If anyone is going to Death Valley in the next couple of weeks, be SURE to go to Salt Creek to see the pupfish. Some years, there are not that many if the creek is low or has dried up.
This past week, there was abundant water and huge numbers of pupfish. They were very active. You'll see the males (blue) being very aggressive. You will also see birds "fishing" in the creek. For a gourmet treat, nibble on the pickleweed that grows along the creek and thrives on water saltier than the ocean.
Several species of Cyprinodon (pupfish) exist only in the Death Valley area. These species evolved after the large inland sea dried up and isolated them in scattered locations, where they adapted to the local temperatures, salinity, and plant life. They are small fish, about pinkie finger size, and a unique, exciting sight to see in the desert.
