(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?
