After being deposited on a substrate, the 8,000-35,000 eggs swell to about 3mm and hatch in about 3-4 days. Their first food source is jelly of the eggs, but the tadpoles then transition to eating algae, and finally will eat both vegetation and other tadpoles (both their own species and other species). The duration of the tadpole stage is dependent upon available nutrients, and can range from just over 2 weeks to 6 months. The tadpole attains a length of 1-3 cm, with its tail in equal length to its body. It is advantageous for tadpoles to develop quickly, as watering holes can dry up –resulting in the death of any tadpoles. Warm water temperatures result in more rapid tadpole growth and maturation. The typical tadpole begins maturation (sprouting first back legs, then front legs, and attaining a slightly greenish color) around 1-2 months of age and is then known as a metamorph.
Of a clutch of 8,000 eggs, between 20-800 of them will survive to the metamorph stage
Within several days, the little toads will begin migrating away from the pond, likely in part due to the high competition for prey that results from the high concentration of toadlets, but also to escape the adult toads who camp near the watering holes and will eat the smaller toads. The toadlets will not return to the breeding site until they are sexually mature, which generally occurs within 1-2 years, depending upon conditions and the climate. A toad generally reaches sexual maturity between 75-100 mm, and with sexual maturity are more brown to black in color. The toad may live around 10 years. The most growth occurs during the annual wet season, with toads growing about 2.5 cm/year after the second year until attaining full size. Adults often attain lengths of 10-15 cm, with females being larger than males.
