English Names

Giant Toad (Schneider and Sinsch, 2004, Z. Feldherpetol., 11: 187 [as Bufo bufo spinosus]).


Iberian Peninsula and southwestern France (north to about Caen to about Lyon; an isolated population on the Isle of Jersey (United Kingdom); northwestern Africa in the northern mountains of Morocco, Algeria, and Tunisia.


Recuero, Canestrelli, Vörös, Szabó, Poyarkov, Arntzen, Crnobrnja-Isailovic, Kidov, Cogǎlniceanu, Caputo, Nascetti, and Martínez-Solano, 2012, Mol. Phylogenet. Evol., 62: 71-86, considered Bufo spinosus a species distinct from Bufo bufo, redelimited its range, noted that African populations are notably distinct from European Bufo spinosus, and suggested on the basis of molecular evidence that it is the sister taxon of Bufo bufo + Bufo verrucosissimus. Prior to this study, the status of populations in southern Europe and the eastern Mediterranean had been the source of much confusion regarding the status of Bufo spinosus. Kutrup, Yilmaz, Canakci, Belduz, and Doglio, 2006, Amphibia-Reptilia, 27: 268-273, discussed geographic variation in 16S rRNA and rejected the Turkish populations of Bufo bufo spinosus as a distinct subspecies or species, suggesting instead that it should be placed in the synonymy of Bufo bufo verrucosissimus (thereby implying that they regarded Bufo verrucosissimus as part of Bufo bufo). Barbadillo-Escrivá, 1987, Guia INCAFO Anf. Rept. Peninsula Iberica: 150-154, provided an account for the Iberian populations as Bufo bufo. Llorente, Montori, Santos, and Carretero, 1995, Atlas Amf. Rept. Catalunya Andorra: 66-68, provided an account as Bufo bufo and detailed range map for Catalunya and Andorra. Schneider and Sinsch, 2004, Z. Feldherpetol., 11: 187-201, considered Bufo spinosus to be a species distinct from Bufo bufo, although the distribution of both taxa was uncertain and Nöllert and Nöllert, 1992, Die Amph. Eur.: 286-292, noted considerable hybridization with diagnostic Bufo bufo in Portugal, central and southern France, the southern Alps and the northern part of the Balkans. Previously Bufo spinosus had been considered either a synonym or subspecies of Bufo bufo by Bonaparte, 1835, Iconograph. Fauna Ital., 2 (Fasc. 14): unnumbered; Tschudi, 1838, Classif. Batr.: 88; Duméril and Bibron, 1841, Erp. Gen., 8: 672 (as Bufo vulgaris); Boulenger, 1881 "1880", Proc. Zool. Soc. London, 1880: 545-574; Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 303. See Salvador, 1996, Smithson. Herpetol. Inform. Serv., 109, and Schneider, 1974, Salamandra, 10: 55-60, for accounts for the North African population (as Bufo bufo). Lizana, 1997, in Pleguezuelos (ed.), Dist. Biogeogr. Anf. Rep. Esp. Portugal: 152-154, provided a brief account, photograph, and detailed map for Iberia. Rivera, Escoriza, Maluquer-Margalef, Arribas, and Carranza, 2011, Amf. Rept. Catalunya: 75-77, provided a brief account for northeastern Spain and adjacent France, as Bufo bufo. Martínez-Solano and González, 2008, Biol. J. Linn. Soc., 95: 824-839, noted a relative deep genetic divergence between Iberian and North African populations of Bufo bufo (all of which are now considered Bufo spinosus). Garcia-Porta, Litvinchuk, Crochet, Romano, Geniez, Lo-Valvo, Lymberakis, and Carranza, 2012, Mol. Phylogenet. Evol., 63: 113-130, subsequently largely confirmed these results, including noting the deep divergences among the African populations and from the European populations, and regarded Bufo spinosus as a subspecies of Bufo bufoBeukema, de Pous, Donaire-Barroso, Bogaerts, Garcia-Porta, Escoriza, Arribas, El Mouden, and Carranza, 2013, Zootaxa, 3661: 41-42, provided an account for Morocco (as Bufo bufo ssp.) and without discussion discarded the evidence of Bufo spinosus being diagnosable from Bufo bufoArntzen, Recuero, Canestrelli, and Martínez-Solano, 2013, Mol. Phylogenet. Evol., 69: 1203–1208, discussed the phylogenetics and species taxonomy of this and near relatives and concluded that Bufo spinosus is a distinct species. Arntzen, McAtear, Ziermann, Ohler, van Alphen, and Martínez-Solano, 2013, Contrib. Zool., Amsterdam, 82: 147-169, reported on the contact zone of Bufo bufo and Bufo spinosus. Arntzen, Wilkinson, Butôt, and Martínez-Solano, 2014, Herpetol. J., 24: 209–216, reported on the population on Jersey, United Kingdom. Nöllert, Grosse, Buschendorf, and Geiger, 2016, Mertensiella, 24: 7–32, summarized and discussed the taxonomic history of this species and its recognition within the Bufo bufo group and provided a range map. Trujillo, Gutiérrez-Rodríguez, Arntzen, and Martínez-Solano, 2017, Contrib. Zool., Amsterdam, 86: 1–10, reported on a hybridizing population in northwestern France with Bufo bufo with no evidence of restriction to gene flow.
