re: #599 Jimmah

I don’t know what those particular adaptations are off hand, but it doesn’t take a genius to see that intermediate fresh/salt water environments - which are located intermediate between areas of fresh and salt water- estuaries and so forth - create ample opportunities for gradual adaptation from one extreme to the other.

I assume the adaptation pressures would be similar to the saltwater crocodile… The SW crocodile lives in fresh rivers and swamps, but in the dry season when these areas disappear they are forced to go out toward the sea.
