. "Xyrichtys is a genus of wrasses native to the Atlantic, Indian and Pacific Oceans, where they are found in sandy-bottomed habitats. They are commonly known as razorfishes, as they are very laterally compressed with a sharp bony ridge at the front of their heads. This adaptation allows them to burrow very quickly into the sand at any sign of danger."@en . "* Hemipteronotus (Lac\u00E9p\u00E8de, 1801) (officially ruled to not be available)" . "Xyrichtys"@en .
