Amphibians are a class of vertebrates that includes frogs, toads, salamanders, and newts. They are characterized by their ability to live both on land and in water, as well as their unique life cycle that involves metamorphosis from a larval stage to an adult stage.
Classification of Class Amphibia:
Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Characteristics of Class Amphibia:
1. Skin: Amphibians have moist, permeable skin that allows them to absorb oxygen and water directly from their environment. This makes them highly sensitive to changes in their habitat, such as pollution or temperature fluctuations.
2. Life Cycle: Most amphibians undergo metamorphosis, starting as aquatic larvae with gills and eventually developing into adults with lungs and limbs. This process allows them to adapt to different environments throughout their life cycle.
3. Limbs: Amphibians typically have four limbs, although some species have reduced or even lost their limbs through evolution. Their limbs are adapted for both swimming and walking on land.
4. Reproduction: Amphibians reproduce through external fertilization, with males releasing sperm and females releasing eggs into the water. Some species also exhibit parental care, with adults guarding and caring for their eggs and young.
5. Habitat: Amphibians are found in a wide range of habitats, including freshwater ponds, streams, forests, and even deserts. They are particularly sensitive to changes in their environment, making them important indicators of ecosystem health.
6. Diet: Most amphibians are carnivorous, feeding on insects, small invertebrates, and sometimes even other amphibians. Some species are also known to be opportunistic feeders, consuming a variety of plant and animal matter.
7. Sensory Organs: Amphibians have well-developed sensory organs, including eyes, ears, and a specialized organ called the lateral line system that detects vibrations in the water. These adaptations help them navigate their environment and locate prey.
Overall, amphibians are a diverse and fascinating group of animals with unique adaptations that allow them to thrive in a variety of habitats. However, many amphibian species are currently facing threats such as habitat loss, pollution, and climate change, making conservation efforts crucial to their survival.

Classification of Class Amphibia
Amphibia is a class within the phylum Chordata and belongs to the subphylum Vertebrata. Amphibians are further divided into three orders:
- Order Anura: Frogs and toads (lack a tail in adulthood)
- Order Caudata: Salamanders and newts (possess a tail in adulthood)
- Order Gymnophiona: Caecilians (legless and highly adapted for burrowing)
Characteristics of Class Amphibia
1. Metamorphosis:
- Most amphibians undergo metamorphosis from an aquatic larval stage (tadpoles) to a terrestrial adult stage.
- Metamorphosis involves changes in body form, diet, and respiratory system.
2. Permeable Skin:
- Amphibians have highly permeable skin that enables them to absorb oxygen and water.
- Their skin is also glandular, secreting substances that can aid in defense or attract mates.
3. Amphibious Lifestyle:
- "Amphibia" means "double life." Amphibians typically have an aquatic larval stage and a terrestrial adult stage.
- They inhabit both aquatic and terrestrial environments.
4. Three-Chambered Heart:
- Amphibians have a three-chambered heart (two atria, one ventricle).
- This heart design is intermediate between fish (two chambers) and reptiles (four chambers).
5. Lay Aquatic Eggs:
- Amphibians typically lay their eggs in water.
- The eggs are gelatinous and fertilized externally.
6. Ectothermic ("Cold-Blooded"):
- Amphibians cannot generate their own body heat and rely on external sources for body temperature regulation.
7. Smooth Muscles:
- Amphibians have smooth muscles in their skin, digestive tract, and other organs.
8. Relatively Small Size:
- Amphibians are generally small animals, ranging in size from tiny caecilians to large bullfrogs.
9. Parental Care:
- Some amphibian species exhibit parental care, such as guarding eggs or carrying tadpoles on their backs.
10. Role in Ecosystems:
- Amphibians play important roles in aquatic and terrestrial food webs as both predators and prey.
- They serve as indicators of environmental health due to their sensitivity to habitat disturbances.
