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.

Polly resembles a real-life tadpole, albeit she has arms instead of legs and is more globular in appearance. Unlike the other amphibians, she has a blue tongue rather than green. She also sports dark purple irises. She often moves in a wooden bucket filled with water and held together by a cylindrical steel frame.

2025年1月16日 · Amphibian - Larvae, Metamorphosis, Adaptations: Amphibian larvae (called tadpoles for frogs and toads) have a free-living existence while completing embryonic development and growth. The larvae transform from embryo to juvenile by the process of metamorphosis. Heterochrony is also a feature in amphibian evolution, particularly in …

Most frogs and other amphibians hatch as fish-like larvae called tadpoles, or "pollywogs." Tadpoles exist to eat and grow. They eventually transform into froglets, a process called metamorphosis. These soft globs of flesh provide tasty morsels for …

Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity, and presents a standardized terminology and an exhaustive literature review of tadpole biology.

The semiterrestrial tadpoles of the South American family Cycloramphidae remain poorly studied. In this work, we perform a comparative analysis of the external and internal morphology of these larvae, we comment on the systematic and evolutionary implications for the family, and finally, we discuss the convergent evolution of semiterrestrial ...

Tadpoles with modified colors and shapes perform better in a predatory encounter, but we suggest that this is just a minor indication of the potential fitness of these individuals. We need to know something about the breeding adults that are derived from tadpoles that respond differently to inducible stimuli.

2022年12月28日 · Amazonian lowland rainforests epitomize, as few other biomes, the terrestrial and freshwater biological diversity of our planet. We provide here a comprehensive description of the larval anurans of Central Amazonia, and their natural history.

2021年6月15日 · We studied the external, buccopharyngeal, and musculoskeletal morphology of semiterrestrial tadpoles of 14 species of Cycloramphidae. These tadpoles are highly modified and present several...

2021年1月1日 · We found tadpoles from 15 anuran species, of which five represent new records for the park. Many species showed variations in morphological characters when compared with descriptions available in...
