The Indonesian mimic octopus is able to camouflage itself from predators by blending into the background. Sometimes, though, even when a predator is nearby, the mimic octopus takes on a color pattern that is not present in the immediate environment. A marine biologist of cephalopods claims that this behavior is a sign of an octopus engaging in play, meaning that the behavior does not confer any specific advantage.

Which of the following, if true, would most call in to doubt the marine biologist’s claim?

A An observational study that tracked a mimic octopus over the course of a week found that it changed the color of its skin even when there were no predators in the area.
B The color pattern an Indonesian mimic octopus assumes when a predator is nearby, but that does not match its immediate environment, has been found to parallel that of various jellyfish venomous to the octopus’s predators.

C The Indonesian mimic octopus engages in other forms of behavior that seem to serve no purpose, yet several marine biologists are reluctant to describe such behavior as play.
D Most sea species will employ some form of escape whenever a predator is in the vicinity, even if that involves solely camouflaging themselves.

E Marine biologists are not familiar with all of the environments that the Indonesian mimic octopuses inhabit, since it is known to swim into crevices deep in the ocean’s floor.


(B) gives a compelling explanation for the apparent random pattern of the octopus. It is actually the color pattern of a jellyfish that is poisonous to the predators of the octopus. In other words, the octopus is trying to trick its predators into thinking that it is something poisonous to them.
