Anatomy of a wood frog tadpole (Lithobates sylvaticus) As a frog tadpole matures it gradually develops its limbs, with the back legs growing first and the front legs second. The tail is absorbed into the body using apoptosis. Lungs develop around the time as the legs start growing, and tadpoles at this stage will often swim to the surface and ...
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.
The tadpole of this species is considered unpalatable to many species that would commonly predate on tadpoles. They also exhibit behaviors to avoid predation. To avoid fish, the tadpoles will move to stream margins in order to make them inaccessible to the fish. The tadpoles will also reduce activity after sensing a fish's chemical cues. [21]
Frog appears to have been adapted from frosc as part of this trend. [11] Meanwhile, the word toad, first attested as Old English tādige, is unique to English and is likewise of uncertain etymology. [14] It is the basis for the word tadpole, first attested as Middle English taddepol, apparently meaning 'toad-head'. [15]
Tadpole 2015-04-16-12.04.26 ZS PMax (16571152244) (2) After they hatch, they remain tadpoles for two to three months before transforming into frogs and are ready to leave the water. [32] Following breeding in the spring, the spring peepers' larval stage lasts two to three months. [30] The spring peeper can live an estimated three years in the ...

The world's largest frog is the goliath frog of West Africa—it can grow to 15 inches (38 centimeters) and weigh up to 7 pounds (3.2 kilograms). One of the smallest is the Cuban tree toad, which ...
Tadpoles probably spend most of their time attached to such substrates by a large oral sucker. The large, sucker-like mouth parts of the tadpoles are a second distinctive feature of the species, enabling survival in turbulent water unsuitable for other frogs. They prefer turbulent water to smooth, swiftly flowing water. [16]
