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.
Trap-jaw ants (O. haematodus) prey on the semi-terrestrial tadpoles of the rock frog T. taophora. These ants have enlarged mandibles that can quickly strike a prey to immobilize them. This causes the tadpole to be unable to move away and ultimately die at the hands of this insect.
Eggs hatch in 2 to 4 days, [7] and the tadpole development and metamorphosis is complete within 4 to 8 weeks, depending upon temperature, food quality, and food quantity. Developing rapidly helps Great Basin spadefoots avoid desiccation and consequent death in their arid environment.

American spadefoot toads have a unique diet. The adults' and tadpoles' diets vary. The adults' diet consists of invertebrates. [9] They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. [10] The tadpoles' diet is related to its surroundings and food supply.
Tadpoles are highly vulnerable to being eaten by fish, newts, predatory diving beetles, and birds, particularly water birds, such as storks and herons and domestic ducks. Some tadpoles, including those of the cane toad (Rhinella marina), are poisonous. The tadpole stage may be as short as a week in explosive breeders or it may last through one ...
The adults of this species is primarily fossorial for most of the year, but terrestrial during warm, wet periods. It only enters the water for breeding when nocturnal temperatures are at their yearly maximums and within 2–3 days of rain. [6] The tadpoles hatch from eggs after 2 days and metamorphose within 2 weeks.
Tadpoles in genus Edalorhina, which is the genus of the Perez’s snouted frog, are generally similar to most tadpoles of closely related taxa, but they have a distinct terminal oral discs. The existence of a dextral vent tube is a common trait for the clade consisting of Edalorhina, Engystomops , and Physalaemus .
