a The raw species counts from CITES trade database, LEMIS and detected on the top reptile selling website (all keywords). b Trend in number of species detected on the most species-rich reptile trading website. Solid lollipops show residuals from a linear relationship between the number of pages available in a year and the number of species detected using all keywords. Light coloured lollipops show the residual species counts each year detected by only scientific names. c The number of species detected on the most species-rich reptile trading website unique to each year in the online trade. The red line shows the unique species detected using all keywords, while the blue line shows the species detected by scientific name only. d The number of species detected on the most species-rich reptile trading website listed in any CITES appendix in that year. Whether a species was included in a CITES appendix was determined by exact matching of Reptile Database name with CITES listed name.
