Vertebrates / Invertebrates

• Brandi NunnPeach County Schools

STANDARD

• S5L1a. Demonstrate how animals are sorted into
  groups (vertebrate and invertebrate) and how
  vertebrates are sorted into groups (fish,
  amphibian, reptile, bird, and mammal).S7L1b. 
  Classify organisms based on physical
  characteristics using a dichotomous key of the
  six kingdom system (animals).

3
Vertebrate

• An animal with a backbone.
• Fish
• Bird
• Reptile
• Amphibian
• Mammal

4
Question

• What does a vertebrate have?

5
Fish

• Some fish, like sharks, have skeletons made of
  cartilage instead of bone. Fish breathe through
  an organ called gills.
• shark
• catfish
• stingray

6
QUESTION

• What do fish breathe through?

7
Birds

• Not all birds can fly. Birds have feathers, walk
  on two hind limbs, and have front limbs that are
  wings. Their bones are strong but very
  lightweight.
• ostrich
• hawk
• owl

8
Reptiles

• Reptiles breathe through lungs. Most have
  waterproof scales on their skin that keep them
  from drying out on land. Their eggs have a
  leathery or hard covering that protects the eggs
  from drying out.
• snake
• crocodile
• turtle

9
Question

• What do reptiles breathe through?

10
Amphibians

• Most adult amphibians have four legs and skin
  that is not covered with scales. Adult amphibians
  breathe with lungs. In their early stages of life
  amphibians live in water. As adults, most live on
  land.
• frogs
• toads
• salamanders

11
Question

• Give an example of an amphibian.

12
Mammals

• We belong to the group called mammals. All
  mammals feed their young milk. At one time or
  another, all mammals have at least some hair or
  fur. Most mammals have larger brains than other
  vertebrates.
• whale
• squirrel
• humans

13
QUESTION

• Give an example of an animal with a vertebrate.

14
Invertebrate

• An animal that does not have a backbone.
• Arthropods
• Mollusks
• Nematodes
• Annelids

15
QUESTION

• Does an invertebrate have a backbone?

16
Arthropods

• These animals have a tough outer skeleton,
  jointed legs, and a body made up of two, three,
  or more sections. There are more arthropods on
  earth than any other kind of animal.
• insects
• spiders
• centipedes
• lobsters
• crabs

17
Mollusks

• Almost all mollusks have a shell. The shell may
  be either inside or outside the body. Mollusks
  have three main body parts, a kind of foot, a
  tissue covering called a mantle, and a
  compartment holding internal organs. They have
  gills for breathing.
• snails
• octopuses
• clams

18
Nematodes

• These are also called roundworms. These animals
  have round bodies, a digestive system, and a
  simple nervous system. Roundworms live all over
  earth, including inside plants and animals.
• hookworms
• heartworms

19
Annelids

• These are also called segmented worms. Many
  segmented worms have eyes and other specialized
  organs, such as jaws or gills. Each of these
  animals also has a circulatory, digestive, and
  nervous system.
• earthworm
• leeches

QUESTION

• Give an example of an animal that is an
  invertebrate.
