• Does this clue eliminate any of the living things
  from the list? Why or why not?

  microorganisms.

  from the list? Why or why not?

6

• The Sunflower is a photosynthetic plant.
• Remember that photosynthesis is the process by
  which energy from the sun (sunlight) is used to
  drive reactions within plants (and some other
  organisms) so that they can create food in the
  form of carbohydrates.

  creatures on our list? Which one(s)?

  creatures They are unable to move.
• Are the Paramecium and the Bacteria immobile
  creatures? Why or why not?

• Weve eliminated some of the organisms from the
  list because they belong to other kingdoms.

21
Clue 5

• The mystery creature belongs to the class
  Mammalia.

22

• Members of the same class have more in common
  with each other than do members of a kingdom,
  phylum, or sub-phylum.

• Lets describe the main characteristics of the
  class mammalia.

23
One characteristic of mammals is that they are
warm-blooded (endothermic). What does that mean?
Endotherms have processes that keep their bodies
at a constant temperature no matter how hot or
cold the surroundings may be.
Birds and mammals are endothermic. Other
organisms are exothermic. What does that mean?
24
Exotherms

• Exothermic organisms are those organisms that
  allow their body temperature to vary with the
  ambient temperature.
• Exothermic organisms include invertebrates, fish,
  amphibians, and reptiles.

25
Which creatures remaining on our list are
exothermic?
26
Mystery Creature

• Alligator
• Leopard
• Paramecium
• Coyote
• Jellyfish
• Lion
• Frog
• Sunflower
• Parrot

• Anteater
• German Shepherd
• Bat
• Goldfish
• Mushroom
• Timber Wolf
• Tiger
• Bacteria
• Ostrich

27
One special characteristic of mammals is their
body covering. What covers the body of a mammal?
Hair or fur
Are there any creatures left on the list that
have a different body covering?
28
Mystery Creature

• Alligator
• Leopard

• Jellyfish
• Lion
• Frog
• Sunflower
• Parrot

• Anteater
• German Shepherd
• Bat
• Goldfish
• Mushroom
• Timber Wolf
• Tiger
• Bacteria
• Ostrich

29

• The parrot, alligator, goldfish, frog, and
  ostrich are not mammals. They belong to 4
  different classes.
• Members of the same class have more in common
  with each other than do members of a phylum.

30
Another special characteristic of mammals is the
way they nourish, or feed, their young. How do
mammals feed their young?

• Mammals feed milk to their young

31
Lets review the characteristics of mammals

• are endothermic
• have hair or fur
• feed milk to their young

Mammals
Are the remaining creatures on our list mammals?
32
Clue 6

• The mystery creature belongs to the order
  Carnivora.
• What is a carnivore?

33

• Animals that belong to the order Carnivora are
  those animals that feed upon flesh.
• Anteaters and bats are not Carnivores. They
  belong to the order Insectivora.
• What do you think insectivores eat?

34

35
Clue 7

• The mystery creature belongs to the Canidae
  family.

36
Members of the Canidae Family are described as
having these traits
Large Ears

• Long snouts, large ears, and bushy tails.
• Contain 5 toes on forefeet and 4 toes on their
  hind feet. Legs are well adapted to run.
• The toes on these creatures contain
  non-retractile claws.

Long Snout
37

• Cross off the other members of my family now
  because they do not belong to the Canidae family.

I have retractile claws, and so do other members
of the Felidae family.

39
Clue 8

• The genus of the mystery creature is Canis.

40

• Genuses do consist of very similar groups, but
  the groups within the same genus generally do not
  breed with one another.
• Wild and domestic dogs are members of the Genus
  Canis.
• Does this eliminate any of the creatures
  remaining on our list?

41
Clue 9

• The final clue is the species of the mystery
  creature.
• The species of the mystery creature is Lupus.

42
Species (Lupus)

• Members of the same species share many common
  characteristics, and they also breed with one
  another.
• Our mystery creature is wild, hunts in packs, and
  is the largest of all canines.

43
Still unsure?

• Final Clue!
• Red Riding Hood wasnt very happy when this
  creature ate her grandmother!!!

44

• The timber wolf is our mystery creature. Timber
  wolf is the organisms common name.
• The scientific name of the timber wolf consists
  of the genus and species name Canis lupus.

46
Classification

• You have just identified an organism using the
  taxonomic classification system.
• Classification is the identification, naming, and
  grouping of organisms into a formal system.
• It was developed by a man named Carl von Linnaues
  in the 1750s.

47

• Classification is important for so many reasons.
  Here are a few
• It is a way to learn and gain knowledge.
• One can gain information about a new species by
  looking at the similarities and differences it
  has with other species and those in its taxonomic
  categories.
• Because there are so many different kinds of
  organisms, it is important to arrange them in an
  orderly manner.
• This way, biologists all over the world can be
  sure they know the exact organism that is being
  examined and discussed.
