Observed presence of two distinct waves of developing oocytes in a study indicates a group-synchronous ovary in this species, thus, subsequent spawning during the same breeding season may occur though unverifiable in the same study (Ref. 57432).北美洲: 美國從喬治亞州的賽凡那河流域到 Ocklockonee 河流域，佛羅里達與喬治亞州; 在佛羅里達半島各處。
