19. In an amphibian, the pumps blood out of the heart.

20. In amphibians, one circulatory loop carries blood from the heart to the

, while a second loop carries blood to the rest

of the body.

21. Salamanders are members of the order .

Read each question, and write your answer in the space provided.

22. How is a caecilian adapted to its lifestyle?

23. What enables a leopard frog to keep its skin moist? Why is moist skinimportant for this animal?

24. Trace the circulation of blood through the amphibian heart.

25. Describe one example of parental care in amphibians.

25. Members of Myxini and Actinopterygiiuse external fertilization, where the

male releases sperm as the female

releases eggs. Members of Chond-

richthyes use internal fertilization, in

which the male transfers sperm into

the females body with claspers.

26. Answers include the following: sense

of smell (detects chemicals withnostrils); lateral-line system (detects

vibrations in water); vision; sensitive

to electric fields.

27. Deoxygenated blood enters the sinusvenosus and then moves into the larger

atrium. Contraction of the atrium

moves the blood to the ventricle, the

main pumping chamber of the heart.

The ventricle pumps blood through

the conus arteriousus and eventually

to the gills.

28. Jaws allow fish to seize and manipulateprey; paired fins increase stability and

maneuverability.

29. Cartilaginous fishes either keep movingto maintain a vertical position or store

large amounts of low-density lipids.

Bony fishes have a swim bladder,

which contains a mixture of gases

from the bloodstream and regulates

the amount of gas in the body to

adjust body density.

30. (a) 1. bony fish; 2. mammals;3. Myxini; 4. Aves; 5. cartilage;

6. yes (b) all of them (c) Vertebrata

(d) aquatic (e) The skeleton is

composed of cartilage.

21. Caudata22. Caecilians are blind and legless. They

have teeth for capturing and consuming

prey, and chemosensory tentacles for

detecting prey. All of these are adapta-

tions for a burrowing lifestyle.

23. Mucous glands embedded in the skinsupply a lubricant that keeps the skin

moist. This moist surface is necessaryfor cutaneous respiration.

24. Oxygen-poor blood from the bodyenters the right atrium. Oxygen-rich

blood from the lungs enters the left

atrium through the pulmonary veins.

The blood from both atria enters the

ventricle, which pumps the blood to

the conus arteriosus and then to the

lungs and the body. Oxygen-poor is

sent to the lungs. Oxygen-rich blood

is sent to the body.

25. The male Darwins frog broods theeggs in his vocal sacs where they

hatch and undergo metamorphosis.

Female gastric-brooding frogs swallow

their eggs, which hatch and mature in

the stomach. Females of some species

sit on their eggs until they hatch.

24. During inhalation, the floor of themouth drops and the nostrils open. Air

is then pushed into the lungs as the

floor of the mouth is raised and the

nostrils close.

25. Accept four of the following: metamor-phosis; moist, thin skin without scales;

feet that lack claws; gills, lungs, and

skin for respiration; eggs laid in water

or moist places; external fertilization.
