Question 3

Ectotherms

Answer 3

an animal that is dependent on external sources of body heat

Question 4

Lateral Line

Answer 4

a visible line along the side of a fish consisting of a series of sense organs which detect pressure and vibration.

Question 5

Gills

Answer 5

the paired respiratory organ of fishes and some amphibians, by which oxygen is extracted from water flowing over surfaces within or attached to the walls of the pharynx

Question 6

Question 9

Swim Bladder

Answer 9

a gas-filled sac present in the body of many bony fishes, used to maintain and control buoyancy

Question 10

Amphibians

Answer 10

a cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, and salamanders. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage

Question 11

Lungs

Answer 11

each of the pair of organs situated within the rib cage, consisting of elastic sacs with branching passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed. Lungs are characteristic of vertebrates other than fish, though similar structures are present in some other animal groups.

Question 12

Tadpole

Answer 12

A tadpole is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestria

Question 13

metamorphosis

Answer 13

the process of transformation from an immature form to an adult form in two or more distinct stages.

Question 14

Caecilians

Answer 14

Caecilians are a group of limbless, serpentine amphibians. They mostly live hidden in the ground and in stream substrates, making them the least familiar order of amphibians

Question 15

Question 19

Amniotic Eggs

Answer 19

Question 20

Turtles

Answer 20

Turtles are diapsids of the order Testudines characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. “Turtle” may refer to the order as a whole or to fresh-water and sea-dwelling testudines. The order Testudines includes both extant and extinct species

Question 21

Tortoises

Answer 21

Tortoises are reptile species of the family Testudinidae of the order Testudines. They are particularly distinguished from other turtles by being land-dwelling, while many other turtle species are at least partly aquatic

Question 22

Crocodiles

Answer 22

Crocodiles or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodylinae, all of whose members are considered true crocodiles, is classified as a biological subfamily
