Land-shellfish character

贆 names land-dwelling shellfish in an old Chinese glossary. It is a narrow historical label, not a general word for seafood.

The Erya, an early Chinese glossary, records 贆 in its section on fish: it labels shellfish living on land 贆, in contrast with water-dwelling 蜬. This is a specific natural-history distinction.

A Tang-era witness appears in the Kaicheng Stone Classics, a collection of classical texts carved into stone. Song, Ming, and Qing dictionary forms preserve the same narrow gloss.

Should I send 贆 on its own?

Use it to discuss the character, not as a ready-made reaction.

If it appears in a message, add a short gloss: the historical definition is specific enough that the glyph alone may leave your intent unclear.
