Females usually lay their eggs in shallow, calm water that has little action around it. If they survive, embryos will hatch into tadpoles within one to three weeks. The tadpoles feed on periphyton, filamentous algae, diatoms, and pollen in or on the surface of the water. They feed using suction, and a beak-like structure that helps scrape ...
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. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails.
Chytrid fungus is known to spread at much lower rates in smaller populations, so by introducing smaller numbers of toads to these isolated locations, the chytrid effect was lowered. [16] In the Colorado project, they utilized a probiotic bath for the tadpoles called "Purple Rain" that strengthened their skin microbiome, providing resistance to ...
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]

How long it takes for breeding onset varies from 1–4 years depending on the levels of snow and temperature. Very cold temperatures may cause death of larvae. [7] The juvenile may be a tadpole for 3 to 4 years before undergoing metamorphosis. [8] However, this rate heavily varies depending on the temperature and elevation of the area. [7]
Tadpoles and eggs are vulnerable to predation from various small pond-dwelling creatures, such as leeches, fish, and some aquatic beetles. [8] A study published in 2016 in the Canadian Journal of Zoology indicated that tadpoles in warmer water develop more quickly than those in cooler climates, meant to mimic the differing environments found in ...
