Like beautiful butterflies, frogs and toads undergo an astonishing transformation – which is called ‘metamorphosis’ – as they grow up. From jelly-like eggs laid in water, they grow into wriggling tadpoles, and finally grow legs suitable for land!

What are the stages of a life cycle of a frog?

The Frog Life Cycle Frogs are a type of amphibian, so they start off as eggs and go through four stages in their life cycle, becoming five different things in the process: eggs, tadpoles, tadpoles with legs, froglets, and adult frogs.

What is the metamorphosis of a frog?

Frog metamorphosis involves a fish-like organism that has gills and a tail transforming to a semi-aquatic frog. Frogs start as eggs which hatch and grow into tadpoles. At around four weeks, tadpoles lose their gills and rely on lungs for respiration. By six to nine weeks, hind limbs appear and then forelimbs.

Does a frog go through complete metamorphosis?

A frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. There are three life cycle stages in incomplete metamorphosis (egg, nymph, adult) while there are four stages in incomplete metamorphosis (egg, larva, pupa, adult).

What are the 3 stages of metamorphosis?

Both complete and incomplete metamorphosis extend from the egg stage to the adult stage. Complete metamorphosis consists of four stages: egg, larva, pupa, and adult. However, the incomplete metamorphosis consists of three stages: egg, nymph, and adult.

Why do frogs undergo metamorphosis?

Metamorphosis is a vital part of evolutionary history of amphibians in which their fishlike, gill-breathing larvae turn into lung-breathing terrestrial amphibians. Metamorphosis also means to get the optimum out of both worlds, water and land, which definitely leaves amphibians with an evolutionary advantage.

Does a caterpillar go through metamorphosis?

What is the second stage of a frog life cycle?

The second stage in a frog’s life cycle is becoming a tadpole. A tadpole is a very small creature with gills, a tail and a mouth. The tadpole swims in and eats algae from the top of the water. As the tadpole grows it will develop teeth and skin over its gills.

Do frogs go through complete metamorphosis?

What is the life cycle of a frog called?

Life Cycle of a Frog | Earth Rangers: Where kids go to save animals! The process in which a tadpole turns into a frog is called metamorphosis, and it is an amazing transformation. Here we have broken metamorphosis down so you can see the stages a tadpole goes through as it develops into an adult.

How many stages of metamorphosis in a frog’s life?

Learn the four stages of metamorphosis in a frog’s life with the Life Cycle of a Frog Worksheet. Frogs are amphibians, which means that they can live in water or on land. They go through several stages of life before they become adult frogs and during those stages, they live only in water.

What happens when a tadpole turns into a frog?

When the tadpole reaches the froglet stage, it is almost a full adult. At this point, the tadpole’s gills have disappeared, and its lungs have enlarged. This means it is ready to leave the water and live on land. Once its tail disappears, it will become an adult frog. This is a fully grown frog.

What happens to a frog when it leaves the water?
