1. Vertebrate and Invertebrates 4.L.1.2. Students are able to differentiate between vertebrates and invertebrates, and classify the five groups of vertebrates (mammal, reptile, amphibian, bird, and fish) based on characteristics.

2. Invertebrates  Are animals species that do not have a vertebrate

3. Invertebrates: Echinoderms  Include starfish, sea urchins, and sea cucumbers.  They live in seawater and have external skeletons.

4. Invertebrates: Mollusks  Soft bodied animals, which often live in hard shells  Include snails, slugs, octopus, squid, mussels, oysters, clams, scallops, cuttlefish  50,000 livening species

5. Invertebrates: Arthropods  Are the largest and most diverse of all animal group  They have segmented bodies supported by a hard external skeleton

6. Invertebrates: Sponges  Are the most primitive of animal groups.  They live in water (usually saltwater), are sessile (do not move from place to place).

7. Vertebrates  Are animals that have a vertebrate

8. Vertebrates: Fish  Breathe through gills, and live in water  Most are cold blooded animals  Lay eggs  Sharks give birth to live young

9. Vertebrates: Reptiles  Reptiles: Are cold blooded and breathe with lungs. They have scales and most lay eggs.  Reptiles are snakes, turtles and tortoises, crocodiles and alligators, and lizards.

10. Vertebrates: Amphibians  Are cold blooded  Live both on land and water (BREATH WITH LUNGS)  In water (BREATH THROUGH GILLS)  Three types are frogs, toads, salamander and caecilians.

11. Vertebrates: Birds  Are warm-blooded animal with feathers and wings  They lay eggs, and most can fly.

12. Vertebrates: Mammals  Are warm-blooded, and are nourished by their mothers’ milk  Most mammals have body hair.
