Shireen -
Are there crayfish there?
Crayfish burrows provide refugia from dessication for a variety of animals
including: bluefin killifish, pirate perch, pygmy sunfish, tadpole madtoms,
and high densities of some invertebrates like ostracods. Aquatic animals are
believed to survive in them as long as 3-4 months.
This is a real phenomenon, but unfortunately not very well-studied.
In Florida, I would sometimes see adult golden topminnow and flagfish
miraculously appear in newly-flooded, but apparently isolated wetlands.
Now, I would look for crayfish burrows.
