On the reef rocks off Dongyin, grey-brown, conical limpets and turban shells cling to the surface. Fishers brave the spray to pry them off by hand; the shells are thick and round with a pointed apex, uncannily resembling a soldier's helmet — which is why locals call them "sea helmets." Blanch in salted water, scoop out the flesh: it is springy and snappy with a deep, concentrated ocean flavor. A rare shellfish delicacy found only on Matsu's Dongyin.
What Are Sea Helmet Limpets and Turban Shells
"Sea helmet" is the Matsu local term for intertidal limpets and turban shells, named for their conical shell with a pointed apex and a thick, heavy overall form that resembles a military helmet. The main species include limpets of the Patellidae family and turban shells of the Turbinidae family, both of which attach to reef rock and feed on algae. Matsu sea helmets range from about 3–8 cm in diameter; the shell wall is thick, the apex pale grey-white. Once opened, the flesh is white or grey, firm, chewy, and distinctly flavored with a pronounced sea character.
The Matsu Daily has published feature articles introducing the ecology and culinary culture of limpets; the Juguang Township Office also lists turban shells as a local seafood specialty, with Dongyin waters as the main production area. Sea helmets are wild-foraged, scarce, and difficult to harvest; combined with the fact that local Matsu gourmands keep most for personal consumption, almost none leave the islands — they are virtually unseen on the main island of Taiwan. Prices are high, and they represent a collector's-grade Matsu seafood.

Visiting Tips
- Sea helmets are wild-foraged and supply is unreliable; when you reach Dongyin, ask the restaurant directly whether they have any that day.
- Shellfish can accumulate marine pollutants; people with shellfish allergies or pregnant women should avoid eating them.
- Do not attempt to harvest them from the reef rocks yourself — intertidal zones are slippery and dangerous, and some areas are within protected marine zones.
