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.
Tadpoles grown in sibling groups metamorphosed faster than those that were kept in mixed groups. [4] Tadpoles have been shown to be able to recognize kin. [5] The 96h LC50 of commercial grade malathion for the tadpoles is 7.5 mg/L and sublethal levels of exposure can impair swimming. [6]
Triops longicaudatus (commonly called American tadpole shrimp or longtail tadpole shrimp) is a freshwater crustacean of the order Notostraca, resembling a miniature horseshoe crab. It is characterized by an elongated, segmented body, a flattened shield-like brownish carapace covering two thirds of the thorax, and two long filaments on the abdomen.
The tadpole madtom has a dark brown back with a lighter brown color on their sides and a yellow or white stomach. The pelvic and pectoral fins of adults are heavily covered in melanophores responsible for pigmentation, and the dorsal and anal fins contain fewer melanophores. There are also bands of melanophores on both the upper and lower jaws ...
They lack beak-like mandibles and the specialized labial tooth generally associated with most tadpoles. The newly transformed toads range from 7–12 mm (0.3-0.5 in) in body length. They are found to share the same habitat as adults, and the older stages of the tadpoles are also toxic to many predators. The males reach sexual maturity in a year ...
Due to their high levels of activity, squirrel tree frogs tadpoles are vulnerable to predation by multiple species of fish, and the adults are vulnerable to predation by the non-native Cuban tree frog. [15] [16] Because of their rapid growth and development, the tadpoles are more likely to survive insect predators than fish predators. [13]

Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. [2] Its name refers to the very large—up to 27 cm (11 in) long—tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length.
