Characteristics of a Reptile

They are ecothermic lime fish ( their temperatures adapts to the temperature of the invoroment ) they breath through their lungs . They are carnivore ( they eat animal ) . They are oviparous animals ( they lay eggs )

Amniotic eggs

This means the zygote is inside the egg but it has a menbranes that is named amniot .

Characteristics of Mammals

They are endothermic ( they mantain their own heat) they breath throught their lungs . They can be carnivores ( they eat animals , herbivores ( they eat plants ) or they can be omnivores ( they eat both ) and they are viviparous ( they give birth ) .

Marsupials

They are vivparous but they don't have a proper placenta . They complete birth in mother pouch .

Monotremes

They are the only mammals that they are oviparous they have fur feed their young with milk j

Amphibians characteristics

They are cold blodded animals wich means they don't releise there own heat they need to absorb it from the sun .

They breath mainly through the skin , but they can akso can breath through their lungs . They are oviarous (they lay eggs )

The metamorphosis

1. The eggs hatch

2. The egg slowly become and turns into a tadpole ( like a fish with leggs)

3. Then it developes and turns into an adult

4. After that the male and female leaves the speem and egg around and the egg is formed again

Birds Characteristics

They are endothermic wich means they are able to mantain their own heat ( releaise their own heat ). They breath through the lungs , they are oviparous ( they lay eggs ) they are omnivores( they eat animal such as plants)

Amnitotic eggs

This means the zygote is inside the egg but it has a menbranes that is named amniot .

Characteristics of fish
They are mostly carnivores ( eat animals ) some are hervivores( they eat plants ). They lay eggs wich means they are oviparous .
They are ecothermic wich means their body temperature  changes acording to the temperature of the enviroment

Breathing of fish

Water come through the operclum passa through the gill and goes out again when the operclum opens .

Types of fish

We have two types of fish :

Cartilaginous fish

This means that instead of bones they have cartilage and the gills are directly in contact in the water

Bony fish

This type of fish have the skeleton made of bone an their gills are covered with a cover ( operclum )
