Tadpole of A. americanus. The American toad lays between 2,000-20,000 eggs in two strings which hatch in 3-12 days. [7] The hatched tadpoles, while very small, are recognizable by their skinny tails in relation to the size of their round black bodies. They reach adulthood in 50–65 days.
The breeding season is from late winter to early spring. [4] Eggs are laid in a foamy nest and tadpoles can take 8–12 months to develop. Pale brown, they can be up to 6.5 cm long.
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial.

The eggs hatch and the tadpoles take 30 to 55 days to develop before undergoing metamorphosis into juvenile toads about 1 cm (0.4 in) long. The tadpoles feed on algae which they scrape from underwater vegetation. Adults are carnivorous and feed on any small invertebrates they can find. [6]
