How are amphibians different from other vertebrates?

Answer 1

The main differences are:

1. Mammals are warm-blooded; amphibians are cold-blooded.

2. Amphibians lay eggs; mammals (except for the monotremes) give live birth.

3. Amphibians are born with gills; mammals have only lungs for their entire lives.

4. Mammals feed their young with milk; amphibians do not.

5. Mammals have fur and (comparatively) dry skin; amphibians have slimy skin and no fur.

6. Amphibians have external reproduction and leave the young; mammals have internal reproduction, and one or both parents take care of the young until they grow old enough to live independently.
There are huge differences between mammals and amphibians in many ways based on their characteristics.

Firstly, they differ from each other based on their body skin. Mammals have a layer of skin (thickness of the fat for each species differs based on the climate and weather) which is coated by fur or hair, whereas amphibians have bare and moist skin.

Mammals' major habitat is land, although some groups of mammals live in the water, for instance whale ps, Dolphins, Narwhals and and manatees. Amphibians have some special characteristics which allow them to stay both in land and in water. Most amphibians will lay eggs in water and young will live in water for some time before they come up to land.

All mammals are warm-blooded, while all amphibians are cold-blooded.

Moreover, the most important characteristics of a mammal is giving birth to the young, with the exception of the platypus and echidna. Most - though not all - species of amphibians lay eggs.
the diference is that mammals have hairy or fury skin when amphibians have smooth skin

All mammals are warm blooded. Most young are born alive.They have hair or fur on their bodies.Mammals feed milk to their babies.

All the amphibians are cold blooded.The does not live birth bit give the eggs which are jelly like.No hairs but skin is moist and rough with several glands.

mammals body temperature stays the same most of the time unless you are sick. amphibians temperature differs depending on the temperature outside.

Answer 2

Amphibians are different from other vertebrates because they begin life in the water but when they grow they live on land but near water. Amphibians normally return to the water where they were born to lay their eggs. Amphibians are basically at home in land or water and have to be constantly hydrated because if there skin dries out they will die.

Answer 3

amphibians are different because they require both land and marine environments in which to live. they have evolved mechanisms for breathing both out of and inside water, and require a marine environment for reproduction.

Answer 4

Amphibians differ form mammals greatly;

Things mammals have but not amphibians:

- Have hair (hair can be specialised e.g. hedgehog/porcupine spines)

- Give birth to live young (with two exceptions, the platypus and equidna)

- Feed their offspring on milk produced by the mother

- Are warm blooded

Hope this helps!

Answer 5

Mammals have a skin that conserves water and do not need to stay moist, but amphibians must stay wet because they do part of their breathing via the skin, and they cannot effectively hold water within their body. Mammals are warm blooded with four chambered hearts, but amphibians are cold blooded and have three chambered hearts. Amphibians lay eggs in water, but most mammals give birth to live young (except a few that lay eggs on land). Amphibians go through metamorphosis, mammals do not. Mammals also have hair and produce milk for their young.

Answer 6

an amphibian breathes underwater with gills
