Detailed explanation-1: -Compared with the larvae of salamanders, tadpoles have short oval bodies with broad tails, small mouths, and no external gills. The internal gills are concealed by a covering known as an operculum. Tadpoles undergo a visually striking metamorphosis before they achieve adulthood.
Detailed explanation-2: -Tadpoles have a tail and fin-like structures as well as gills, so they can breathe underwater.
Detailed explanation-3: -After another few weeks the tadpole develops front legs and the head shape of a frog. The final change occurs as the tail becomes reabsorbed by the tadpole and utilised as a source of protein. This is when the tadpole ceases to be a tadpole and becomes a tiny frog, often referred to as a froglet.
