Other methods of tracking and identification include methods like tattooing but that puts the organism at risk so photo-identification is the best way to track this species.Chromatophores, in the case of cephalopods, are neuromuscular organs that contain pigment and function differently than in most other animals. When prey is encountered, they use their arms and suckers to hold onto the prey and remove it from its burrow. A Wunderpus Octopus filmed at Lembeh Strait, Indonesia. Another function of their chromatophores is intraspecific communication which facilitates their signalling to one another.Juvenile and para-larvae octopuses also have chromatophores called founder chromatophores, which are also sac-like organs that contain pigments in their skin. Researchers usually use naturally occurring injuries and/or scars to identify individuals but this technique does not work for long term identification. There are studies that suggest that the wunderpus octopus is known to impersonate animals like the In male wunderpus octopus, their reproductive organ (penis) is relatively short but strong. Each organ contains an elastic sac containing pigment which is attached to the radial muscle of the octopus. Wunderpus' from German “wunder” meaning ‘marvel or wonder’.

The founder chromatophores are prominent in juveniles and become more masked as the octopus approaches adulthood.The wunderpus octopus has small, subraocular eyes on top of elongated stalks protruding from its mantle. The chromatophores react to stimuli and facilitate interaction with their environment. There is little to no social behavior exhibited in the wunderpus octopus. ""We visited Black Sand for the second time because we could not have imagined having better hosts than Bruce and Fung as well the number and variety of great dive sites.
In contrast, when the octopus is in a relaxed state, the chromatophores will retract into the elastic sac.As these chromatophores interact with their environment, it enables the octopus to select, at any time, a particular body pattern.
