ANIMALS (VERTEBRATES)

They are acuatic vertebrates that can live in salt water and in fresh waterThey breathe through gillsThey have elongated shape to move through water with less resistance (Hydrodynamic shape)Their body temperature changes with the environment (they are cold blooded animals)

Bony fish (Salmon, trout) Ovíparos

Cartilaginous fish(Shark, rays)Ovovivíparos

Amphibians- They are animals capable of living in terrestrial environments but they need to be near aquatic or humid environments.- Adults breathe through lungs and throgh skin because they are terrestrials. Youngs breathe through gills because they are aquatics- They are cold blooded animalsTwo types:

The frog’s metamorphosis (To change into adults):

Anuros(frogs and toads)

Urodelos(Salamanders)

ReptilesMost of them live on land, but some live in waterThey breathe through lungsThey reproduce by internal fertilization. Female lay eggs from which babies emerge.They are covered with scales.They are cold blooded animals (They have to sunbathe to warm the body)

Turtles

Lizards

Snakes

Crocodiles

BirdsThey have a beakTheir body is covered with feathersThey are hot blooded animals (Their internal body temperature is always the same)They breathe through lungsThey lay eggs (oviparous)

Some of them can fly because: - They have wings - They have hollow and light bones. The lungs go into their bones (air sacs) and help them to breathe while flying. - They have an aerodynamic shape
