QMPro 1.0 41-8688 . ...from San Jose, CA WRONG!!! The red stuff in the salt ponds is known as brine shrimp. Artemia Salina, a small shrimp which also is used for tropical fish food. They are netted and sold at your local pet shop as live food for fish. The maximum size of these shrimp is 1/2 inch or so, and they reproduce prolifically when the salt concentration gets high enough in the salt ponds. They also exist in Great Salt Lake, and I think, in Mono Lake. Dinoflagellates, I believe are an open ocean organism which are eaten by filter feeders (Clams, Mussels, Oysters) They contain a nerve toxin which is concentrated by the clams. They are mostly found when the waters warm up and are responsible for the old agage of "Don't eat shellfish during months without an "R" in them." (May, June, July, August) These are what is commonly referred to as the "Red Tide." Dick Lucas
