Final Jeopardy

What three types of glands do all mammals possess?

2

Scent glands, sweat glands, & mammary

glands

3

4

Compared to other vertebrates, mammals have heightened senses in

what two areas?

5

Hearing & smell

6

The umbilical cord and placenta in placental mammals

replace what parts of the amniotic egg?

7

Allantois, Albumen, Yolk, and Chorion

8

Why do zoologists think that the first mammals were nocturnal predators?

9

Lack of color vision, exceptional hearing & smell, and endothermy in most mammals hint at a nocturnal

existence.

12

What two animals are the only monotremes

on the planet?

13

Platypus & Spiny Echidna

14

Name 4 marsupials other than the opossum.

15

Kangaroo, wallaby, wombat, koala, sugar

glider, etc…

16

What are three unique attributes of monotremes not seen in other

mammals?

17

Cloaca/egg laying, no nipples, & electroreception

Describe how the present distribution of marsupials and monotremes on the earth came

to be.

18

191. Monotremes & marsupials first developed during the Triassic and migrated across Pangaea2. Australia, Antarctica, and India broke away from Pangaea3. Placental mammals developed in Laurasia4. Antarctica froze and India collided with Asia flooding it with placental mammals5. Australia remained habitable and isolated from the rest of the world

What is the anatomical result of the necessity of

marsupials to crawl from the vagina to the

pouch to complete development?

20

21

There are no marsupials with hooves, wings, or flippers.

They must have forearms that are able to grip in order to

climb into the pouch

22

What is the evolutionary advantage that placental mammals have over their

marsupial and monotreme cousins?

23

They can carry their young internally until

they are fully developed

24

What are the two largest Orders of placental

mammals that make up around 60% of all

mammalian species?

25

Rodentia & Chiroptera

26

How does one tell the difference between dolphins and porpoises?

27Dolphin Porpoise

Teeth Conical Spade-like

Dorsal Fin Hooked Triangular

Face Beak No Beak

28

Describe how a cow digests its food as it passes through the

ruminant stomach?

Rumen & ReticulumOmasum

Abomasum

291. Grass is eaten and moved into the rumen and then

reticulum to pick up bacteria capable of digesting cellulose

2. Grass is regurgitated as cud and chewed to help bacteria break down cellulose

3. Cud is re-swallowed and moved to omasum where water and minerals are extracted

4. Cud moves to abomasum where normal acidic digestion takes place

30

31

32

Which mammalian Order is considered to be the

simplest placental mammal Order?

33

Insectivora

34

Elephants are the sole members of which Order of mammals (think about the

nose)

35

Proboscidea

36

What are the two mammalian Orders that are considered to be completely

aquatic

37

Cetacea & Sirenia

38

Describe the difference between Artiodactyls and Perissodactyls and

explain why there are so few Perissodactyls left on the planet

39Artiodactyls – ruminant stomachs and even-toed hoovesPerissodactyls – hindgut fermenters and odd-toed hooves

Due to climate change, the food the Perissodactyls ate went away leaving mostly the low-grade grasses that Artiodactyls are able to eat. Only a few Perissodactyls were able to adapt and survive until today.

40

What is the difference between Simians and Prosimians and what is the difference

between New-world and Old-world monkeys? (Give two examples of animals in

each category)

41Prosimians – primitive, nocturnal, solitary primates such as lemurs & tarsiers

Simians – advanced, diurnal, social primates such as monkeys and apes

New-world – flat-nosed monkeys with prehensile tails that live in the Americas such as howler and spider monkeys

Old-world – narrow-nosed monkeys with vestigial or absent tails that live in Africa and Asia such as proboscis monkeys, baboons, and the apes
