What are 10 characteristics of amphibians?

Below are some of the characteristics shared by the amphibians.

1. Time Spent In Water and On Land.
2. Carnivores.
3. Breathe Through Skin.
4. Cold-Blooded.
5. Egg Are Fertilized Outside of the Body. Most amphibians reproduce in fresh water while a few lay their eggs on land and have developed mechanisms to keep the eggs moist.

How do you identify an amphibian?

An amphibian is a cold-blooded vertebrate animal that includes frogs, toads, newts and salamanders. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.

What makes frogs unique?

What are the special features of an amphibian?

The characteristics of the organisms present in class amphibia are as follows: These can live both on land and in water. They are ectothermic animals, found in a warm environment. Their body is divided into head and trunk. The skin is smooth and rough without any scales, but with glands that make it moist. They have no paired fins. They have two pairs of limbs for locomotion. They respire through the lungs and skin.

What is unique about amphibians?
