Sound is produced by the larynx (a modified region of the trachea) limbs are oriented vertically
The mammalian heart has 4 chambers
Internal temperature is generally high
Egg development occurs in the uterus (excluding monotremata)

Characteristics of birdswarm blooded (endothermic) vertebrates (they have a backbone and an
internal skeleton) breathe using lungs (not gills)an outer covering of feathers - this feature is
not shared with any other vertebrate group reproduce by laying eggs

Amphibians characteristicsAmphibians are cold-blooded animals, meaning they
do not have a constant body temperature but instead take on the temperature of their environment.
They have moist, scale less skin that absorbs water and oxygen
The thin skin of amphibians contains many glands, among them poison glands that protect certain species against predators.
Some amphibians protect themselves from enemies by changing color to blend in with their surroundings.

HabitatsAmphibians start their life cycle
underwater and move to land on the onset of their adulthood. They can adapt to a wide range of habitats, even man-made ones.
The preferable habitats of amphibians are wet and damp areas such as wetlands, shallow ponds and marsh pools.
