They appear like mirages in the dark of winter, burst into full-throated glory in Spring and fade away with the summer sun. Vernal ponds remind me of Brigadoon, the Scottish village in the classic musical that comes to life for one day every hundred years. The first time I came upon a gleaming pond in a field that had been dry just weeks before, I was as stunned as if a bag-pipe-playing Highlander had suddenly materialized.
The purple sea urchin I’m holding doesn’t look like an environmental terrorist—more like a domed pincushion bristling with needle-sharp spikes. I can’t look this echinoderm (pronounced ee-KINE-o-derm), a cousin of sea stars and sea cucumbers, in the eye. It doesn’t have any. Nor does it have a brain, heart, backbone, or blood. Yet urchins, among the most ancient animals, date back 450 million years and inhabit every ocean on earth.
During my Pennsylvania childhood, the seasons paraded through the years in lockstep formation: Spring’s promises and petals. Summer’s lush ripeness. Autumn’s harlequin leaves. Winter’s icy grip. Here on the Northern California coast, the indomitable wind and waves have created seasons of their own: Upwelling (March through July), Relaxation (late summer through October), and Storm (November through February).
