Cichlids tend to prey on _Adult__ guppies, while Rivulus mainly prey on _ juvenile __ guppies.
aAdult; juvenile
The cichlid will have a marked visual bias towards the brightly colored, adult, male guppies and
they tend to prefer adult fish than juvenile one and adult are easy to spot when compared to
young fish, whereas the killifish Rivulus hartii will prey mainly on juveniles and is not a predator
on adult guppies due to their size restriction.
4. Which of the following options best summarizes Endler\'s greenhouse pond experiment?
B. Differences in the hunting patterns of predators.
Endler in his experiment has grown guppies from 18 locations in 11 different streams in artificial
ponds in a greenhouse for about 6 months and then divided them into 10 greenhouse ponds.
Added single cichlid to four ponds and half a dozen Rivulus to other ponds and after five and 14
months, he sampled male guppies from his ten populations to count their spots. The summary of
greenhouse experiment showed that evolution of phenotypes in response to changes in the
balance of sexual reproduction as well as predation selection
