Tuna crabs came on shore in San Diego by the millions. Heermann’s gulls gorged on the Tuna Crabs. Kids dug pits in the sand & filled sand pails with sea water trying to save them from dying. The beach was red with crabs & green with seaweed & eel grass. According to scientists this is an indication of El Nino condition and predicts a heavy rainy season in San Diego, which we sorely need. Tuna Crabs are also knows as Squat Lobsters or Red Pelagic Crabs.
