What are amphibians?

Amphibians are animals that can live in water and on land. They usually have physiological and behavioral characteristics that adapt to alternating water and land environments. Here are some common amphibians:

1. Frogs: Frogs are one of the most common amphibians. They have well-developed hind legs and can jump and swim. Frogs have smooth and moist skin and usually breed in water.

2. Salamanders: Salamanders are a type of amphibian with long tails and short limbs. They usually live near water or in swamps and breathe through lungs or skin.

3. Toads: Toads are very similar to frogs, but they usually crawl instead of jumping. Toads also breed in water and usually feed on insects and other small invertebrates.

4. Clawed toad: Clawed toads are small amphibians that usually live in grass, gardens and forest edges. They mainly feed on insects and are active at night.

5. Snake-necked turtle: Snake-necked turtles are aquatic amphibians with very long heads and necks, which can prey on small fish, insects and other invertebrates in the water.

6. American salamander: American salamanders are large amphibians with large bodies and well-developed muscles. They usually live in freshwater lakes or rivers. The skin of American salamanders is thick and pitted, which can help them retain water and prevent attacks from predators.

In addition, there are some relatively rare amphibians, such as tree toads, tree dragons, tree frogs, etc. In short, amphibians are a group of animals full of vitality, with strong adaptability, diverse species, and rich behavioral characteristics.
