  2. I saw the pink dolphins many times while I was traveling up the Amazon. Amazing, they adapted to fresh water. I know otters species have done this also. Beautiful animals worth protecting.
    Thanks for posting,

    • Hi Cindy, thanks for reacting!

      Freshwater dolphins in South America (and in Asia) indeed evolved from marine ancestors (their ancestors, again, had evolved from land mammals over 50 million years ago).

      Otters, on the other hand, first evolved in fresh water, from weasel-like land mammal ancestors. Only the sea otter adapted to the sea later.
