This species is difficult to describe because it changes color and texture to blend into its surroundings, using specialised skin cells known as chromatophores.

The Caribbean reef octopus lives in hidden, rocky lairs that are difficult to locate.

This octopus does not live in its lair for its entire life; instead, it moves often except when caring for eggs or young.

The Caribbean reef octopus feeds on crabs, shrimp, lobsters, polychaetes and a variety of fish.

The octopus's ability to remember where a foe resides and then avoid it is considered to be an intelligence trait.

The Caribbean reef octopus has also been known to learn from others of the same species and some have disguised themselves as algae or coconuts to avoid predatory detection.

This octopus, while not considered very aggressive, will show cannibalistic qualities if individuals are kept too close to one another in captivity.
