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.
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 ...
The wood frog has a complex lifecycle that depends on multiple habitats, damp lowlands, and adjacent woodlands. Their habitat conservation is, therefore, complex, requiring integrated, landscape-scale preservation. [1] Wood frog development in the tadpole stage is known to be negatively affected by road salt contaminating freshwater ecosystems ...
Pseudis is a genus of South American frogs (swimming frogs) in the family Hylidae. [1] They are often common and frequently heard, but easily overlooked because of their camouflage and lifestyle, living in lakes, ponds, marshes and similar waters with extensive aquatic vegetation, often sitting at the surface among plants or on floating plants, but rapidly diving if disturbed.
Most species (e.g. Blyth's river frog L. blythii or the fanged river frog L. macrodon) develop normally, with free-swimming tadpoles that eat food. [5] The tadpoles of the corrugated frog (L. laticeps) are free-swimming but endotrophic, meaning they do not eat but live on stored yolk until metamorphosis into frogs. [5]

The Secret Life of Frogs is a 2019 Indian documentary film that explores lesser-known frog species. It premiered on May 1, 2019, on Animal Planet. [1] Directed by Ajay Bedi, Vijay Bedi, and narrated by Jeff Alan Greenway, [2] the 45-minute film provides insights into the behaviors and lives of various frog species, with a particular focus on the purple frog and the torrent frog.
It is monotypic, being represented by the single species, Lithodytes lineatus, also commonly known as the gold-striped frog [1] or painted antnest frog. [3] It is found in tropical South America [4] where it lives in humid forests among the leaf litter. These frogs build foam nests at the edge of temporary pools, and the tadpoles develop within ...
