AMPHIBIANS & REPTILES VOCAB

a venomous snake that has two, large mobile fangs at the front of the mouth VIPER

the aquatic, fishlike larva of a frog or toad TADPOLE

A snake that kills its prey by crushing & suffocating it CONSTRICTOR

A 3rd eyelid found under the lower eyelid of many vertebrates NICTITATING MEMBRANE

The bottom, or ventral portion, of a turtle’s shell PLASTRON

A membrane that attaches the small intestine to the abdominal wall MESENTERY

The ability of an organism to drop a body part & usually regenerate a new one AUTONOMY

A sound-sensing membrane TYMPANUM

A shieldlike plate that covers the cephalothorax of some crustaceans and reptiles CARAPACE

One of a varied group mostly extinct reptiles that lived millions of years ago DINOSAUR

slide2

11. a membrane that is attached to a vertebrate embryo & that encloses the yolk & thus stores energy reserves for the developing embryo

yolk sac

12. a hard protein that forms hair, bird, feathers, nails, & horns keratin

13. an animal that can regenerate body heat thru metabolism & can maintain a constant body temp despite temp changes in external environment endotherm

14. an olfactory sac that opens into the mouth & is highly developed in reptiles Jacobson’s organ

15. an organism that needs sources of heat outside itself ectotherm

16. a horny or chitinous plate that makes up part of the exoskeleton in armadillos, turtles, fishes, etc. scute

USE YOUR TEXTBOOK TO LOOK UP THESE DEFINITIONS. THEY ARE IN CHAPTERS 19 & 20. DO NOT JUST WRITE THE CLOSEST WORDS TO THE VOCAB WORD. READ BEFORE AND AFTER & USE THAT INFORMATION TO HELP DEFINE THE WORD. The order cards should have more than one sentence to define the words.

17. Tetrapod

18. Order Caudata

19. Order Gymnophiona

20. Order Anura

21. Cutaneous respiration

22. Buccopharyngeal respiration

23. Amplexus

24. Amniotic egg

25. Secondary bone (secondary palate)

26. Pit organs

27. Order Squamata

28. Order Crocodilia (Crocodylia)

29. Order Chelonia

slide4

17. tetrapod- animal that has 4 muscular limbs and feet with toes & fingers (digits)

18. Order Caudata- salamanders; possess a tail throughout life & both pairs of legs, when present are relatively unspecialized ; “Tail to bear”; also includes newts

19. Order Gymnophiona- caecilians; wormlike burrowers that feed on worms & other invertebrates in the soil; body appears segmented b/c of folds in skin that overlie seperations b/w muscle bundles; “naked like a snake”

slide5

20. Order Anura-frogs & toads; “without tail”

21. Cutaneous respiration-gas exchange across the skin

22. Buccopharyngeal respiration-gas exchange across the moist surfaces of the mouth and pharynx

23. Amplexus-in frogs, eggs are released & fertilized when the male frog (smaller frog) mounts & grasps the female  position is amplexus

24. Amniotic egg-egg that is resistant to drying; membranes form during development to protect the embryo from desiccation (extreme dryness), store wastes, & promote gas exchange; also has a leathery shell this is protective yet porous allowing for gas exchange with environment

slide6

25. Secondary bone (palate)-plate of bone that separates the nasal & mouth passageways

26. Pit organs-receptor of infrared radiation (heat) on the heads of some snakes (pit vipers); on each side of face b/w eye & nostril

27. Order Squamata-lizards & snakes; recognized by characteristics of the skull & jaws; most successful & diverse group of living reptiles

28. Order Crocodilia(Crocodylia)- alligators & crocodiles

29. Order Chelonia-turtles, tortoises & terrapins
