Common Octopus
Scientific Name : Octopus vulgaris
Status : Least Concern (IUCN)
On view at Aquarium in : Skellig Michael Tank
The common octopus is renowned for its intelligence, problem-solving abilities, and remarkable adaptability. Often called the ‘escape artist’ of the sea, this cephalopod is capable of solving puzzles, navigating mazes, and even using tools. With a highly developed nervous system and an impressive ability to camouflage, the common octopus is one of the ocean's most fascinating creatures.
Quick Facts
Did You Know?
- Incredible Intelligence: The common octopus is widely regarded as one of the smartest invertebrates. Researchers, including those from the Smithsonian and National Geographic, have documented octopuses solving puzzles, navigating mazes, and even opening jars to retrieve food. Their intelligence allows them to manipulate their environment in ways few other marine animals can.
- Master of Camouflage: Octopuses can change both their skin colour and texture to blend seamlessly into their surroundings, thanks to specialised pigment cells called chromatophores. This allows them to avoid predators, ambush prey, and communicate with other octopuses. National Geographic has highlighted how octopuses use their camouflage as a sophisticated form of survival.
- Tool Use: In a groundbreaking discovery, researchers observed octopuses using coconut shells and other objects as tools for shelter—a rare behaviour among animals. The common octopus can carry these shells with them, creating portable protection that demonstrates their impressive cognitive abilities.
- Three Hearts & Blue Blood: The common octopus has three hearts—two pump blood to the gills, while the third pumps it to the rest of the body. Their blood is blue due to the presence of hemocyanin, a copper-rich protein that transports oxygen more efficiently in cold, low-oxygen environments like the ocean.
- Flexible Bodies: With no bones, the common octopus can squeeze through incredibly small spaces. Their soft bodies, combined with their intelligence, make them notorious escape artists. Some have been known to escape from enclosures by pushing through tiny gaps or manipulating locks.
- Short Lifespan but Fast Learners: Despite their short lifespan of 1-2 years, octopuses are fast learners, capable of observing and mimicking behaviours. Studies have shown them remembering solutions to problems and using past experiences to their advantage in new situations.
