ANIMALS WITH BACKBONES

BackboneIs an animal's spine.It also means determination and strength.

Five main classes of animals with backbones1.Mammals2.Birds3.Fishes4.Reptiles5.Amphibians

Characteristics of mammals A flexible neck with seven cervical vertebrae

Mammals also show enhanced neocortex development

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 mammalsThey have sweat glands

A single jaw bone

Diaphragm

Three bones for a middle ear

Give birth to young alive

Feeds milk to its young

Has hair on its body

HabitatsOn and under the landIn waterIn the air

Examples of mammals:

Gorilla Cat

Dog

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

Habitats On the air

On the land

Spur-winged Plover Nene Goose

Griffin Vulture

Characteristics of fishFish are vertebrates (animals with a

backbone)have gills, scales and fins on their body

In water

Habitat

Examples of fish Maui Ocean Center

Swordtails Velvet swordtails

Characteristics of reptilesReptiles are a class of animal with scaly skin. They are cold blooded and are born on landEctodermicLateral lineTwo chambered heartGills used for respirationNo external earsNo eye lids

Habitats

They live in hot deserts, swamps, tropic jungles, dark caves and even in the ocean there is many places where they can live you see.

Examples of reptiles

Anole Turtle

Chameleon

Examples of reptiles

American Alligator

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.
