名詞 定義　
pelvic fin The paired fin which is located posterior, ventral or anterior to the pectoral fins (abdominal, thoracic or jugular in position). Also called ischiopterygium. It functions to steer, brake and propel the fish and acts as a keel. In the pelvic fin ray count usually all the rays are counted except a small ray preceding the first ray and usually bound so closely to it so as to require dissection to be seen. In some fishes with reduced pelvics, the spine and the first ray may be bound together by a membrane and appear as one; both are counted, e.g. in Cottidae. Abbreviated as P2, P2 or V. 　
臀鰭 位於胸鰭後面、腹面或前面的一對鰭(腹位、胸位或喉位)，也稱作「 ischiopterygium 」。它的功能在於掌舵、煞車和推進魚體以及翻轉。在腹鰭鰭條的計算上，除了第一鰭條之前的一個小鰭條以外，通常所有的鰭條是全被計算的，因為它與第一鰭條非常地接近，需要解剖才能見到。在某些魚上具有退化的腹鰭，硬棘和第一鰭條經由一個膜而靠的非常地近，看起來像是同一根，而這兩者都要被計算，例如在杜父魚。縮寫當 P2 或 V。
