Largest genus of toads

The largest genus of toads is Bufo, the genus of true toads. It currently contains no less than 205 species out of the 355 species of toad currently known to science. Some researchers have removed certain species from this genus and housed them in others, but even in these alternative classifications Bufo remains by the far the largest genus of toads. Bufo includes many notable and famous species of toad, such as the world's largest toad (the cane toad B. marinus – although some authors now reclassify it as Rhinella marina), another exceedingly sizeable toad (Blomberg's giant toad B. blombergi), and the common toad B. bufo. A very cosmopolitan genus, its species are absent only from the poles, Madagascar, and Oceania (there are no native species in Australia either, but the cane toad has been introduced here, and has bred so extensively that it has become a major pest).
