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

Options

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

Explanation

To determine which characteristic is not found in amphibians, we can follow these steps:

### Step 1: Understand the Characteristics of Amphibians
Amphibians are a class of animals that typically live both in water and on land. Common examples include frogs, toads, and salamanders. They have specific characteristics that define them.

### Step 2: Identify Common Characteristics of Amphibians
1. **Moist Skin**: Amphibians have moist skin that allows for gas exchange.
2. **External Fertilization**: Most amphibians reproduce through external fertilization, where eggs and sperm are released into the water.
3. **Aquatic Larval Stage**: Amphibians usually have a larval stage that is aquatic, such as tadpoles in frogs.
4. **Cold-Blooded**: Amphibians are ectothermic (cold-blooded) animals, meaning their body temperature is regulated by the environment.

### Step 3: Analyze the Options
Now, we need to analyze the options provided in the question. Since the specific options are not listed, we will focus on the characteristic that is generally not found in amphibians:
- **Internal Fertilization**: While some amphibians may exhibit internal fertilization, it is not the norm for the majority of amphibians.

### Step 4: Conclusion
Based on the analysis, the characteristic that is not typically found in amphibians is **internal fertilization**. Most amphibians reproduce through external fertilization.

### Final Answer
The characteristic that is not found in amphibians is **internal fertilization**.
