Exploring the edges where saltwater life meets human curiosity.

Not all marine magic happens in tidepools. Dock fouling is the art of laying belly-down on floating docks and peering into the murky kingdom below. Here, on pylons and plastic, sea slugs bloom among tunicates, bryozoans, and mystery membranes. This is where urban ocean life thrives—and where I’ve found some of the weirdest, rarest, and most beautiful creatures you’ll never see in a guidebook.

The coast is not a line—it’s a fractal, a memory, a living archive. This Tidepool Atlas is a guide to the places I’ve explored, from urban piers to remote surge channels, each one filled with species and surprises. Click into any site to see what lives there, when I visited, and what the slugs were doing when the tide turned.

Sea slugs don’t stay put. From dock to reef, coast to Sound, species are slipping between zones, extending their ranges, or reappearing after decades of silence. The Slug Highway is my ongoing project to track these movements—part field survey, part speculative map, part resurrection watchlist.

📍 Come see what’s on the move, what’s been reborn, and what secrets are still unshelled.

These are my psalms from the low tide line. Intertidal Gospel is a  zine, part prayer, part poem, part species invocation. It’s how I translate fieldwork into magic—where nudibranchs become saints, docks become temples, and every cerata carries a prophecy.

📖 Browse the pages, read the gospel, and believe in slugs.

Where science, wonder, and sand grit mix in equal measure. These entries are pulled straight from the dock edges and rocky tide zones of the Pacific coast. Some are species reports, others are love letters to forgotten places, and many are both.

Each post is a record of who I found, where they were hiding, and what the water felt like that day.

I’m Luan, a nudibranch naturalist, dock fouler, and low-tide science witch based in Seattle. I’ve spent years exploring the intertidal zones and floating docks of the Pacific Northwest, documenting sea slugs with a mix of photography, data, and deep curiosity.
