noun
tapestry turban; Turbo petholatus
A species of turban shell with a distinctive patterned shell, often used in shellcraft and as a decorative item.
リュウテンサザエの殻は美しい模様で知られている。
The shell of the tapestry turban is known for its beautiful pattern.
サザエ is the common turban shell (Turbo cornutus), a different species often eaten in Japan. リュウテンサザエ is a tropical species valued for its shell rather than as food.
The name combines 竜天 (ryūten, 'dragon heaven') with 栄螺 (sazae, 'turban shell'), likely referring to the shell's ornate, dragon-like pattern. The exact origin of the name is uncertain.
