3 Vocabulary Jeopardy Ectothermicmolt metamorphosis InvertebrateWarm- blooded incubation Cold-bloodedVertebratedecomposers

4 Ectothermic When an animal gets its heat from outside its body

5 molt To shed periodically part or all of a coat or outer covering which is then replaced by a new covering

6 metamorphosis The series of changes certain animals go through as they develop from eggs to adults; means “having a double life” in Latin.

7 Invertebrate Lacking a backbone or a spinal column

8 Warm-blooded Only two kinds of vertebrates –birds and mammals-are warm – blooded. Their blood and body stay the same temperature no matter how cold or hot their surroundings are. These animals become ill or die if their body temperature changes very much.

9 incubation To keep in a favorable environment for hatching or developing

10 Cold-blooded ☼ Almost all animals are cold-blooded. The temperature of their blood and body changes when their surroundings become warmer or colder.

11 Vertebrate Having a backbone or a spinal column

12 decomposer An organism that feeds on or breaks down dead plant or animal matter thus making organic nutrients available in the ecosystem.

13 Warm Blooded ☼ Only two kinds of vertebrates – birds and mammals-are warm – blooded. Their blood and body stay the same temperature no matter how cold or hot their surroundings are. These animals become ill or die if their body temperature changes very much. Cold Blooded ☼ Almost all animals are cold- blooded. The temperature of their blood and body changes when their surroundings become warmer or colder.

14 Vertebrates have a backbone and invertebrates do not. Without a backbone, a vertebrate’s body would collapse! The largest animals in the world are vertebrates. Insects have three pairs of legs and a body segmented into the head, abdomen, and thorax and usually having two pairs of wings. Aquatic animals have to do with the water. Terrestrial animals have to do with land. Microscopic creatures are too small to be seen by the unaided eye but large enough to be studies under a microscope. Decomposers are animals that feeds on or breaks down dead plant or animal matter. Frogs and other amphibians are vertebrates.

15 InsectsArachnidsMollusks: Octopus, squid, jellyfish, clams, oysters, snails, and slugs. CrustaceansMyriapods Centipedes and millipedes

16 Mammals Characteristics of Mammals: 1. Warm-blooded, meaning they make their own heat. 2. Have hair on their bodies. 3. Breathe with lungs. 4. Baby mammals need care and feeding—adult mammals take care of their young. 5. Female mammals produce milk for their young. 6. Most mammals live on land, although some live in the water. Whales and dolphins are mammals because they breathe with lungs. 7. Unique mammals: --Marsupials: kangaroo, wombat have a pouch to carry their young. --Duckbill platypus and echidna are the only mammals that lay eggs instead of live birth.

18 1.Hatch from eggs~ left to take care of themselves. They are “mini-adults.” 2. Cold-blooded~receive heat from outside (sun or ground). 3. Dry, thick, scaly skin 4. Shed or molt their skin several times a year. New skin grows under the old and loosens it. 5. Vertebrate~with a backbone 6. Great vision~active at night, pupils like slits to see better at night. No eyelids. 7. Go weeks without food! 8. Many colors~most often green or brown. 9. Found all over the world~ often tropical or warm areas. 10. Shape~ most long, thin with pointy snout and long tail. 11. Turtles~ the only reptile with a shell!

19 There are 4 animals classified as reptiles: lizards & snakes, turtles, crocodilians, and tuatara.

20 Some hatch from eggs and are left to take care of themselves. Some give live birth and are left to take care of themselves. Skin types: most have scales. Sharks and rays have a thick, non-scaly layer of skin. Vertebrate~ have a backbone. No eyelids Ectothermic~get heat from outside their bodies Can live in fresh or salt water Found all over the world Come in all shapes and sizes Have fins and a back tail to maneuver through water Have gills to breathe

21 Fish…

22 There are three main types of fish… Bony Sharks and rays Jawless fish

23 Hatch from jelly-covered eggs in water Go through metamorphosis and live part of their lives in water with gills and part on land Amphibians are vertebrates with backbones. Have soft, wet, slimy skin with glands to keep it moist so it doesn’t dry out Use lungs to breathe but also breathe through their skin Colors~some are bland and some are bright to warn predators that they are poisonous Ectothermic animals~get heat from outside the body Live all over the world near the water

24 Amphibians

25 Amphibians… Frog Toad Newt

26 Warm-blooded Most can fly Feathers~ body temperature, protection of body, attraction of mates, identification of species, molting Down- soft, fine feathers Bones~ feathers alone do not permit birds to fly. Birds have extremely lightweight, hollow bones that aid in their flight. Hard-shelled eggs Most build nests Care for their young

27 Birds…

28 What’s the Big Idea? Animals are classified according to different characteristics, looking at what they have in common.
