Animals with backbones are called vertebrates.Vertebrates include many different kinds of animals. They can be found just about everywhere – in oceans, rivers, forests, mountains, and deserts.Animals with backbones can be broken up into smaller groups by characteristics.They are:

Animals With BackbonesSlide4

FishSlide5

Fish CharacteristicsThey are the largest group of vertebrates.They can be further categorized

Agnatha

-Jawless fish

Chondrichthyes

-sharks and raysSkeletons of cartilage Osteichthyes-bony fishSkeletons of boneTheir

body temperatures vary in the water.exothermicThey breathe through gills.Slide6

AmphibiansSlide7

Amphibian CharacteristicsTheir body temperature varies with their surroundings.exothermic

Amphibians hatch from

eggs in the water

and they can live on land as an adult.

Young amphibians breathe through gills like fish.Adult amphibians breathe air from lungs.Example: frogsSlide8

ReptilesSlide9

Reptile CharacteristicsThey lay their eggs on land.They have dry scaly skin.They can include animals as large as a crocodile.

Their body temperature varies with their environment

.

exothermic

They live in hot, dry deserts and in warm, wet tropical rain forests.Examples: snakes and lizardsSlide10

BirdsSlide11

Bird CharacteristicsBirds lay hard shelled eggs that hatch in their nest.Birds are vertebrates that have wings and they are covered with feathers.

The

bird’s skeleton is very light in weight.

Their bones are hollow

This helps them to fly.Are thought to have evolved directly from dinosaurs.

Regulate their own body temperature through metabolismendothermicSlide12

MammalsSlide13

Mammal CharacteristicsTheir young grows inside the mother.Placental birth

Have hair

Warmth and protection.

They feed milk to their young

.Regulate body temperature through metabolismendothermsSlide14

InvertebratesSlide15

Invertebrate ClassificationWhat is an Invertebrate?Invertebrates are animals that do not have backbones.

97 % of the animal kingdom is made up of invertebrates.

Insects

and some other invertebrates have exoskeletons.Slide16

An Exoskeleton is a hard outer covering that protects an animal’s body and gives it support.

There

are six groups of invertebrates. They are:Slide17

Porifera-SpongesSlide18

Sponges CharacteristicsThey look like plants but they are animals.Sponges stay fixed in one place-sessile.Their bodies are full of holes and their skeleton is made of spiky fibers.

Water flows through the holes of their body which enables them to catch food.Slide19

Cnidaria: Corals, Hydras, and JellyfishSlide20

CharacteristicsCorals look like plants but they belong to the animal kingdom.They have soft tubelike

bodies with a single opening surrounded by

armlike

parts called tentacles.

They feed by catching tiny animals in their tentacles.Hydras have tentacles that catch their food.They move from place to place-mobile.Slide21

Worms: Flatworms, Roundworms, and Segmented wormsSlide22

Worm CharacteristicsWorms are tube-shaped invertebrates which allows them to be put into groups.They can be found in both land and water environments.Slide23

Platyhelminthes-FlatwormsThey have a head and a tail, and flattened bodies.A tapeworm is a flatworm that can live inside the body of animals and humans. parasiteSlide24

Nematoda-RoundwormThey have rounded bodies.Includes Ascaris, hookworms,

Trichinella

, & pinwormsSlide25

Annelids-Segmented wormsThe earthworm belongs to this group of worms.Body divided by grooves into septa

Evolved from roundworms.

Have a real circulatory system.

Rudimentary nervous system.

Hermaphrodites Slide26

Starfish and Sea UrchinsSlide27

Echinodermata-Characteristicshave tiny tube feet and body parts arranged around a central area.

No head

Rudimentary nervous and circulatory system

The

hard, spiny covering of the starfish gives the animal protection.Can regenerate lost or injured parts.Slide28

MollusksSlide29

Mollusk CharacteristicsA soft bodyMost have internal or external shell

Muscular foot and/or tentacles

Distinguishable head and foot region

Have a heart, blood vessels, digestive system and nervous system

Radula: a series of teeth on cartilage base for feedinginclude snails, sea slugs, octopuses, squid, and bivalves such as clams, mussels and oysters.Slide30

ArthropodsSlide31

Arthropod CharacteristicsArthropods are a group of invertebrates with jointed legs and hard exoskeleton that protect the arthropod.As it grows, it molts, or sheds its old exoskeleton.

Then it grows a new exoskeleton that allows its body to continue to grow.

The

largest group of arthropods are insects.Slide32

Arthropods: Insects, Spiders, and Centipedes/MillipedesChitinous exoskeleton-must be shed during growthPaired appendages are jointed

Segmented bodies arranged into regions

Head, thorax, abdomen

Bilateral symmetrySlide33
Taxonomy

Subphylum Chelicerata Class Merostomata - horseshoe crabs, Class Arachnida - spiders, scorpions, ticks, mites Subphylum

Crustacea

- crustaceans

Subphylum Uniramia

Class Chilopoda - centipedes Class Diplopoda - millipedes

Class Insecta - insects Order Hymenoptera - ants, bees, wasps Order Coleoptera - beetles Order Lepidoptera - butterflies, moths Order Diptera

- flies, mosquitoes Order Orthoptera - grasshoppers, crickets, roaches Order Odonata - dragonflies Order Isoptera - termites Slide34
