An octopus reproduces only once in its life, but it may have more than 100,000 offspring, depending on the species. Certain
species of penguin, by contrast, have only one chick at a time.
If some species can reproduce as rapidly as the octopus (100,000
offspring every 3 or 4 years), how is it possible that a species that has only one young at a time is equally successful?
