It is nearly impossible to tell what type of frog a tadpole will turn into. There are nearly 4,000 species of frog in the world, so the best course of action would be to narrow down what species of frog are native to the particular area you are resident in. Tadpoles live in the water and breathe with gills, and are similar in the way they swim to fish. Lungs will develop towards the onset of adulthood and the mouth will expand to become the same width as the head. Tadpoles are easy to keep and the most important thing they require is fresh, clean water at all times. They should be kept in fishbowl or a decent sized secure plastic container. Tadpoles should be fed boiled, drained, and frozen lettuce that is chopped into small chunks, the size of ice cubes. The tadpoles should not be overfed as this can dirty the water. The time it takes for a frog to develop from a tadpole can vary between 8 and 12 weeks depending on the species, the temperature of the water and the general environment. When the tadpoles start to develop small legs, a means of them getting out of the water should be provided. This could be made using small stones or branches. This is because most frogs live on the ground and will need assistance to get out of the water once they are no longer tadpoles. Once they become frogs, some will only have three legs. This is because it is common for dragonfly nymph to eat one of the stubs at the rear, during the tadpole stage. Some frogs can also be born with more than four legs, if a parasitic flatworm, which rearranges the limb bud cells of the tadpole, has infected them.
