How big can a frog s tadpole grow to be a frog?

Tadpoles turn into frogs.

After the frog lays its eggs at the water's edge, after a period of time, the eggs hatch into tadpoles and feed on the algae and plankton in the water. After about a month and a half, the base of the tadpole's tail begins to swell, and after a week, hind legs grow, and then the forelimbs begin to take shape, and the tail shortens at the same time, at which point the little tadpole becomes a small frog. The frog's body is short and flat, without a neck and tail, the eyes are protruding, moist and smooth, and the hind limbs are long and strong, and they are good at jumping.

Most frogs inhabit shady, damp corners of trees and like to eat small insects.

The shorter the tail, the less time it takes.

Tadpoles turn into frogs in about 80 to 150 days.

Growth stage. Early stage of growth: (1 10d) Tadpoles do not forage for food within three days of hatching, relying on nutrients brought from egg yolk to maintain life, and early feeding will lead to their death.

Pre-growth stage: (10 20d) After 10 days, the tadpole eats more, the growth and development accelerates, the tadpole begins to look for new food, but its digestive function is still not strong, and the quality of feeding directly affects the survival rate of the tadpole.

In order to promote the development of the tadpole's digestive tract as soon as possible and adapt to the "herbivorous" biological characteristics of a specific tadpole stage of amphibians, tadpoles should be fed with plant feed and algae plants, such as duckweed, in addition to pasty bait after 20 days of age.

Late growth: (50 78 days) This period is the critical period for tadpoles to transform into young frogs, during which tadpoles develop hind and forelimbs, and transition from aquatic to amphibious.

Tadpole feeding method:

1. Tadpoles eat plankton, and it is best to use pond water to raise tadpoles, tap water is not good, and pure water is not good.

2. Tadpoles will kill each other, and when many of them are together, they will secrete some toxins to kill some individuals, so that the rest of the individuals can better survive in a limited environment.

3. The feed of tadpoles should be mainly plant food. Boiled spinach and endive are suitable feeds, but should not be overcooked and the fibre should be removed.

4. Give less feed at the initial stage, gradually increase it later, and regularly feed once a day, not too much, so as not to cause corruption in the feed residual water. Feed residues after each feeding must be removed with a straw and the water must be changed every day or two. The easiest bait is bread, biscuit crumbs or rice grains, or a small amount of cooked egg yolk can be given as animal feed.

The process of turning a tadpole into a frog takes 2-3 months.

The newly hatched tadpole has a spindle-shaped body, no limbs, mouth and inner gills, and has a long tail with flat sides, and branched outer gills on both sides of the head, which are adsorbed on aquatic plants and rely on the remaining yolk in the body to provide nutrition. Mainly living in groups. When tadpoles mature, they begin to deform and gradually grow limbs, and then (in the case of frogs and toads) gradually degenerate their tails through apoptosis (control of cell death).

It takes about 50-78 days for a small tadpole to become a frog.

Small tadpoles need to go through four stages to grow into frogs, the first stage is the early stage of growth, that is, from hatching to 10 days old, the first three days do not need to forage, after which you can feed a little egg yolk, the second stage is the early stage of growth, that is, when 10-20 days, the amount of food will increase.

The third stage is the middle stage of its growth, that is, when it is 20-50 days, some have begun to grow hind legs, and the digestive function of tadpoles continues to increase, and the fourth stage is the late stage of growth, in which tadpoles will grow hind limbs and forelimbs, and will transform into young frogs at 50-78 days.

The process of change in tadpoles

1. The newly hatched tadpole has a spindle-shaped body, without limbs, mouth and internal gills, with a long tail flattened on the sides, and branched outer gills on both sides of the head. These days, tadpoles mainly rely on the remaining yolk in their bodies for nutrition, and after a few days, when they grow out of their mouths, they can feed on microorganisms in the water.

2. After a while, the tadpole's outer gills will disappear, and the inner gills will grow, and the lateral line will gradually appear on the outside of the body, and the heart will develop into an atrium and a ventricle, which is very similar to a fish from the external form to the internal structure.

3. After about another 40 days, the tadpole will begin to change again, it will first grow hind limbs, then grow forelimbs, the tail will gradually shorten, the inner gills will disappear, the lungs will be formed, the heart will change from one atria and one ventricle to two atria and two ventricles, and its external form and internal structure will no longer resemble a fish. At this time, the tadpole has become a young frog, and the young frog will gradually develop into an adult frog when it lands out of the water.

The frog is an amphibian.

When hatched, tadpoles have no limbs and look more like fish, growing by drinking algae from the water. As it grows, the body also changes, and the gills gradually shrink, and lungs grow inside the body, so that they can breathe oxygen directly from the air.

When it reaches a certain stage of development, a small tadpole will first grow two hind legs, then a front leg, and the tail will slowly disappear, and finally become a real little frog, which will come from the water to live on land.

The frog is the mother of the tadpole! Ha ha.
