| Animals can be divided into two groups. | VERTEBRATE AND INVERTEBRATE. |
| Vertebrate animals are those animals that have skull and bony or cartilaginous spine. | Invertebrate animals are characterized by not having bony structures. Invertebrate animals represent the majority of animals on planet Earth. |
| Vertebrate animals can be divided into 5 groups: | Birds Amphibians Mammals Reptiles Fishes |
| BIRDS | Birds are vertebrate animals with the body covered with feathers and with the forelimbs transformed into wings. And they reproduce by eggs. |
| AMPHIBIANS | Amphibians were the first vertebrates to adapt to a semi-terrestrial life. Their skin is bare and wet. And their limbs are muscular legs, which allow them to swim or jump. |
| MAMMALS | They are terrestrial and aquatic animals, some are capable of flying. Their bodies are covered with hair. They breathe through lungs. |
| RESPTILES | Most reptiles are adapted for terrestrial life.. Tneir body is covered in scales. And their limbs are shaped like legs, which are usually very short. Some do not. |
| FISHES | Fish are aquatic, gill-breathing vertebrate animals. They are covered in scales and have fins, which allow them to be in continuous movement in the water. Their body ends in a stronger fin that forms the tail. |
| Invertebate animals also can be divided into 5 groups: | Mollusks Echinoderms Arthropods Worms Poppies and Jellyfish |
| MOLLUSKS | Mollusks lack a vertebral column and an internal articulated skeleton. They have soft bodies and some have shells. |
| ECHINODERMS | Echinoderms are marine and have radial symmetry. |
| ARTHROPODS | Their bodies are articulated in pieces that move. |
| WORMS | Worms are invertebrate animals with a soft and elongated body. They live in moist soils or in water. |
| COELENTRATES | Coelenterates lack an external skeleton, except for Stone Corals. Their respiration is cutaneous, they have radial symmetry, and also have stinging cells. |
