In which season do tadpoles appear? What is the order in which tadpoles grow?

Tadpoles are the larvae of frogs and toads, also known as toad eggs. They are generally divided into the early, early, middle and late stages. Tadpoles have different nutritional needs in each stage and mainly live in groups. Today's article mainly introduces what season tadpoles are born, what is the order of tadpoles' growth, and why tadpoles cannibalize their own kind.

When are tadpoles born?

Tadpoles only appear in spring and summer. Tadpoles are the larvae of frogs and toads, also known as toad eggs. Newly hatched tadpoles have a spindle-shaped body, no limbs, mouths, or internal gills, and have a long flat tail. There are branched external gills on both sides of the head, which are attached to water plants. The optimum temperature for tadpole cultivation is 23-25℃, and the suitable pH is between 6-8. Tadpoles grow slowly. It takes about 60-80 days for tadpoles to metamorphose into young frogs. It is generally divided into the initial, early, middle, and late stages. The nutritional needs of tadpoles in each stage are different.

What is the order in which tadpoles grow?

The order of tadpole growth is: egg, tadpole, hind limbs, forelimbs, froglet, adult frog. The details are as follows: tadpole hatches; the base of the tadpole's tail begins to swell, the external gills disappear, hind limbs grow, and 5 toes differentiate at the end; the tadpole grows forelimbs, which are similar to the hind limbs, but the hind limbs are stronger, and the tail has not fallen off; the tail is almost gone, similar to the frog, the body is dark green and smaller; the tadpole turns into a frog.

Tadpoles (English: tadpole), written as "Kedou" in ancient times, are the larvae of amphibians such as frogs, toads, salamanders, and newts, also known as toad eggs. Newly hatched tadpoles have a spindle-shaped body, no limbs, mouths, or internal gills, and have a long flat tail. They have branched external gills on both sides of their heads. They cling to aquatic plants and rely on the remaining yolk in their bodies for nutrition. They mainly live in groups. When tadpoles mature, they begin to shed their bodies, gradually grow limbs, and then (for frogs and toads) their tails gradually degenerate through apoptosis (controlled cell death).

Why do tadpoles eat each other?

Tadpoles eat their own kind because they can't find food. There isn't enough food for so many tadpoles to eat, so they eat their own kind to survive. Tadpoles are the larvae of frogs and toads, also known as toad eggs. Newly hatched tadpoles have a spindle-shaped body, no limbs, mouths, or internal gills, and have a long flat tail. There are branched external gills on both sides of the head. They cling to water plants and rely on the remaining yolk in their bodies for nutrition.
