Which predator avoidance method would best describe an octopus blending with its surroundings?

• A. Camouflage
• B. Mimicry
• C. Mechanical defense
• D. Chemical defense

Answer: (A)

Blending with the environment to avoid being seen is camouflage, a predator-avoidance strategy that relies on color, pattern, and texture matching. Octopuses can rapidly change their skin using specialized cells to shift colors and patterns and even roughen or smooth their surface to resemble the surrounding rocks, sand, or coral. This makes them harder for predators to spot. Mimicry would involve imitating a specific other organism or object to deceive a predator, which is different from simply blending in. Mechanical defense refers to physical armor or structures like shells or spines, which an octopus doesn’t rely on. Chemical defenses involve toxins or smells to deter predators, not blending in.
