There are many different species and genus of anurans. Frogs eat mice, insects, other invertebrates, and other vertebrates. Tadpoles eat algae, waterplants, mosquito larvae, and carrion. Anurans catch thier food by lunging forward and grabbing the food with thier tongues. Tadpoles eat with little scraping teeth they scrape against thier food.
Anurans are amphibians which live part of thier lives in water and the other part on land.
In spring males go to ponds, puddles, and lakes. There they start calling and fighting over territory. Once they win a female she lays eggs and he fertilizes them. A little while later they hatch and out pop tadpoles. They eat for a few weeks and then the back legs form.
