Galápagos Blue Octopus Jigsaw Puzzle – Free Online

The animal behind the headlines is not the reef-dwelling blue-ringed octopus in our puzzle. M. galapagensis is a deep-water species collected near Darwin Island at about 1,773 meters (roughly 6,000 feet). A remotely operated vehicle from the E/V Nautilus first filmed it in 2015; the specimen reached the Field Museum in Chicago years later for CT scanning and formal description.

Janet Voight and colleagues named it in May 2026. The octopus is squat, short-armed, and golf-ball sized. Its coloration — pale blue above and darker pigment inside the mantle — is called reverse countershading. Researchers think that pattern may help it hunt bioluminescent prey without advertising its position to predators.

The find also forced a rewrite of how scientists define Megaleledonidae, a family once described as large-bodied Southern Ocean specialists. A single equatorial specimen showed the family is broader than textbooks suggested.

We chose a greater blue-ringed octopus (Hapalochlaena lunulata) because it is a real, recognizable octopus with unmistakable blue markings — and because press photos of M. galapagensis are not available under a license we can use on a free public website.

Blue-ringed octopuses are venomous reef animals from the Indo-Pacific, not the Galápagos. They are famous for flashing iridescent blue rings as a warning. Our jigsaw uses a well-lit underwater shot so piece shapes and colors stay clear on the board.

When official imagery of the Galápagos species is released for reuse, we can update the puzzle. Until then, we would rather be accurate than show a landscape, a brown octopus, or abstract art and call it a blue octopus.
