The ốc bàn ủi, literally “iron board snail,” is a unique and rare delicacy found in the waters around Phu Quy Island. Its name comes from its distinctive shape, which resembles the flat, wide base of a traditional iron. This species can only be harvested by experienced local divers who dive deep into coastal reefs to collect them.
The snail’s meat is sweet, fragrant, and pleasantly chewy, with a rich, buttery liver. Because of its natural flavor, ốc bàn ủi is best enjoyed steamed with lemongrass or grilled over charcoal, allowing its freshness to shine.
Scientifically known as Strombus latissimus, this species belongs to the Strombidae family (the same family as red conch, white conch, and spotted conch). Although the snail itself is delicious, it is not widely consumed because the edible portion is small and the shell is extremely thick and heavy.
However, this large and beautifully patterned shell gives it high value in the seashell craft and decorative market. Many artisans use the shells to create ornaments and handicrafts.
Appearance and Habitat
The shell of the ốc bàn ủi is exceptionally thick, solid, and heavy, with bold natural patterns. Its outer lip flares wide and thick, covering half of the shell’s apex—another reason for its “iron board” nickname.
This species lives on rock–sand seabeds or coral reefs in warm tropical waters at depths of 4 to 20 meters. It is distributed across the Indo–West Pacific, from southern Japan to eastern Melanesia.
In Vietnam, the ốc bàn ủi is found almost exclusively in central coastal regions, and only rarely—making it a special treat for adventurous seafood lovers visiting Phu Quy Island.
