Agnatha (class) (Vertebrata (subphylum), Chordata (phylum), ... Living Organisms (hierarchy name)) |
|
Note: Class of vertebrates representing numerous primitive, fish-like, jawless animals, such as lampreys, hagfishes, and some extinct groups. Some classifications list Agnatha as a superclass with lampreys and hagfishes as classes. Jawless fishes probably arose from ancient small, softbodied filter-feeding organisms. |

Additional Notes: |
|
Chinese (traditional) ..... 原始、狀似魚類且無頜的脊椎動物綱,包括七鰓鰻、盲鰻、以及某些已絕種的生物群。某些分類法將無頜綱列為總綱,而將七鰓鰻與盲鰻列為綱。無頜魚類可能由古代的小型軟體濾食有機體演變而來。 |
