question

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, which of the following should least likely be observed in the algae-eater population over the course of many generations?

category

biology

options

  1. Selection for larger female algae-eaters, bearing broods composed of more, and larger, young
  2. Selection for drab coloration of the algae-eaters
  3. Selection for algae-eaters that reproduce more frequently
  4. Selection for algae-eaters with smaller eyes
  5. Selection for algae-eaters that become sexually mature at smaller overall body sizes
  6. Selection for algae-eaters that can camouflage with algae
  7. Selection for algae-eaters that feed on a different type of algae
  8. Selection for nocturnal algae-eaters (active only at night)
  9. Selection for algae-eaters with faster swimming speeds
  10. Selection for algae-eaters that can burrow in the sand
