| True or False? Amphibians lack scales, feathers, and hair. | TRUE |
| Most amphibians are oviparous. Do they lay eggs or give live birth? | They lay eggs. |

| These organs located in an amphibians skin produce toxins to prevent infection and make them distasteful to predators. | granular glands |
| Frog or Toad? Closely tied to the water, generally smooth appearance. | frog |
| Frog or Toad? Not closely tied to water, generally bumpy or warty appearance. | toad |
| Larval stages of an amphibian. | tadpoles |
| Tadpole or adult amphibian? Aquatic, breathes with gills, legless, caudal fin for movement, and herbivorous. | tadpole |

| Two main characteristics of juvenile salamanders and newts. | external gills and caudal fin |
| Type of amphibian with costal grooves to help distribute water across its body. | salamander |
| Type of amphibian metamorphosis in which the aquatic juvenile morphs into terrestrial adults. | complete metamorphosis |
| Type of amphibian metamorphosis in which the aquatic juvenile must stay in the water, even as an adult. | obligate paedomorphosis |
| Type of amphibian metamorphosis in which the aquatic juvenile stays in the water unless it dries up, then it morphs into the adult form and move on land. | facultative paedomorphosis |
| How are caecilians easily distinguished from snakes? | snakes have scales and caecilians do not. |
