Most Ceratophrys species if male will begin to call at around 4.5 to 5.5 months of age and are around 2.5" to 3" SVL(snout to vent length). This does differ from species to species and depending on your frogs growth rate as well as the amount of food and nutrition your frog had at the crutial growth stages of its life.

Croaking or calling is a definite male. A lot of males have very dark spots on their vocal sack that do not fase with age, but that is not always a keen way to determine male. The white spots are nothing. Males when reaching sexual maturity will produce what is call ed nuptual pads on the thumb of each hand which are a dark spot that resembles a mole. They do not reach sexual maturity until 8 monthe to a year of age.

Snout shape and bluntness is not entirely accurate either and only appears in certain species. For instance C. Cranwelli Males do not have a blunt face and facial features are not much different than the female of the species. Size can be a good determination sometimes in mature frogs as the male of Ceratophrys species are smaller than the females.

Pics will help plus we really love to see photos of everyones frogs on here.
