1 Kingdom Animalia Phylum Chordata Most are classified as VERTEBRATES – organisms with a backbone

2 Supraclass Pisces Fish Ectothermic - cold- blooded Gills for gas exchange Water habitat Scavengers, carnivores, predators, parasites Swim with fins External fertilization (bony fish) Separate sexes Bilateral symmetry

3 Class Agnatha Jawless Fish – lampreys & hagfish Lampreys: live in salt and freshwater Parasitic- round mouth lined with teeth Parasitic- round mouth lined with teeth Slimy skin, no scales Slimy skin, no scales

4 Hagfish: scavengers Use 6 short tentacles surrounding the mouth to find its food Use 6 short tentacles surrounding the mouth to find its food Blind Blind

5 Class Chondrichthyes Cartilaginous Fish – shark, ray, & skates Sharks paired fins streamlined bodies predators - rely on sense of smell and movement Rays and Skates flat, wide bodies with long thin tails for life on ocean bottom large pectoral fins (look like wings)

6

7 Class Osteichthyes Bony Fish – ex. Perch, trout, bass scales covering the body skeleton made of bone swim with the aid of fins have swim bladder that works like a balloon

8

9 Class Amphibia – frogs, toads, salamanders, & newts Characteristics “Double Life” -lives part of its life in water and part on land ectothermic no scales or claws Have thin, moist skin

10 larvae are herbivores, adults carnivores larva have tails to move in water external fertilization with no parental care lay eggs without shells in water

11 Body Plan Bilateral symmetry Bilateral symmetry 3 chambered heart 3 chambered heart Larvae breathe through gills; adults breathe through lungs Larvae breathe through gills; adults breathe through lungs Breathe through thin, moist skin (produces mucus) Breathe through thin, moist skin (produces mucus) Changes from larva to adult through Changes from larva to adult through the process of metamorphosis

12 Class Reptilia – snakes, lizards, turtles, alligators Characteristics First vertebrate to live and reproduce entirely on land Ectothermic Carnivores or omnivores Have scales and claws Internal fertilization with no parental care Lay amniotic eggs with leathery shells

13 Body Plan Bilateral symmetry Bilateral symmetry 3 chambered heart 3 chambered heart Breathe through lungs Breathe through lungs Dry, scaly skin prevents water loss Dry, scaly skin prevents water loss

15 Class Aves Birds CharacteristicsEndothermic Has feathers and two legs covered with scales Front limbs are wings Beaks, claws and good vision help birds get food Carnivores, herbivores, insectivores Internal fertilization Amniotic eggs with hard outer shell

16 Body Plan Wings Wings 4-chambered heart 4-chambered heart Lungs Lungs Hollow bones Hollow bones Strong breast muscles Strong breast muscles

20 Class Mammalia Characteristics Hair or fur at some stage of development Give birth to live young (except Monotremes) Endotherms Herbivores, carnivores and omnivores Walk, swim, or fly Sexual (egg and sperm) with separate sexes Internal fertilization

21 Body Plan Internal skeleton Internal skeleton Complex organ systems Complex organ systems Mammary glands (for milk) Mammary glands (for milk) Four-chambered heart Four-chambered heart Lungs Lungs

22 Monotremes (lay eggs) Duckbill platypus Duckbill platypus Marsupials (live young develop in a pouch) Kangaroos, koalas Kangaroos, koalas Placental (young develops internally) 12 Orders with examples such as Primates Primates Bats Bats Whales & dolphins Whales & dolphins Walrus & seals Walrus & seals Hoofed livestock Hoofed livestock Rodents Rodents Bears Bears Elephants Elephants
