Brine Shrimp
Dozens in pools in clay. Lots of moulting skins (had thought that they were dying, but only a few were dead beasts, most were just "skins"), so must be a sizeable population.
Really Cool!!!
Zillions of mosquitoes: must have lost half a litre of blood (OK, perhaps a little less) in 15 minutes. Like a fool, took no photos, but then I was preoccupied with more exciting things.
