Cetaceans mammal list rankings

Although there is much more to mammalwatching than listing species, it is – for many of us – a fun way to track our effort. Mammal listing is nothing more than a friendly competition. But I believe it can motivate mammalwatchers and also lead to a more interactive and lively community. So if you have a list please share it here. Any questions about what people have seen or where? Just click on their list and ask them. And if you are feeling motivated to add to your list then check out this post on where to see (most of) all the world’s cetaceans.
