Can live on land and water. Exothermic (cold-blooded). Have smooth, moist skin. Have a backbone. Have 4 limbs – distinct front and back legs. Scientist classify organisms based on many factors. Let’s learn!. Organisms can be grouped, or . classified. , according to similarities and differences in their physical characteristics. .. Classifying Animals. Adaptations to Meet Challenges of Life on Land. Challenges of Life on Land vs. Water. Adaptation to Meet Challenge . Air much less buoyant than water so must move against gravity. Limbs develop;. skeletal and muscle systems become stronger. Test 2: Amphibians and Reptiles:. Objective 1: Describe the characteristics of Modern Amphibians. 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..
