Which of the following characteristics is not found in the amphibians?

• A. Thin moist skin
• B. Internal fertilization
• C. Aquatic larvae
• D. Egg with gelatinous covering

Answer 1

The correct option is B Internal fertilization

Amphibians are cold-blooded animals, meaning they do not have a constant body temperature but instead take on the temperature of their environment. They have moist, scaleless skin that absorbs water and oxygen. They fertilize their eggs outside of the female's body where the male and female release their gametes. Most amphibians lay their eggs, protected only by jelly, in the water. The young go through a larval stage, breathing through gills and swimming with fins, before transforming into adults.

So the correct answer is "internal fertilization".
