Actually, I *think* that central american C. gracilis are darker than the ones from Florida, which are lighter colored. Central american C. gracilis are also often mis-IDed, just like mine (which are darker), as they were labeled C. limbiatus because this species has a really dark phase.carpe scorpio said:To my knowledge, the species is the same in all respects other than toxicity. The geographical range of Gracilis is very large, Texas to Cuba and S.America, as well as several locations around the world that have had it introduced.
