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 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.

They eat flies, crickets, caterpillars, moths, spiders, centipedes, millipedes, earthworms, and snails. [10] The tadpoles' diet is related to its surroundings and food supply. When they are first hatched, they eat plankton. [10] After a few days, they become carnivorous and eat animals. [10] Tadpoles sometimes resort to cannibalism to survive.
Frogs have a two-stage life cycle, with the aquatic tadpole larva metamorphosing into the adult form. This tadpole was in the late stages of metamorphosis. Adults of this species are a similar ...
After they hatch, the tadpoles fall into the waters below. [15] The tadpoles are elongated, with powerful tails and low fins, suited for fast-flowing water. [11] Outside of the breeding season, some species live in the canopy. The majority of amphibians use cutaneous respiration, or the process of breathing through the skin.
In the United States, around 2.3 million households are home to reptiles, including turtles. Here's what the reptile can and cannot eat.
The coverings over the eggs will remain in the wild until the brood emerges. [15] The embryos develop through to the tadpole stage inside these pockets but do not emerge as tadpoles, instead remaining in their chambers until complete development to toadlet stage. The young toads grow a tail during their growth, but these will only be temporary ...
They lay eggs, those eggs hatch into tadpoles ... and you learned the rest in science class. However, a newly discovered species of frog has upped the ante. They skip the egg stage and just give ...
