Along the Kona coast, there are several ponds a little way inshore. These are anchialine ponds containing a mix of freshwater and saltwater. The freshwater comes from a mix of rain, runoff, and the occasional spring. The saltwater intrudes from cracks in the lava.
These ponds often harbor a mix of wildlife from birds and bugs to the tiny fish in this photo. I’m not sure what these fish are, in one such pond at Kaloko-Honokohau National Historical Park, but the ponds offer a relatively safe place to start out life. However, they will need to make their way to the sea before they grow too big to escape the pond. Once there, survival will become a chancier thing.
