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 warmblooded 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
