“…Ceratophrys cranwelli and Ce. ornata have been repeatedly considered "diploid-octoploid counterparts" or a "diploid-octoploid cryptic species pair" (Bogart and Wasserman, 1972;Barrio, 1980;Mercadal, 1981Mercadal, , 1986Mercadal de Barrio, 1987; Mercadal de Barrio and Barrio, 2002). However, this cannot necessarily be taken to mean that these two species are sister taxa, although this is recovered with high support in our analysis (Fig.…”

“…joazeirensis and Ce. cranwelli (Mercadal, 1986;Mercadal de Barrio and Barrio, 2002;Vieira et al, 2006), mostly their color pattern, and their distribution in semiarid areas. Our results strongly support the monophyly of Ce.…”

“…Los datos acerca de la longevidad de la especie son procedentes de su cría en cautiverio al igual que para otras especies (entre 5 y 14 años; www.pondturtle.com), dada la dificultad para relevar tales datos en campo (Gallardo, 1974;Duellman y Trueb, 1994) y al hecho de no contar hasta el momento con datos provenientes de la esqueletocronología. Otra característica llamativa es su poliploidía extrema, siendo una especie octoploide a diferencia de C. cranwelli que si bien es su especie hermana de Argentina es diploide (Mercadal de Barrio y Barrio, 2002).…”
