Quite a few years ago I was walking in shallow water along a beach in Baja california, Gulf side, looking for crabs and encountered a considerable party of sting rays swimming around, some came pretty close apparently to inspect my feet but not agressively. At low tide shallow depressions could be seen on the beach slope. I never quite figured out what was going on, feeding, mating, or what else. Has anybody got a clue?
