10
Name the three classes of fish
11
What are Classes Agnatha, Chondrichthyes, and
Osteichthyes?
12
Give me two examples of jawless fish (Agnathes)
13
What are Hagfish and Lampreys?
14
Tell me three well developed senses a shark has.
15
What are sharp vision, nostrils for smell, a
lateral line system and auditory organs?
16
There are three families of bony fish. What are
they and how are they named?
17
What are ray-finned, fleshy-finned and lobe-
finned? They are named after their fin
arrangement.
18
Why do sharks sink in the water as opposed to
salmon?
19
Sharks are denser than water therefore they sink
when they stop swimming. A salmon has a swim
bladder which controls its buoyancy preventing it
from sinking.
20
What does the name Amphibia refer to?
21
The name Amphibia means two lives. This refers
to the larval or tadpole stage, where they live
in water and the adult or frog stage, where they
live primarily on land.
22
Why must Amphibians stay near water?
23
They need water to reproduce and exchange gases.
24
Give three examples of Amphibians.
25
What is a salamander, a frog and a toad?
26
What adaptations help frogs avoid being eaten by
large predators?
27
What are camouflage and skin glands which secrete
a distasteful, often poisonous, mucus?
28
Of the three types of reproduction which one
describes the majority of amphibians?
29
What is oviparous, which means they lay eggs that
hatch outside the mothers body?
30
Give me four examples of Reptiles.
31
What are lizards, snakes, turtles and
crocodilians?
32
Why do reptiles have scales?
33
The scales waterproof the skin and help prevent
dehydration in dry air.
34

• ________ are the most diverse reptiles alive
  today. Snakes are ___________ and a number of
  adaptations help them hunt prey.

35
What are lizards and carnivores?
36
Name three general characteristics of Reptiles.
37
Reptiles have scales to prevent water loss. They
have an amniotic egg which allows them to survive
on land, and they are exothermic.
38
How do reptiles control their body temperature?
39
Reptiles are ectotherms which means they absorb
external heat rather than generating their own.
40
What are two things birds and reptiles have in
common?
41
Two similarities are an amniotic egg and scales.
42
Birds are able to generate heat through metabolic
energy. Once they generate this heat, how do they
stay warm?
43
Feathers and a layer of fat provide insulation or
keep them warm.
44
How is the anatomy of birds modified for flight?
45
Several organs are absent in birds (teeth, an
ovary etc.) reducing their weight. Also their
bones are honeycombed making them strong but
light.
46
What type of reproduction takes place with birds?
47
Birds fertilize internally and are oviparous,
meaning they lay their eggs outside of the
mothers body.
48
Why is flight advantageous for birds?
49
They can locate food from an aerial view
improving their hunting ability. They can catch
flying insects which are abundant and nutritious.
Flight allows them to escape predators. Also it
allows migration, where birds can seek out
different food resources and seasonal breeding
areas.
50
How many species of mammals are on Earth today?
51
There are about 4500 species of mammals on Earth
today.
52
What are 3 characteristics which differentiate
Mammals from all other vertebrates?
53
Vertebrates of class Mammalia have hair, mammary
glands, larger brains and differentiated teeth.
54
What are the three major subclasses of mammals?
Give an example of each.
55
They are monotremes (echidinas), marsupials
(kangaroos), and plancental mammals (zebra).
56
Monotremes are the only living mammals that
_______________. Marsupials have a maternal pouch
called a ______________.
57
Monotremes lay eggs. Marsupials have a marsupium.
58
Daily Double!!
59
How many orders of placental mammals are there?
To which order do humans belong?
60
There may be as many as 24 separate orders of
placental animals. We belong to the order
Primates.
61
These are commonly called tunicates
62
What are Urochordates?
63
What are the three subphyla of Phylum Chordata?
64
Vertebrates make up one subphylum. The other two
subphyla are made up of the invertebrates,
urochordates and cephalochordates
65
Why are cephalochordates known as lancelets?
66
They are known as lancelets due to their
bladelike shape.
67
What is a notochord? What is it replaced by in
vertebrates?
68
A notochord is a long flexible rod of mesoderm
found in all chordates. In vertebrates it is
replaced by vertebrae of backbone.
69
What are the four characteristics of all
Chordates?
70
What is a notochord, pharyngeal slits, a hollow,
dorsal nerve cord, and a post anal tail?
71
Final Jeopardy
How do we group together / differentiate between
the seven classes of Vertebrates?
72
The first three groups are fishes. Class Agnatha
are jawless where as the other two have jaws.
The other two classes can be separated based on
their skeletal arrangements (cartilage vs. bone).
The four other classes are all tetrapods,
meaning they have two sets of limbs. Reptiles,
Birds and Mammals can be separated from
Amphibians as they all are amniotes.
