U+870C "蜌" CJK Unified Ideograph-# Unicode Character

U+870C "蜌" CJK Unified Ideograph-# is a rare and largely archaic Chinese character that historically referred to a type of small aquatic shell, specifically a kind of freshwater clam or mussel. Composed of the radical for "insect" or "creature" on the left and the phonetic component "必" on the right, it appears in classical texts and ancient dictionaries, such as the "Shuowen Jiezi," but is not commonly used in modern Chinese or Japanese writing. Its precise zoological identification remains uncertain, and it is primarily of interest to scholars of historical linguistics and paleography.
