What is polliwog frog?

The polliwog frog is a common name for the tadpole of the American bullfrog (Rana catesbeiana). Its scientific name is derived from Carl Linnaeus, who first described it as Rana temporaria. The polliwog frog is an amphibian that goes through the stages of metamorphosis from a fish-like larva to an adult frog. The tadpole has a round body, a wide tail, and a pair of front and back legs which develop as it transforms into an adult frog. It feeds on algae and organic matter in ponds and streams, and it may take up to two years to reach full adult size. The American bullfrog is a familiar and iconic species of frog in North America, and its tadpoles are commonly observed in freshwater habitats throughout its range.
