An octopus is a skilled mimic and artist of camouflage. In order to deceive a predator, he can morph into unique shapes, change color and texture, and even alter his behavior to make a quick escape.
One such example has been documented on video. This octopus changes into the silhouette of an ocean rock and scoots across the sandy sea floor. And although this behavior is observed in the open, the octopus matches his speed with the angles of light in the water in order to keep his disguise undetected.
Octopuses can also puff up their body to appear larger than reality, turn white, squirt ink, zigzag through the sea and blend their body to the texture and color of nearby coral.
