How to Write 蛑 (móu) — Meaning “swimming crab”

Imagine a crab with a big shell that looks like a hat (牟 sounds like "moo" as in a cow, but picture the crab wearing a cowbell). The 虫 on the left reminds you it's a creature, and 牟 helps recall the sound "móu" like a crab's angry grumble.

The left side 虫 should be written narrow and tall, with the last dot placed neatly. The right side 牟 has a stroke order of left-to-right: first the top part (撇, 横, 竖, 横) then the bottom 牛 (撇, 横, 横, 竖). A common mistake is making the bottom 牛 too wide, which unbalances the character.

While 蛑 (móu) means swimming crab and uses 虫 + 牟, 蚊 (wén) means mosquito and uses 虫 + 文, and 蚋 (ruì) means a small biting fly using 虫 + 内. Visually, the right parts are distinct: 牟, 文, and 内. Their meanings are all insects/arachnids, but 蛑 specifically refers to a type of crab.

蛑 is rare in daily speech and mostly appears in classical or regional terms like 蝤蛑 (swimming crab) or 抓蛑 (to catch swimming crabs). You might see it in seafood menus or coastal dialect writing, but it is not part of standard HSK vocabulary and has a literary feel.

Common words containing 蛑 include: 蝤蛑 (qiú móu) — Swimming crab; 抓蛑 (zhuā móu) — to catch swimming crabs; 蛑壳 (móu ké) — crab shell.
