In contrast, when the octopus is in a relaxed state, the chromatophores will retract into the elastic sac. [6] As these chromatophores interact with their environment, it enables the octopus to select, at any time, a particular body pattern. This enables it for instance to camouflage itself and hide from their predators.
Octopuses have many different adaptations in order to protect themselves from predators, and many octopuses utilize similar strategies. Some employ camouflage through which they use chromatophores to change their color. Many octopuses use a projection of ink in order to startle and distract predators.
Someday, the researchers say they hope their method can be used to design military vehicles that can automatically camouflage themselves. And other research in recent years has focused on ...
Surviving in the wild is no easy feat, but thanks to evolution, many animals evade their predators with a clever deception of the eyes. Since the beginning of time animals have either adapted or ...
Many cephalopods including octopus, cuttlefish, and squid similarly use colour change, in their case both for camouflage and signalling.
