1. Mammal Study – Merit Badge
Mammal Study is one of the elective merit badges for the
William T. Hornaday awards for Boy Scouts and Varsity Scouts

2. #5 – Homework part. select and carry out one project that will influence the numbers of one or more mammals.
Jot down at least 5 things that YOU can do, then put your plan into action.
The following are my ideas, you can use them or think of your own.
Best - Protect their habitat – how can you do this?
Protect the environment – air, water, land
Reduse, Reuse, recycle, Clean up an area.
Reduce pollution

3. Ideas to improve the habitat of mammals
Car pool, trax etc. - decreases the need for roads
Nature preserves
Pick up your garbage
Make housing for different mammals
Follow the gaming (hunting) laws
Stay on the path
Leave no trace
Pick up one piece of trash a day

4. #1
Explain the meaning of "animal," "invertebrate," "vertebrate," and "mammal."
Name three characteristic that distinguish mammals from all other animals.

5. 1). Animal
A living, multicellular organism, that can move on its own and has to eat.
It is a heterotroph – consumer -
Is a fish an animal?
Yes
Is a spider an animal?

6. Do all animals move? No Example – Sponge Example – Barnacles
(These animals attach themselves to something and do not need to move because they get nutrients from the ocean tides)
So MOST animals move on their own.

7. Are plants a type of animal?No
It does not have to eat
It is an autotroph – Producer
There are some plants that DO eat.
Example – Venus fly trap
In science – there are NO PERFECT DEFINITIONS!

8. 2). What is an Invertebrate?
Without a backbone
Is a worm an invertebrate?
Yes
Is a grasshopper an invertebrate?
Is a snake an invertebrate No
Is a Lobster an Invertebrate?

9. 3). What is a Vertebrate? Something with a backbone.
Are you a vertebrate?
Yes
Is a frog a vertebrate?
Is a fish a vertebrate?
Is a bird a vertebrate?

10. A shark is flexible because his skeleton is made of cartilage
So is a shark a vertebrate?
Yes. his backbone is made of flexible cartilage – called a notochord)
Is a turtle a vertebrate?
Yes

11. 4. What is a mammal? Vertebrate With mammary glands And true hair
endotherms

12. mammary glands
Allows mammals to nurse their young

13. 5.) Mammals have - True hair
Hair (true hair)
Why don’t hair cuts hurt?
It is dead.
Short hair
Long hair

14. Some animals have hair-like growths – not true hair –
Example – Insects – spiders.
What looks like hair on a fly or a spider actually contains living parts of the animal.
That means if you cut a spider's hair it would HURT!  (er, the spider)
Spiders are not mammals

15. Some mammals have very little true hair
Example (just write down two)
– Rhinoceroses, elephants, whales, hippopotamus

16. What is an endotherm? Endotherms (warm blooded)
– Endo = into
Therm = temperature
Regulate there body temperature internally.

17. (don’t need to writ this one down) What is an ectotherm? (coldblooded)
Everything else – except birds
To get warm they must
move into the sun
To cool off they must
Move into the shade

18. Classify three mammals#2
Explain how the animal kingdom is classified. Explain where mammals fit in the classification of animals.
Classify three mammals

19. Animals Vertebrates Invertebrates Fish Protozoa Amphibians Annelids
Reptiles
Mollusks
Birds
Arthropods
Mammals

20. 3 types of Mammals
a. Placental Example - Us b. Nonplacental - Marsupial Example – anything with a pouch - kangaroo c. Egg layers – Called monotremes – Example – Duckbilled playtypus. And echidnus

21. Do whales have belly buttons?
Yes – They are placental mammals
Young grows inside mom.
The placenta grows inside mom and provides nutrients to the child

22. Marsupials – Non placental
When the young are born, they find their way to the mothers pouch.
They stay there for several weeks or months, nourished by their mothers milk
Kangaroo
Opossum
Sugar gliders.

23. Monotremes
Mammals that lay eggs.
Duckbilled platypus
echidnas

24. Classify three mammals from phylum through species
Common Name – Duckbill Platypus
Kingdom:
Animalia
Phylum:
Chordata
Class:

Blumenbach anatinus
Species: anatinus

25. Common name = kangaroo Kingdom: Animalia Phylum: Chordata

O. orca

27. #3
write a simple history of one nongame mammal that lives in your area.
Tell how this mammal lived before its habitat was affected in any way by man.
Tell how it reproduces, what it eats, what eats it, and its natural habitat.
Describe its dependency upon plants, upon other animals (including man), and how they depend upon it.
Tell how it is helpful or harmful to man.

28. What is the one mammal that fly's?
BATS

29. Where do mosquitoes lay their eggs?
Wet Areas
Do we have wet areas in Davis county
YES – THE WET LANDS!

30. Mosquito bites can cause illnesses.
Bats – Like mice and other animals can als0 carry diseases.
But are you more likely to be bit by a bat or a mosquito?

31. What else do bats eat? Insects that eat our Crops
Davis county has Farms.
What do we all need to survive?
Food?
What is the bottom of the food chain?
Plants.

32. Where do bats live? In the ceiling of Layton high

33. But what was its natural habitat before Layton High?
Caves
Tree tops
Anywhere there are insects.
Wet areas – swamps, rainforests

34. 10. Can bats see? hear? Smell? Yes – Bats have really big ears.
Bats have the best hearing of all land mammals. 
Bats hunt at night. This is called nocturnal.
Bats are not really blind (blind as a bat)
But bats do not have special night vision so they use echolocation.

35. Don’t talk with your mouth full
Some bats eat while flying (they swoop and catch insects -- eating them while they're still in the air). 
Although some bats make the squeaks needed for echolocation with their mouths,
So how do bats do echolation with their mouths full?
Make sounds with their noses. 

36. What are Nose leaves special flaps and folds of skin on their faces .
send the sounds in different directions. 
give the bats a rather odd appearance!

37. 11 ) There are 900 different species of bats
they make up one fifth of the world's mammals. 
They are the second largest group of mammals (rodents are the largest). 

38. What are the two main groups of bats?
“flying foxes” – or megabats - the large fruit eating.
Pests to people who own fruit tree orchards
Helps Spreads seeds and pollinate flowers
“microbats” - the smaller -
eat insects, blood, fish, lizards, birds and nectar.

39. Are vampire bats real?
Yea but they don’t turn into dead humans things like Dracula.
They rarely bite people and they rarely kill their prey.
They mainly feed off the blood of cows and horses. They bite the animal, causing it to bleed, them lap up a really small amount of blood.

40. #4 We will do “in class” projects to learn more about mammals
If you miss this day, you will need to do one of the following.
Visit a natural history museum. Report on how specimens are prepared and cataloged. Explain the purposes of museums. or
Write a report of 500 words about a mammal species.

41. #5 select and carry out one project that will influence the numbers of one or more mammals.
Jot down at least 5 things that YOU can do, then put your plan into action.
The following are my ideas, you can use them or think of your own.
Best - Protect their habitat – how can you do this?
Protect the environment – air, water, land
Reduse, Reuse, recycle,
Reduce pollution

42. Car pool, trax etc. - decreases the need for roads
Nature preserves
Pick up your garbage
Make housing for different mammals
Follow the gaming (hunting) laws
Stay on the path
Leave no trace
Pick up one piece of trash a day
