Common Octopuses, Octopus vulgaris

Description & Behavior

Common octopuses, Octopus vulgaris (Cuvier, 1797), reach between 30-91 cms in length and, like other octopus species, they have eight arms with numerous suckers and no internal shell. It is thought that this species has a number of subspecies, but they have not yet been taxonomically classified.

World Range & Habitat

Octopus vulgaris are found worldwide in tropical and temperate waters. They are abundant in the Mediterranean Sea, off the coast of Japan, and in the Eastern Atlantic in coastal waters between 1-200 m.

Feeding Behavior (Ecology)

Common octopuses, like other octopus species, discard the remains of their bivalve and crustacean prey just outside their lairs into piles called middens. These piles have proven useful to scientists to study the feeding habits of the common octopus. The piles also make it easier to spot an octopus lair and therefore perhaps an octopus.

Life History

Common octopuses lay about 100,000-500,000 eggs, each about the size of a grain of rice, during each breeding cycle that hatch and live in the plankton for 1.5-2 months. The juveniles that don't get eaten as part of the planktonic food web can live for up to 1.5 years.

Conservation Status & Comments

Octopus vulgaris is one of the most common octopus species commercially fished for food and for the aquarium trade. Between 10,000 and 20,000 metric tons of common octopuses are caught by commercial fisheries yearly using unbaited octopus pots. The empty pots are simply used to attract unsuspecting octopuses as seemingly safe havens.

Help Protect and Restore Ocean Life

Help us protect and restore marine life by supporting our various online community-centered marine conservation projects that are effectively sharing the wonders of the ocean with millions each year around the world, raising a balanced awareness of the increasingly troubling and often very complex marine conservation issues that affect marine life and ourselves directly, providing support to marine conservation groups on the frontlines that are making real differences today, and the scientists, teachers and students involved in the marine life sciences. Join us today or show your support with a monthly donation.

With your support, most marine life and their ocean habitats can be protected, if not restored to their former natural levels of biodiversity. We sincerely thank our thousands of members, donors and sponsors, who have decided to get involved and support the MarineBio Conservation Society.
