Three orders of amphibians

Order Caudata (salamanders, 400 species)

Habitat: terrestrial or aquatic
* Carnivorous during the larval and adult stages
*Walk with a side to side bending of the body
*Most salamanders have limbs of equal size set at right angles to the body
*Some salamanders with an aquatic larval stage hatch with gills which they lose later on during metamorphosis
*Others do not undergo metamorphosis but retain the larval features example, mud puppies

Order Anura (frogs and toads, 3500 species)

*Enlarged hindlegs provide better movement (hopping) than in Caudata
*Capture prey by flicking stick tongue
* Predator avoidance aided by camouflage
* Bright coloration in poison species


Order Apoda (caecilians, 150 species)
* Legless and almost blind, Most are found in moist tropical soils, a few are found in freshwater ponds and streams
