Body shape (shape guide): fusiform / normal; Cross section: oval.
腹鰭間的突起小而兩裂的。 泳鰾不存在。 側線逐漸地對於尾柄彎曲下來。 腸道有 2 摺層與 3 肢翼。 雄性有沒有條紋或者斑點，雌性在側邊上有二代理人成列的褐色斑點。 身體整個的被覆蓋著的小鱗片, 沒有前面的甲胄。
It is now extinct outside the Gulf of California. Supports a commercial net fishery close inshore, in estuaries and coastal marshes (Ref. 9987). Its biology is almost completely unknown. This fishery operates on a relict of the original population.
現在它是滅絕的在加州灣以外。 在河口與海岸的濕地中, 支撐一個商業的淨餘漁場近岸。 (參考文獻 9987) 它的生物學特性幾乎完全未知。 這一個漁場在最初族群的一個殘餘倖存者上操作。
