Term Definition
Bird warm-blooded vertebrates with feathers.
Feathers keep the bird warm and dry
Mammal Warm-blooded , vertebrates with fur or hair.
reptile Cold-blooded vertebrates that live on land.
dry, scaly, skin.
breath through lungs.
amphibian Cold water vertebrates that spend some of their lives in water and part on land.
Breaths through its skin.
skin is moist
Examples are frogs, toads, and salamanders.
cold-blooded body temperature changes with their surroundings.
warm-blooded animals whose body temperature does not change much. They get heat from breaking down food. Examples are mammals, birds
vertebrate A back bone. A back bone allows larger and heavier animal to move about
How are you like fish, frogs, birds, and mice? we all have a backbone
How is a vertebrate different for an invertebrates? a vertebrate has a backbone and an invertebrate does not have a backbone
Tell 2 reasons why a backbone is an important part of the vertebrate's body: 1.supports the animal's body
2. it allows larger and heavier animal to move about
If your bay temperature does not change much or it is a constant body temperature, what kind of animal are you? warm blooded
How do warm blooded animals get heat? from breaking down food
If you cannot keep a constant body temperature what are you? cold blooded
Where do cold-blooded animals get heat? from outside their bodies
How many classes of vertebrates are there? 7
Name the 7 classes of vertebrate? amphibians, birds, bony fish, fish, jawless fish mammals, reptiles
Name the three classes of fish? bony fish, cartilaginous fish, jawless fish
What are the skeletons of jawless and cartilaginous fish made of? cartilage
Name two places that you have cartilage? tip of my nose
& my outer ears
Describe a jawless fish mouth: boneless and like a suction cup
Name a jawless fish: lampreys
Name two cartilaginous fish: sharks and rays
Name the largest class of vertebrate? bony fish
Describe the body of a bony fish: skeleton is made of bone and it is covered with scales
Name two bony fish? goldfish, tuna
Why might warm blooded vertebrates eat more often than cold blooded vertebrates? Warm blooded vertebrates maintain a constant body temperature by getting heat from the food they break down.
How are the 3 classes of fish alike? live in water & they are cold-blooded
Name 5 classes of cold-blooded vertebrates? 3 classes of fish – bony fish, cartilaginous fish, jawless fish
Name two classes of warm-blooded vertebrates: birds
Where do amphibians live? water and land
Name three amphibians: frogs, toads, salamanders
What do frog eggs hatch into? tadpoles
How do tadpoles breathe? gills
When a tadpole changes what new body part allows it to live on land? lungs
How does an adult amphibian breathe? through its skin
Why must an amphibian live near water? to keep its skin moist so it can breathe
Name the cold blooded vertebrate that lives on land? reptile
Describe a reptiles skin so I know why it can live on land? dry skin, covered in scales that is waterproof
How do reptiles breathe? through their lungs
What is the only animal that has feathers? birds
How do feathers help a bird? keeps it warm and dry
Can all birds fly? No
If a bird cannot fly name 3 traits that are also very helpful? -light, hollow bones
-powerful lungs
-strong musles
How do birds reproduce? laying eggs
What do all mammals have? warm blood
fur or hair
Name two mammals that lay eggs: duck-bileed platypus & spiny anteater
Name 3 mammals with pouches: kangaroo, koalas, opossums
Name three mammal that have offspring develop inside of them so they give birth? Humans, sheep, bats, apes,
life cycle stages of growth and change
life span how long it can live
metamorphosis this process has several separate growth stages. Butterflies and other insects go through this process.
incomplete metamorphosis growth stages that are hard to see
complete metamorphosis each growth stage looks different. Egg, larva, pupa, adult
clone an exact copy of its parent
heredity the passing of traits
inherited traits when traits are passed from parent to offspring
fertilization egg and sperm join
embryo the fertilized egg
inherited behavior a set of actions that parents pass on to their offspring.
instinct a way of acting that an animal does not need to learm
learned behavior an animal changes its behavior through experience
reproduce parents make offspring
invertebrate an animal without a backbone
vertebrae an animal with a backbone
sponge the simplest kind of invertebrate. they do not have symmetry. they live under water
cnidarian an animal with armlike parts called tentacles. Tentacles are poisonous. jellyfish and coral.
mollusks have shells and live in water. invertebrates that live in seashells
echinoderm sea urchins. has a spiny skin.
endoskeleton the internal support structure in an echinoderms.
arthropods the largest invertebrate group. has jointed legs and a body divided into sections.
exoskeleton hard body covering that protects the body of and arthropod.
examples of arthropods crabs, shrimp, insects and some spiders
insects have three pairs of legs, on or two pairs of wings, and three body sections
arachnids four pairs of legs,two body sections and fangs……..spiders and tincks
crustaceans crabs and shrimps, have two pairs of antennae and two to three body sections. the can chew.
centipedes one pair of legs on each body section.
millipedes two pairs of legs on each body section
skeletal system a vertebrate's bones
muscular system strong tissues. shorten and pull on the bones
nervous system the master control system
respiratory system brings oxygen in and removes carbon dioxide
circulatory system moves blood through the body
excretory system gets rid of wastes
digestive system break down food
