What makes amphibians different from other animals?
Almost all amphibians have thin, moist skin that helps them breathe. No other group of animals has this special skin. Most amphibians undergo a unique change from larvae to adults, called metamorphosis.
How are amphibians different from other terrestrial animals?
Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land. Unlike fish, they can breathe atmospheric oxygen through lungs, and they differ from reptiles in that they have soft, moist, usually scale-less skin, and have to breed in water.
What makes an amphibian unique?
Modern amphibians are united by several unique traits. They typically have a moist skin and rely heavily on cutaneous (skin-surface) respiration. They possess a double-channeled hearing system, green rods in their retinas to discriminate hues, and pedicellate (two-part) teeth.
What do amphibians have that other animals don t?
The species in this group include frogs, toads, salamanders, and newts. All can breathe and absorb water through their very thin skin. Amphibians also have special skin glands that produce useful proteins. Some transport water, oxygen, and carbon dioxide either into or out of the animal.
What are 3 differences between amphibians and reptiles?
Reptiles are born with lungs, while amphibians are born with gills for breathing under water—where they hatch and spend their early development (growing lungs and legs later). Reptiles have scales, while amphibians have thin, smooth skin. Snakes, turtles, and lizards are reptiles.

What are animals that are amphibians?
Amphibians are a class of cold-blooded vertebrates made up of frogs, toads, salamanders, newts, and caecilians (wormlike animals with poorly developed eyes).

What is the difference between a mammal and an amphibian?
Mammals exhibit internal fertilization while amphibians exhibit external fertilization. Mammals have mammary glands for the production of milk to feed their babies. But, amphibians do no exhibit such parental care. This is the main difference between mammals and amphibians.
What is a key morphological difference between fish and amphibians?
Difference Between Fish and Amphibians
| Fish | Amphibians |
|---|---|
| Scale covered skin | No scales, but moist skin |
| Respiration mainly through gills, except lungfishes | Respiration takes place through lungs mainly. However, skin, oral cavity, and gills are also functional in any combination of those according to the environment they live |
