Cost per species for both classes. Red bars represent amphibians, while blue bars represent reptiles. The green bar represents the total cost of invasive herpetofauna. The wide, lower part of the bar represents the observed costs, while the thinner part represents the total costs (Observed plus Potential costs). Note that the y-axis is on a log10 scale. Animal silhouettes are from PhyloPic (phylopic.org).
