We report the first karyological analysis of the rare American green sturgeon Acipenser medirostris. We found a mean chromosome number of 249 ± 8 (range, 234–263) with both between‐ and within‐animal variation in chromosome number. Approximately one half of the karyotype comprises very small microchromosomes and the majority of the macrochromosomes are metacentric and submetacentric.
