Abstract First paragraph: The family Atherinopsidae1 consists of 150 to 160 species, and most of them live in marine and brackish water. The genus Chirostoma is divided into two groups: Jordani and Arge. The Jordani group contains all of the relatively large species known as "white fish" in Mexico, while the smaller species belong to the Arge group and are known as "charales". All members of the genus are endemic to central México and live in fresh water, but they share many features with marine Atherinopsids because of their common ancestry (Barbour, 1973).
