Between 500 and 4000 eggs can be laid by the female at any one time, generally in deep water. Egg masses are usually found close to floating vegetation and hatch within days of being deposited. [2] Tadpoles remain in the larval stage for approximately one year before metamorphosing into froglets. Maturity is reached in a year for males, and two ...
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 microhylids of New Guinea and Australia completely bypass the tadpole stage, with direct development from egg to frog. The arboreal species can therefore lay the eggs within the trees, and never need venture to the ground. Where species do have tadpoles, these almost always lack the teeth or horny beaks typical of the tadpoles of other ...
They stay buried in the soil for 8–10 months a year and eat enough in one meal to last them a whole year. Couch's spadefoot toads' tadpoles transform into frogs in 7–8 days [17] Eastern spadefoot toad Scaphiopus holbrookii: Eastern spadefoot toads are found all along the East Coast of United States, from southern New England to Florida.
"Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets."
(b) Female with tadpoles removed from the oviduct. (c) Adult male calling by a stream; two tadpoles visible within the circle; (d) dorsal and ventral views of tadpoles released by a female at the moment of capture. Limnonectes larvaepartus is a species of fanged frog in the family Dicroglossidae endemic to northern and western Sulawesi ...

A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
