3When an animal gets its heat from outside its body EctothermicWhen an animal gets its heat from outside its body
4moltTo shed periodically part or all of a coat or outer covering which is then replaced by a new covering
5metamorphosisThe series of changes certain animals go through as they develop from eggs to adults; means “having a double life” in Latin.
6InvertebrateLacking a backbone or a spinal column
7Warm-bloodedOnly 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.
8incubationTo keep in a favorable environment for hatching or developing
9Cold-bloodedAlmost all animals are cold-blooded. The temperature of their blood and body changes when their surroundings become warmer or colder.
11decomposerAn organism that feeds on or breaks down dead plant or animal matter thus making organic nutrients available in the ecosystem.
12Warm Blooded Warm and Cold Blooded Cold Blooded Almost all animals are cold-blooded. The temperature of their blood and body changes when their surroundings become warmer or colder.Warm BloodedOnly two kinds of vertebrates –birds and mammals-are warm –blooded.

13Vertebrates or Invertebrates... 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 bodysegmented 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 otheramphibians are vertebrates.
14Invertebrates Insects Arachnids Mollusks: Crustaceans Myriapods Octopus, squid, jellyfish, clams, oysters, snails, and slugs.CrustaceansMyriapodsCentipedes and millipedes
15Characteristics 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 takecare 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 withlungs.7. Unique mammals:--Marsupials: kangaroo, wombat have a pouch to carry theiryoung.--Duckbill platypus and echidna are the only mammals that lay eggs instead of live birth.
17Characteristics of a Reptile 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 skin4. Shed or molt their skin several times a year. New skin grows under the old and loosens it.5. Vertebrate~with a backbone6. 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!
19Characteristics of Fish 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 eyelidsEctothermic~get heat from outside their bodiesCan live in fresh or salt waterFound all over the worldCome in all shapes and sizesHave fins and a back tail to maneuver through waterHave gills to breathe
21There are three main types of fish… BonySharks and raysJawless fish
22Amphibians Hatch from jelly-covered eggs in water Go through metamorphosis and live part of their lives in water with gills and part on landAmphibians are vertebrates with backbones.Have soft, wet, slimy skin with glands to keep it moist so it doesn’t dry outUse lungs to breathe but also breathe through their skinColors~some are bland and some are bright to warn predators that they are poisonousEctothermic animals~get heat from outside the bodyLive all over the world near the water
25Characteristics of Birds Warm-bloodedMost can flyFeathers~body temperature, protection of body, attraction of mates, identification of species, moltingDown- soft, fine feathersBones~ feathers alone do not permit birds to fly. Birds have extremely lightweight, hollow bones that aid in their flight.Hard-shelled eggsMost build nestsCare for their young
