a spiny turban shell that snaps its trapdoor shut when threatened

A turban-shaped sea snail with spiny shell projections, sealing itself shut with a trapdoor operculum when threatened. Grilled whole in the shell, it steams in its own juices, its briny aroma and crunch standing out, in season spring through summer.

What it's made of

A turban-shaped sea snail with spiny shell projections, sealing itself shut with a trapdoor operculum at the mouth of the shell. Grilled whole, it steams in its own juices, its briny aroma and firm crunch standing out; raw, the liver carries a faint bitterness that plays against the flesh's sweetness. Grilling is said to concentrate that broth inside the shell, pushing the brine even further than eating it raw.

How it's made

Often hand-gathered one by one by ama divers or free-divers searching the gaps in rocky reefs. Many areas close the fishery from early to late summer, when it spawns, and some also set a minimum shell size to leave smaller individuals in the water. Since it feeds mainly on seaweed, the condition of the reef's weed beds is said to shape how well it fills out.

Why it took this shape

Rocky reefs like those off Shima, worked for generations by ama divers, are said to favor snails with hard, spiny shells for warding off predators. One account holds that spines grow more pronounced where wave action is stronger, tying the shell's shape to the coastline itself.
