In a hypothetical environment, fishes called pike-cichlids are visual predators of algae-eating
fish, i.e., they locate their prey by sight. If a population of algae eaters experiences predation
pressure from pike-cichlids, then which of the following should not be observed in the
algae-eater population over the course of many generations?
a. The algae eaters may become nocturnal (active only at night).
b. Coloration of the algae eaters may become drab.
c. The algae eaters may become sexually mature at smaller overall body sizes.
d. The algae eaters may become faster swimmers.
e. Female algae eaters may become larger, bearing broods composed of more, and larger,
young.
