Anura - Frogs and toads are amphibians of the order Anura. There are nearly 5,000 recognized species of frog in the world, with more frequently discovered or defined. In fact, anuran taxa are moved around quite often, and changes at the family level are not uncommon.  Anurans are highly diverse, and have the widest distribution of the amphibian orders, which includes nearly every continent. For more information abut anurans, see the Anura Info & Database section.
	Caudata - Salamanders, newts, sirens, amphiuma, waterdogs, and mudpuppies are amphibians of the order Caudata, or Urodela. There are more than 500 recognized caudates in the world, with the highest concentration in the Americas. Major discoveries in the caudate order are less frequent than in the anuran order, but new genetic information often results in the reevaluation of existing classifications, and occasionally modifications at a higher level than species. Caudates are found mostly in temperate zones of the Northern Hemisphere, with a few genera found in Central and South America, the tip of Africa, and extreme northern India. For more information abut anurans, see the Caudata Info & Database section.
	Gymnophiona - Caecilians are amphibians of the order Gymnophiona, or Apoda. Caecilians are long, segmented amphibians that may superficially resemble giant earthworms. The physical appearance of caecilians makes them undoubtedly distinguishable from any other amphibian order. Some species are aquatic, while others are terrestrial, or more accurately, fossorial. Caecilians are found in South America, Africa, and Asia. For more information abut anurans, see the Gymnophiona Info & Database section.
	Embryonic, Larval, and Young Amphibians - The typical life cycle of an amphibian begins with a gelatinous egg that hatches into an aquatic larvae, followed by metamorphosis into a terrestrial or aquatic amphibian. However, amphibians have evolved a few different methods of development. In fact, there are ovoviviparous, and viviparous amphibians, in addition to the common oviparous type. The photos in this section are arranged in a way that attempts to give a brief view of the lifecycle from egg, larvae, or metamorph, to adult. This section contains dozens of thumbnails, and may take a several minutes to load completely.
	Habitats - Amphibians are found in nearly every niche of the world, from the tropics to the snow, and everything in between. This section contains dozens of photos of wild and captive habitats, and may take several moments to load completely.
