1 Phylum: Chordata Subphylum: Vertebrata Classes: Chondrichthyes Osteichthyes Amphibia Reptilia Aves Mammalia

2 Phylum: Chordata Characteristics: 1.*Have a dorsal notochord, that becomes the spine. 2.An endoskeleton made of cartilage or bone. 3.Pharyngeal slits or gill pouches during development. 4.A dorsal nerve cord. 5.Post-anal tail Subhylum: Vertebrata Major Characteristic: have a backbone Primitive organism: amphioxus

4 Class: Chondrichtyes *Cartilaginous fish - from, chondro- (cartilage) and ichthyes (fish) -skeleton made of cartilage. -have fins and scales. -breathe with gills. Examples: sharks, skates, and rays.

5 Chondrichtyes Class: Chondrichtyes CHARACTERISTICS: Vertebrates Ectothermic (cold-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of Cartilage Circulatory System – 2 chambered heart Reproduction – External fertilization, many eggs *Dioecious = two distinct genders

6 Heterodontiformes - horn sharks

7 Orectolobiformes - whale sharks Rhincodon typus

8 Orectolobiformes – nurse sharks Ginglymostoma cirratum Ginglymostoma cirratum

9 Lamniformes - mackerel, mako, white sharksMako Great White, Carcharodon carcharias Mako Great White Isurus oxyrinchus

10 Carcharhiniformes - requiem sharks (blacktip) blacktip shark Carcharhinus limbatus Carcharhinus limbatus

11 Carcharhiniformes - requiem sharks (whitetip) Triaenodon obesus

12 Carchariniformes – bull sharks Carcharhinus leucas copyright FLMNH

13 Carchariniformes – tiger sharks Galeocerdo cuvier © George Burgess

14 Carchariniformes – basking sharks Cetorhinus maximus

15 Superorder Squatinomorphi –Squatiniformes-angel sharks bottom-oriented, enlarged pelvic fins, spike-like teeth Atlantic Angel Shark, Squatina dumeril

16 Squaliformes Squaliformes dogfish sharks dogfish sharks Spiny dogfish-Squalus acanthus Adipose spine

17 Pristiophoriformes - saw sharks

18 Myliobatiformes - sting rays eagle & manta rays butterfly rays

19 Rajiformes - skates

20 Skate or Ray...whats the difference? –Skates (order Rajiformes) –pelvic fin divided into two lobes –stocky tail w/o stinging spine –enlarged, thorn-like scales ('bucklers') along the midline of back –males have rows of enlarged scales near the eyes and wingtips –Rays (order Myliobatiformes): – one-lobed pelvic fin –whip-like tail, usually with stinging spine –no bucklers along back or tail

21 Pristiformes - sawfishes

22 Torpediniformes - electric rays

23 Class: Osteichthyes BONY fish - from, osteo- (bone) and ichthyes (fish) -skeleton made of bone. -have fins and scales. -breathe with gills. Examples: bass, tuna, and catfish

24 Class: Osteichthyes bass tuna catfish porcupine fish salmon

25 Osteichthyes Class: Osteichthyes CHARACTERISTICS: Vertebrates Ectothermic (cold-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of BONE Circulatory System – 2 - chambered heart Reproduction – External fertilization, many eggs *Dioecious

26 Class: AMPHIBIA *Amphibians - means double life, part of life spent on water and part on land -smooth, moist skin. -live near water -go through metamorphosis -no claws or scales. Examples: frogs, toads, newts, salamander

27 Class: Amphibia bullfrog Cameroon toad poison dart frog

28 General Amphibians

29 AMPHIBIA Class: AMPHIBIA CHARACTERISTICS: Vertebrates Ectothermic (cold-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of BONE Circulatory System – 3-chambered heart Reproduction – External fertilization, eggs laid in water *Dioecious

30 Class: REPTILIA *Reptiles - body covered w/scales or plates -have lungs/scales & plates/claws -1 st to use the amniotic egg. -also use internal fertilization Examples: turtles, snakes, alligators, lizards

31 Class: Reptilia chameleon lizard Burmese python cobra alligator

32 REPTILIA Class: REPTILIA CHARACTERISTICS: Vertebrates Ectothermic (cold-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of BONE Circulatory System – 3-chambered heart Reproduction – INTERNAL fertilization, AMNIOTIC egg *Dioecious

33 Lizards Komodo Dragon Geckos Frilled Lizard Horned Lizard Chameleon Gila Monster

34 Class: AVES *BIRDS -have wings and feathers. -most fly. Ex: penguin, ostrich, emu -parents incubate eggs. -descended from dinosaurs -lightweight, hollow bones Examples: eagle, owl, cardinal, dove, quail

35 AVES Class: AVES CHARACTERISTICS: Vertebrates ENDOTHERMIC (WARM-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of BONE Circulatory System – 4-chambered heart Reproduction – INTERNAL fertilization, AMNIOTIC egg *Dioecious

36 Class: MAMMALIA *Mammals -have hair & mammary glands. -give birth to live young -have a diaphragm Examples: bats, whale, elephant, deer, horse, human, monkey, rabbits

37 MAMMALIA Class: MAMMALIA CHARACTERISTICS: Vertebrates ENDOTHERMIC (WARM-blooded) BILATERAL symmetry Coelomate Digestive System – COMPLETE Skeletal System – made of BONE Circulatory System – 4-chambered heart Reproduction – INTERNAL fertilization, LIVE YOUNG *Dioecious
