Vertebrates

The Animal Kingdom is made up of two groups known as Vertebrates, (animals with backbones) and Invertebrates,

(animals without backbones). The Vertebrate group includes fish, amphibians, reptiles, birds, and mammals.

Fish class• Aquatic animals covered with scales. Fusiform body.• Fins turned into limbs.• Poikilothermic animals, they are cold-blooded

animal.• Respiration by gills.• Swim bladder that allows them to swim between

different waters.• Heart with two cameras.• Sexual reproduction. Oviparous with external

development.

FISH

Class Amphibians• Animals double life, there is the name, in the juvenile stage

live in water, adult metamorphose and earth pass, in wet areas near water.

• Body naked or with very thin skin.• Poikilothermic animals, ie they are cold-blooded animals.• Breathing through gills in the larval stage and lungs and

skin in adulthood.• Heart with three cameras.• Sexual reproduction, internal fertilization, oviparous with

external development. • The first vertebrates to colonize the terrestrial

environment, while still depending on the water.

AMPHIBIANS

Class Reptiles• Terrestrial vertebrates.• Body covered with scales.• Poikilothermic animals, they are cold-blooded

animals.• Breathing lungs.• Four-chambered heart.• Sexual reproduction, internal fertilization,

oviparous with developing eggs showing sheaths that protect and nourish the embryo and shell.

REPTILES

Class Aves• Flying animals.• Body covered with feathers.• Forelimbs modified for flight: wings.• But toothless beak.• Warm-blooded animals, meaning they are warm-

blooded animals.• Breathing lungs.• Four-chambered heart.• Sexual reproduction, internal fertilization, oviparous

with developing eggs showing sheaths that protect and nourish the embryo and shell.

AVES

Class Mammals• Terrestrial animals, aquatic and flying.• Hairy bodies• Presence of the mammary gland which is fed pups ..• Warm-blooded animals, meaning they are warm-blooded

animals.• Breathing lungs.• Four-chambered heart.• Carnivores, herbivores, omnivores.• Sexual reproduction, internal fertilization, almost all viviparous

animal develops the new inside the body, and is powered by a body known as placenta, bear their young and developed
