Amphibians are naked while mammals possess hair on skin .
Fur or hair.
As bats are mammals, they have a body covering of fur.
Bilbies have a body covering of fur, as they are mammals (mammals are covered with fur, hair or skin). The fur acts as insulation and helps protect them against extremes of temperature in their environment.
It prevents them getting fleas and other parasites.

Vertebrates are animals that have a backbone, which is composed of individual vertebrae. This group includes mammals, birds, reptiles, amphibians, and fish. The backbone serves as a structural support for the body and also houses and protects the spinal cord.
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 skinAll 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.

There are mammals that are truly ectothermic. However the naked mole-rat does not regulate its body temperature in typical mammalian fashion and unlike other mammals its body temperature tracks ambient temperatures.
This is called internal fertilization. It happens in birds and mammals, whereas amphibians emit eggs and sperm to meet in the outside world.
There are five main classes of vertebrates, which are:Mammals (Mammalia)Birds (Aves)Reptiles (Reptilia)Amphibians (Amphibia)Fish - which in turn are subdivided into Agnatha (jawless fish without scales, e.g. lampreys and hagfish); Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone); and Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
