(Pisaster ochraceus) are spreading across the low intertidal again this week, from Alki to Port Orchard, their brick-red bodies exposed in numbers on the extreme low tides of late June. For nearly a decade after sea star wasting disease swept through in 2013, they vanished almost entirely from these shores. Seeing them at so many sites now—over two hundred confirmed this past week—is slow recovery made tangible, a return to the ecological baseline that makes the difference between a thriving intertidal and one that has collapsed into monoculture.

Their recovery matters because sea stars are keystone predators. Ecologist Robert Paine showed that without them, mussels overwhelm the rock face, crowding out the intricate community of smaller herbivores, filter-feeders, and grazers that once gave intertidal pools their visual and ecological richness. These starfish don't just live here—they architect the entire system. Watching them return is watching an ecosystem remembering how to sustain itself.
