1: All amphibians belong to the Vertebrae phylum.
2: Salamanders belong to the order Urodela. They have long bodies and tails with most subspecies having four legs. Both the larvae and the adults are carnivores and live in moist woods, were they tunnel under wood, rocks, and dirt. Some salamanders keep their gills even during adulthood. | Urodela
3: Frogs and toads belong to the order Anura, which is the largest and most common order of amphibians. Frogs live in wet environments while toads are able to live in dry climates such as deserts. Both organisms lack tails as adults. | Anura
4: Cecilians belong to the order Apoda. They are carnivores and eat ants and termites. Caecilians have scales on their outer skin. | Caecilians
5: Ecology | Many species have developed adaptations (such as liberating toxins from skin cells and bright coloring) in order to survive harsh environments. The world population of amphibians is dwindling quickly and scientists do not know why, however. It is believed that acid rain, pollution, habitat loss, and fungal infections are the probable causes.
