Common Octopus

The common octopus (Octopus vulgaris) can be found in warm and temperate seas throughout the world. It is the best known of all octopus species, although shy and usually hiding out along the rocky bottoms of the water. It is remarkable for its ability to change its skin color very fast, as well as for its alleged intelligence.

The caption reads in the original French: Pieuvre commune (Octopus vulgaris).
