A rococo is a large toad as you would expect with such spectacular name! It has been classified as Rhinella schneideri and it is also known as cururú toad in other parts of South America. In English it goes under the much less spectacular name of Schneider’s toad.
As toads go, a rococo is a large one: the males can measure between 15-17cm and the females between 18-25cm with a maximum weight of 2kg of weight! Pretty sizable if you ask me.
Rhinella schneideri 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.They are found in Argentina, Paraguay, Uruguay, Bolivia, and Brazil where they are sometimes kept as pets. I remember my aunt in Salto, Uruguay that used to have one in her garden that would come every evening from the cover of the plants to get its mince meat!
Luckily, at Salta, although we are at about 1,500 m above sea level we do get rococos and we see them sometimes around the house, feeding on the insects attracted to the outside lights. They are fierce predators feeding not only on invertebrates but they have been seen feeding on rodents, snakes, small birds and even fish and other amphibians.
Despite this, it a a shy animal that itself falls prey to snakes and birds of prey. In fact, just a few days ago we saw a roadside hawk (Rupornis magnirostris) catching one on the road but our approach by car scared the bird that -luckily for the toad- dropped it unharmed (as we stopped to check it). They are able to pump themselves up to avoid being swallowed by snakes but this is clearly no defense against birds.
They are mainly nocturnal and very imposing creatures with a rather large body but rather weak hind legs that makes rather slow. They are distinguished by their supraorbital crests and their pupils are large and slit-shaped. Apart from their size they also have tibial glands located in their hind legs that secrete a milky bufotoxin. The later causes nausea, vomiting, and even paralysis and death in potential predators.
Luckily, they are not threatened despite being collected for the pet trade.
