• Armadillos are mammals (they have hair, give live birth - except for monotremes which are an exception but armadillos are not monotremes - and nurse young with milk).
• Birds are in their own class Aves (they have feathers, beaks, and are endothermic).
• Caecilians are amphibians (they have moist skin, many go through metamorphosis, and are often associated with moist environments).
• Salamanders are amphibians (they have moist skin, many have an aquatic larval stage, and are ectothermic).
