of red and white muscle tissue.
Question 2: Of the following statements about bioluminescence in deep-water nekton, which is/are
true? Choose all that apply.
Answer: Bioluminescent light can be used to stake out territory. Bioluminescent light can attract and lure
prey to a predator. Bioluminescence can be used to attract a mate. The majority of deep-water nekton can
bioluminesce. A flash of bioluminescent light can temporarily blind a predator, allowing the prey to escape.
Question 3: Which of the following statements about fish schooling behavior are true? Choose all that
apply.
Answer: Schools can move and appear as one large and dangerous fish, thus preventing a predator from
