM] Wanted: cetacean ID key

Hello, I am trying to obtain a cetacean ID key for the identification of cetacean carcasses and skeletal remains. These are mostly to ID stranded animals. I have a copy of the FAO Species Identification Guide, Marine Mammals of the World (1994 I believe) but would wondered if there were any other keys available. Also, I would appreciate if someone can confirm whether all delphinidae species, with the exception of *Steno, *have smooth teeth as I have not seen descriptions of the surface texture of delphinidae teeth other than those of *Steno*. If you have any information please contact me at alesha.r.n@gmail.com. Thanks Alësha Naranjit
