Objective 2: Describe characteristics of the following orders: (. Apoda. , . Urodela. , . Anura. ). Give examples of each.. Amphibians are eukaryotic, heterotrophic vertebrates. They have thin, smooth, moist skin. Some of them have fish-like scales and none of them have claws.. They are ectothermic (coldblooded).. They have external gills and lungs..

Humans have been utilizing the land since the beginning of time, building settlements where there was access to water and fertile soils. Over time developments have been made in order to properly manage land use. Agriculture has been the driving force behind land use, but today there are more needs than just agriculture. Needs such as municipal, transportation, energy, recreation, and waste management. . Spitzen-van der Sluijs A, Martel A, Asselberghs J, Bales EK, Beukema W, Bletz MC, et al.
