Question
Chapter 34.2, Problem 1HYEW
Summary Introduction
To answer:
Do sharks really need to keep swimming to stay alive?
Introduction:
Some sharks must swim constantly in order to keep the flow of oxygen over their gills. Great white sharks and the mako shark is known as ‘obligate ram ventilators’, it is most essential for them to keep moving to stay alive.

Students have asked these similar questions
Crayfish have gills but open circulatory systems, whereas squid have gills but closed systems. What does this difference tell you about each animal's average metabolic needs?
What other large surface do squid use for gas exchange, and what internal structure in the squid serves as defense?
Explain everything in three paragraphs.
O The toxin causes inappropriate firing of neurons leading to periods of rapid twitching that infected individuals experience as surnmation
leading to tetanus.
QUESTION 6
Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of
airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas
exchange compared to amphibians. Why is this?
O The more complex structure provides more surface area across which gas exchange can occur.
O A complex structure means that gases have more contact time with gases compared to a simpler structure.
O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs.
O The respiratory membranes of mammals are able to diffuse gases across them much faster than amphibians.

(1) Please examine the figure below, depicting a portion of the rete mirabile associated with the gas bladder of two fishes:
(a) One of these diagrams references a shallow water fish and the other references a deep water fish. Which diagram belongs to which type of fish? How can you tell?
(b) Many deep water fish lack swim bladders altogether! Why do you think this is? What does the presence of a swim bladder in the above deep sea fish suggest about its behavior?

- There’s lots of oxygen in water (H2O). Why can’t fish breathe that? Why do they have to breathe oxygen dissolved in the water?arrow_forwardSharks live in marine (saltwater) habitats and are osmoconformers. Based on this information which of the following is/are true (select all that apply): A. Sharks have tissues/body fluids that are isoosmotic relative to the environment B. Sharks have tissues/body fluids that are hypoosmotic relative to the environment C. Sharks devote considerable energy to osmoregulation D. Sharks do not devote much energy to osmoregulationarrow_forwardDue to human activities more carbon dioxide (CO2) is dissolving into the air, the ocean takes up more CO2 and becomes increasingly acidic. Increased ocean acidity makes it more difficult for marine animals to produce their calcium-rich hard parts. Explain three types of invertebrates that are likely to be adversely affected by an increase in ocean acidity.arrow_forward
- Elephant seals do deep dives to forage for food. The energy used by the seals in diving depends on their body composition; for example, fatter seals use less energy to swim to the surface at the end of a dive, allowing them to takelonger, more productive dives. Explain why you’d expect this to be the case.arrow_forwardA fish swims from a body of cool water into a body of warm water. As its body temperature rises, its rate of O2 consumption increases. The warm water, however is likely to have a lower concentration of dissolved O2 than the cool water because the solubility of O2 in water decreases as temperature increases. These two factors taken together, an increase in the fish's rate of O2 consumption and a decrease in the dissolved O2 concentration of its environmental water, can make it difficult for the fish to obtain enough O2 to meet its needs. The two factors can act as a two-pronged trap. Actually, however, the fish may face a three-pronged trap. How is the increase in temperature likely to affect the O2 affinity of the fish's hemoglobin, and how could the effect on hemoglobin add even further to the challenge the fish faces? Does global warming pose concerns of this sort?arrow_forwardPhotosynthetic sun-basking shark: They grow to about 4 m long, are grey or brown bodied, with all of their fins being green. Their green fins have chlorophyll, so that they can convert sunlight to energy. Has a very tall dorsal fin and long upper caudal fin because of it. They still have gills but have developed the ability to close their gills so that they can “bask” on the surface of the water for up to 10 minutes without suffocating. They still consume small fish for nutrients as well. Decide what Kingdom and Phylum these organisms would fall under and explain your reasoning. If you feel that a new Kingdom and/or Phylum needs to be created for this organism, explain why, and list basic characteristics of your new Kingdom and/or Phylum.arrow_forward
