Gestation length varies with reproductive strategy across species, so comparing how long pregnancies last helps you understand expected litter size and breeding frequency. The eastern cottontail, a rabbit, has a very short gestation—roughly a month—allowing multiple litters in a favorable season. The gray fox, a small canid, undergoes a significantly longer gestation, typically around seven to nine weeks, which generally means fewer litters per year. So, in standard biological data, the gray fox has a longer gestation than the eastern cottontail. If a study key states otherwise, it may reflect a different data source or an error in the key; the overall pattern remains that gray fox gestation is longer.
