Key Concepts Covered in Section 30 3: The Amphibians

1. Characteristics of Amphibians

Amphibians are a unique class of cold-blooded vertebrates known for their dual life stages—aquatic and terrestrial. Understanding their characteristics is crucial for grasping their biological significance.

• Skin: Moist, smooth, and glandular, often involved in respiration.
• Larval Stage: Typically begins with a gill-breathing larva (tadpole).
• Respiration: Via skin, lungs, and gills during different life stages.
• Circulatory System: Double circulatory system with a three-chambered heart.
• Reproduction: Usually involves external fertilization.

2. Classification and Examples of Amphibians

Amphibians are classified into three main orders:

1. Order Anura: Frogs and toads
2. Order Caudata (Urodela): Salamanders and newts
3. Order Gymnophiona (Apoda): Caecilians

Each order exhibits distinct features but shares common amphibian traits.

3. Life Cycle of Amphibians

The amphibian life cycle is a classic example of metamorphosis, transitioning from aquatic larvae to terrestrial adults.

1. Egg Stage: Laid in water, fertilized externally.
2. Tadpole Stage: Develop gills, tail, and a mouth; herbivorous and aquatic.
3. Metamorphosis: Gills replaced by lungs; limbs develop; tail reabsorbed.
4. Adult Stage: Terrestrial or semi-aquatic, capable of reproduction.
