Tadpole Information

The tadpole undergoes a cycle called metamorphosis

Name: Tadpole
Scientific Name: Pollywog
Stage: Aquatic Larval Stage
Category: Amphibian




Tadpoles have a chubby body and a long flat tail. It does not look similar to its adult form, a frog. They have tooth-like rasps which are used to scrape algae from the underside of aquatic plants and rocks. Like a fish, it is able to breathe through its gills and swim freely. Due to adaptation, they have a stream-lined body which enables them to glide in the water and they also have a long flat tail to help them swim. They also have gill and fin adaptations that allow breathing and movement in an aquatic environment.

Tadpoles live in lakes, ponds, creeks and streams. These habitats are the result of rainfall and are nutrient-rich habitats for tadpoles. As a tadpole grows, it metamorphosizes by gradually growing limbs, followed by the arms and finally, outwardly absorbing its tail by apoptosis.

The tadpoles were found in the KRB school pond with the required living conditions.
