As a generalized system, Gosner stages may not be adequate for describing development of some anuran tadpoles. [3] For example, in the torrent-dwelling tadpoles of Ansonia longidigita and Meristogenys orphnocnemis , the usual Gosner stages become inappropriate beyond the stage 41 because the tadpoles retain their oral disc longer than the ...
These new predators can increase predation, decrease tadpole survival, and thus diminish the frogs' numbers. [20] The introduction of the American red swamp crayfish, Procambarus clarkii, is an example of how invasive species can impact parsley frog behavior and life. Pelodytes punctatus tadpoles have relatively high plasticity, [20] as ...
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.
The adult frogs of P. paradoxa have a snout–to–vent length of 3.4–7.6 cm (1.3–3.0 in) and are green to brown coloured with dark green, olive or dark brownish stripes or mottling; the pattern and hue varies significantly. [4] [8] The female of P. paradoxa lay eggs among water plants; the eggs develop into tadpoles. They always reach a ...
The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds.

The quite muscular tadpoles are carnivorous and feature several rows of horned teeth. Adults feed on slugs , myriapods , spiders , beetles , and grasshoppers . The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [ 5 ]
A tadpole person [1] [2] [3] or headfooter [4] [5] is a simplistic representation of a human being as a figure without a torso, with arms and legs attached to the head. Tadpole people appear in young children's drawings before they learn to draw torsos and move on to more realistic depictions such as stick figures .
American spadefoot toads have a unique diet. The adults' and tadpoles' diets vary. The adults' diet consists of invertebrates. [9] They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. [10] The tadpoles' diet is related to its surroundings and food supply.
