U+87BA "螺" CJK Unified Ideograph-# Unicode Character
U+87BA "螺" CJK Unified Ideograph-# is a Chinese character that primarily refers to a spiral shell, such as that of a snail or conch, and by extension denotes anything coiled or helical in shape. It is commonly used in words like “螺旋” (luóxuán), meaning spiral or helix, and “海螺” (hǎiluó), meaning conch or seashell, and appears in contexts ranging from marine biology to geometry and mechanical engineering. In historical and cultural usage, this character also appears in classical texts and names, and it serves as a radical component in other complex characters related to shells or twisting forms. Its structure combines the radical for insect or creature “虫” with a phonetic component, reflecting its origins in describing living organisms with coiled shells.
