The Animal Kingdom Vertebrates and Invertebrates By Sharon

The Animal Kingdom: Vertebrates and Invertebrates By: Sharon Kallaji and Heather Milewski

All living things can be put into one of five groups called Kingdoms. The five Kingdoms are: Bacteria Protists Fungi Plants Animals

Bacteria Protists • Have no nucleus • Are mostly single celled, but some are simple many celled organisms • Are single celled organisms • Have a nucleus and organelles

Fungi • Are many celled organisms • Do not make their own food • Absorb food from their environment

Plants • Have chlorophyll • Make their own food • Are many celled organisms • Have cell walls

• Are many celled organisms • Do not make their own food • Obtain food by eating

All animals can be classified as belonging to one of two phyla (plural for phylum) based on the characteristic below: Those with OR Backbones Those without Backbones

Animals without Backbones are called Invertebrates.

There are many different types of Invertebrates: • Sponges • Anemones and Jellyfish • Worms • Snails, Clams and Octopuses • Starfish and Urchins • Insects, Spiders, Ticks, Lobsters, Crabs, and Crayfish

Sponges • Are simple animals • Have only two cell layers • Have no Backbone

Anemones and Jellyfish • Have tentacles and stinging cells • All live in water • Feed themselves with their tentacles • Have no Backbone

Worms • Can be flat, round, or segmented • Flatworms have a flat body • Roundworms have a round body • Segmented worms are divided into small sections • Have no Backbone

Snails, Clams and Octopuses • Often have shells • Have a head, foot and well developed organs • Have no Backbone

Starfish and Urchins • Have a spiny body • Are arranged in a circle, like spokes on a wheel • Live on the bottom of the Ocean • Have no Backbone

Insects, Spiders, Lobsters, Crabs and Crayfish • Have a shell like covering called an exoskeleton • Have jointed legs • Have a segmented body • Have no Backbone

Animals with Backbones are called Vertebrates.

There are five classes of Vertebrates: Fish Reptiles Amphibians Birds Mammals

Fish • Most are cold-blooded • Absorb oxygen through gills • Most have scales • Live in water

These are Fish

Fish are vertebrates meaning they have backbones

Reptiles • Are covered with scales • Most live on land • Are cold-blooded • Usually lay egg

These are Reptiles

Reptiles are vertebrates meaning they have backbones

Amphibians • Live in water and on land • Are cold blooded • Have smooth skin that molecules can pass through • Lay their eggs in water

These are Amphibians

Amphibians are vertebrates meaning they have backbones

Birds • Have feathers • Are warm-blooded • Have hollow bones • Lay eggs • Birds have wings, but not all can fly • Have beaks

These are Birds

Birds are vertebrates meaning they have backbones

Mammals • Have hair or fur • Are warm-blooded • Feed milk to their young • Most bear live young

These are Mammals

Mammals are vertebrates meaning they have backbones

Review • Animals without Backbones are called invertebrates: • Animals with backbones are called vertebrates: • Sponges • Fish • Anemones and Jellyfish • Reptiles • Worms • Amphibians • Snails, Clams and Octopuses • Birds • Starfish and Urchins • Mammals • Insects, Spiders, Ticks, Lobsters, Crabs, and Crayfish
