his photograph shows a Common octopus, Octopus vulgaris (Cuvier, 1797). This species is found globally in all tropical and temperate seas. It’s trying to imitate the surrounding rocks using its amazing ability of camouflage. Octopuses contain specialized cells to be able to change the coloration and structure of their skin within seconds to hide from potential predators. The so called Chromatophores, colour cells, are responsible for the pigmentation and can be expanded or contracted to shift coloration. Irridophores reflect light and can enhance the effects of coloration change. The third types of cells responsible for the camouflage are Leucophores, which are “white cells”. They serve as background. Muscle contractions can change the skin texture to help the octopus merge into the surrounding structures. Their extremely flexible body enables the animal to fit in the smallest holes and crevices. Reef Octopuses are usually encountered solitary, unless they mate. Octopuses feed on crabs, fish and scallops and are usually encountered solitary, unless they mate. After mating the female takes care of the eggs starving in till they hatch and dies shortly after.
