If you've ever watched a tadpole become a frog, you know it is an amazing feat of science. This lesson will examine the stages that take place from egg to an adult frog, and will explore the weird ...
That's because some sources will include only the stages of frog eggs, tadpoles, and adult frogs while others will include tadpoles with front legs, tadpoles with hind legs, and froglets in their description of the life cycle of a frog. The four main stages of a frog's life are generally held to be eggs, tadpole, froglet, and adulthood.
Tadpoles go through different stages of growth and development to become a frog. The tadpole life cycle is called metamorphosis. Egg Stage Frog Spawn. Most species of frogs will lay their eggs in water usually in spring (some species lay eggs on land).
A tadpole (also called a pollywog) is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial. When first hatched from the egg they have a more or less globular body, a laterally compressed tail and internal or external gills.
They go through several stages of life before they become adult frogs and during those stages, they live only in water. Stage 1: Egg. A frog begins life as a fertilized egg. A female frog lays a lot of eggs at one time in a pond. The eggs float on water in a jelly mass or cluster. The eggs will soon hatch into tadpoles! Stage 2: Tadpole
The developmental stages of most frogs are the egg stage, various tadpole stages, the froglet stage and the adult frog stage. The complete growth cycle of the frog generally takes between 12 and 16 weeks.
A tadpole and polliwog is the same thing but in different stages of life. Asked in Animal Life Do all animals with 3 stages of life young and parents look alike ?
Gosner stage refers to a generalized system describing stages of embryonal and larval development in anurans (frogs and toads). The Gosner system includes 46 numbered stages, from fertilized embryo (stage 1) to the completion of metamorphosis (stage 46). It was introduced by Kenneth Gosner in 1960. The system is widely used in herpetology to describe exotrophic tadpoles.

The life cycle of a frog, known as metamorphosis, is the transition of a tadpole to an adult frog.The life cycle starts with an egg, which hatches into a tadpole, the tadpole eventually gains hind and front legs, turns into a froglet as it begins to leave the water, then eventually turning into an adult frog.
