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.

Invertebrates

Are animals species that do not have a vertebrate

Invertebrates: Echinoderms

Include starfish, sea urchins, and sea cucumbers.

They live in seawater and have external skeletons.

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

Invertebrates: Arthropods

Are the largest and most diverse of all animal group

They have segmented bodies supported by a hard external skeleton

Invertebrates: Sponges

Are the most primitive of animal groups.

They live in water (usually saltwater), are sessile (do not move from place to place).

Vertebrates

Are animals that have a vertebrate

Mammals Fish

Amphibians Reptiles

Birds

Vertebrates: Fish

Breathe through gills, and live in water

Most are cold blooded animals

Lay eggs

Sharks give birth to live young

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.

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.

Vertebrates: Birds

Are warm-blooded animal with feathers and wings

They lay eggs, and most can fly.

Vertebrates: Mammals

Are warm-blooded, and are nourished by their mothers’ milk

Most mammals have body hair.
