Only three organisms can survive the saline water of Mono Lake --- brine shrimp, brine flies, and green algae. I enjoyed seeing the delicate half-inch shrimp swimming in the clear water. The black area on the beach is a layer of millions of brine flies. These small flies will scatter a few inches above sand when disturbed; fortunately, they don't bother people! The California gull will enjoy the flies as a snack since there are no fish in the lake. The shrimp and fly larvae eat the algae, which begins this very limited food chain.
