Merman throat cartilage

Each merman’s body holds abundant water path dao marks, and in the throat there is a particular cartilage filled with sound path dao marks. That cartilage is why mermen, by human standards, are natural born singers and can produce beautiful singing. There was a point in history when humans slaughtered mermen to take the sound path cartilage from their throats, because it was an excellent sound path Gu material. ^{ch. 1666}
