They are Triassic superstars. Just amazing critters. So jealous for the Yankees that can see them along the seashore during mating season.
I stupidly didn’t take a good picture the year I saw so many they looked like the beach was cobblestoned, but the eggs are SUPER cool. The whole sand changes color, there’s so many.
