[1][2][3] It is one of three rather similar species sometimes referred to as "cururu toads" in Brazil, the others being R. jimi and R. marina (cane toad).

Like those, R. diptycha is a large toad, females up to 25 cm (9.8 in) in snout–to–vent length and males up to 18 cm (7.1 in).

[3] Rhinella diptycha is a widespread and very common species that occurs in a variety of habitats but most commonly in open and urban ones.

It breeds in permanent and temporary ponds, preferring ones without much vegetation.

[1] Its natural habitats include dry savanna, freshwater marshes, and intermittent freshwater marshes.
