A scientist from Washington state is excited after spotting what she believes to be a seven-arm octopus, typically found in the Atlantic Ocean, along the coast of B.C. The discovery was made in August when Kathleen Durant, a resident of Pender Island, stumbled upon a large, red jellyfish-like creature while walking her dog on the beach. Upon closer inspection, she noticed an eye on the mysterious animal.
Seeking identification, Durant shared images of the creature on the Field Naturalists of Vancouver Island Facebook page, where marine biologist Casey Cook recognized it. Cook explained that based on the suction cups on its arms, it was an octopus, not a squid. The specific species, however, remained a puzzle.
After thorough research and comparison of images, Cook identified the creature as a seven-arm octopus, scientifically known as Haliphron atlanticus or septopus. Despite its name, the species actually possesses eight arms, with males concealing one arm, called a hectocotylus, for breeding purposes. While primarily an Atlantic species, sightings of seven-arm octopuses on the Pacific coast have been sporadically reported in recent years.
The presence of these octopuses on the Pacific coast remains a mystery, with changing climates and currents potentially influencing their migration. Cook suggested that these creatures might have been transported through ballast water or other means, or they could be native to the area but have not been extensively studied.
Although the likelihood of the octopus being a Pacific species is low, Cook emphasized that it could be adapting to its new environment. She noted that the specimen appeared healthy and intact, indicating its well-being. Ongoing research in the deepest regions of the Salish Sea may shed light on the presence and behavior of these fascinating creatures.
