The tadpoles require a permanent water habitat for at least two years while they develop. This is because tadpoles can die from a lack of moisture, especially dry summers. The frog has been noted at elevations of between about 1,214 and 7,546 feet (370 and 2,300 m) in Southern California. [1]
On average, they grow up to 1.5 to 3.5 inches (3.8 to 8.9 cm) long and females tend to be larger than males. [ 4 ] [ failed verification ] [ 6 ] [ failed verification ] The frogs lack vocal sacs, however, they can still vocalize by making a clicking sound both in and out of the water. [ 7 ]
Tadpoles emerge in as little as 15 hours. After hatching, the tadpole's only chance for survival is to develop into a toad before the puddle dries up, which takes 12 to 13 days. This is the fastest metamorphosis known for any frog or toad. Reproduction: the breeding of laying eggs normally occur from late winter to the end of March.
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 ...

Metamorphs (recently metamorphosed tadpoles) are highly pigmented like tadpoles, and quite small, usually 9–14 millimetres or 0.35–0.55 inches SVL. [ 7 ] [ 8 ] Juveniles (1+ years in age) reach sexual maturity after 3–5 years (males) or 4–6 years (females), at which time sex-specific colors and patterns emerge.
Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million ...
