Fishes are ectothermic or cold blooded. That means that their body temperature changes to the temperature of the enviroment.
The majority of then are carnivores, that means that they eat other animals. They reproduce by laying eggs, so they are oviparous. They don't have lungs so they breath through gills.
There are 2 main types of fish:
The Cartilaginous fish , that have the skeleton made up of cartilage , and the Bony fish that have the skeleton made up of bones.

Birds are endothermic , which  means  that they're able to produce and maintain their own heat to have a constant body temperature. Regardless to the temperature on the environment.
They lay eggs , so  they're oviparous.  They're  Omnivores because they eat other animals and plants.  Birds are bipeds that means that when they're not flying they walk with 2 legs.

Amphibians are oviparous, they lay eggs on the water. " Baby " Amphibians  are called Tadpoles. Tadpoles are hervibores, however , when they get bigger ,adults , they  are carnivores, that means that eat other animals. Amphibians are cold blooded , that means that their body temperature will change to the temperature of the enviroment. They're tetrapods = 4 feets.They breathe through their skin. All Amphibians do a process  for growing called Metamorphosis .

Mammals are viviparous, that means that they give birth to young already developed inside the mother.  They're endothermic. That means that  they are able to keep a constant body temperature,regardless of the temperature of the environment. Mammals are tetrapods that means that they have 4 feets. Mammals have their body covered up of hair or fur.  Another characteristic  about mammals is that  "moms" have  mammary glands that produce milk to feed their young. Mammals can be  carnivore ( eat other animals), herbivores(eat plants)  or omnivores ( eat other animals and plants).

Most reptiles are terrestrial but some of then are marine, like turtles and cocodriles. Reptiles are oviparous, that means that they lay eggs. Also they are cold blooded, that means that their body temperature changes to the temperature of the enviroment.  They're Carnivores , eat other animals. Have 4 feets, that means that they are tetrapods.  Reptiles have scales made up of keratin which protect then from injury.

Marsupials:
These animals are still viviparous, but they don't have a developed planceta. So their young at birth they complete their development in the mothers pouch. One example : Kangaroo.

Monotremes:
This are the only mammals that are oviparous, that means that they lay eggs. Examples : Echidna, Platypus.
