You'd better not tell the freshwater ones that they are supposed to be marine
or they might all go and commit suicide. :-)

Impossible to know for sure.

Do a phylogeny based on a number of different data sets then see where the
data agree and disagree and then make an unbiased arbitrary decision as to
what you think it all means.

I've seen a little bit on the Indian species but that's all. I don't have the
reference, but a literature search will find it pretty quickly.
