  3. Announcements….TURN IT IN! Diagram on pg. 766 • Turn in StarFish Dissection Lab Sheets • Absent Friday? GO ONLINE to review the starfish dissection PowerPoint and answer lab questions • Pre-Lab worksheets (50pts) • Actual Dissection + Lab Questions (50pts) • 100 points total! • DUE TODAY! • 15 minutes

  4. Begin taking notes!!! Vertebrates Most vertebrates belong to the phylum Chordata. Members of this phylum are called CHORDATES. These animals have a stiff but flexible rod called a notochord that gives their body support. Vertebrate differ from other chordates because they have a BACKBONEand a skull made of BONE or cartilage.

  5. Vertebrates continued • Vertebrates may be ectotherms or endotherms. Endotherms are sometimes called WARM BLOODED They can control their body temperature through the chemical reactions of their cells. Mammals and birds are endotherms. • Ectotherms are sometimes called COLD BLOODEDThey cannot control their body temperature. Amphibians, reptiles, and fish are ectotherms.

  6. Warm Blooded– Mammals (humans, dogs, ect), birds Vertebrates have a backbone

  7. Cold Blooded– Frogs, Fish

  8. Fish • There are three groups of living fishes: JAWLESSfishes, cartilaginous fishes, and BONY fishes. • Jawless fishes look like EELS. They have smooth, slimy skin and a round, jawless mouth. Their skeleton is made of cartilage, and they have a notochord but no backbone. Examples are lampreys and hagfish.

  9. Fish cont. • Cartilaginous fishes have fully functional jaws (like sharks) and a skeleton made of CARTILAGE. Examples are sharks and stingrays. • Bony fishes make up 95% of all fish. Bony fish have a skeleton made of BONE instead of cartilage. Their bodies are covered by body scales as well. Examples are tuna, goldfish, and cod

  10. Giant TUNA!

  11. Amphibians • Amphibians were the first vertebrates to live on LANDAmphibians breathe by gulping air into their lungs and absorbing oxygen through their skin. • Amphibians start life in the WATER, where they breathe through gills. After metamorphosis, they lose their gills and develop LUNGSand legs that allow them to live on land. • Examples are salamanders, frogs, and toads.

  12. Frog

  13. Reptiles • Reptiles evolved from amphibians by adapting to life on dry land. Reptiles have thick, scaly SKIN that protects them from drying out. • A tough SHELLkeeps reptiles’ eggs from drying out and protects the embryo. • Examples are crocodiles, turtles, snakes, and lizards.

  14. Birds • Like reptiles, birds lay amniotic eggs and have thick, dry scales. Birds are endotherms and are covered with FEATHERS. • Birds are lightweight. Their feathers are strong but lightweight, and their skeleton is fairly rigid, compact, and HOLLOW. • Examples are parrots, owls, and ducks.

  15. Duck

  16. Mammals • All mammals have mammary glands. These glands produce MILK infemale mammals.   • Mammals are ENDOTHERMS. • Mammals have a diaphragm that helps them draw air into their LUNGS. • Mammals have highly specialized teeth and fur or hair on their bodies. • Mammals are divided into 3 groups: monotremes, marsupials, and placental mammals. Monotremes lay eggs instead of bearing live young. Marsupials give birth to live embryos that climb into their mother’s pouch until they are more developed. Placental mammals develop inside the mother. Mothers nurse their young after birth. • Examples are raccoons, elephants, dolphins, gorillas, and humans.

  17. ALL mammals have hair & teeth…and give birth to live offspring!

  18. Independent Practice Remember you get credit for the IP NOT for your notes!!!!! IF you DO NOT complete your IP, you will get a ‘0’ as your for this lesson!!! • Answer ALL independent practice questions • What is not done is homework!!!10point in-class assignment grade! • Remember, keeping up with the IP makes sure you know all the material for the quizzes/tests AND it improves your grade!

  19. Tuesday 6.4.2013 Week 38 Pick up Chap 30 Fish & Amphibians Packet! • Agenda • Bell Ringer (5min) • Announcements + Directions (5min) • Section 30.1 Reading + Fish worksheet (40min) • Objective: Describe the structural adaptation of fishes to their environment. • Bell Ringer Describe the 3 groups of living fish . Give one example of each. • Take out yesterdays notes! Did you get your stamp? 10pts! • EXTRA CREDIT  Up online at harlanfalcons.org! DUE FRIDAY!!!!

  20. Turn to pg. 793 • Using your text, read along and fill in each statement as you go. 1. All vertebrates are in the phylum __________ and fish, amphibians, reptiles, birds, and mammals are in the subphylum _______________ 2. Vertebrates are bilaterally symmetrical, coelomate animals with endoskeletons, closed ____________ systems, complex __________, and efficient __________ systems. 3. If you compared the number of fish species to the number of all other vertebrate species combined, there would be more species of _________ Chordata Vertebrae circulatory Brains respiratory fish

  21. Continue reading about the life and adaptations of fish while answering the questions on your handout! Independent practice! Use pgs. 793-802(NOT group work!) #4 Agnatha #11 Osteichithyes Questions #16-19. If the statement is false make sure you correct it! *ONLY CHANGE THE italicized word! ex.) Harlan high school is located in Detroit. Answer: False; Chicago **Finish question #1-20 (pg.11 &12) by the end of class! **Move on to Amphibians (pg.13)if you finish early!
