A. aculeatus has been described as "the only land octopus", [1] because it lives on beaches walking from one tidal pool to the next hunting for crabs. Many other octopuses can crawl short distances on land when necessary, but only A. aculeatus is known to do so on a routine basis.
Octopus cyanea in Kona, Hawaii. Octopuses live in every ocean, and different species have adapted to different marine habitats. As juveniles, common octopuses inhabit shallow tide pools. The Hawaiian day octopus (Octopus cyanea) lives on coral reefs; argonauts drift in pelagic waters. Abdopus aculeatus mostly lives in near-shore seagrass beds ...
If oxygen saturation in sea water drops to about 1–10% it can be fatal for Octopus vulgaris depending on the weight of the animal and the water temperature. [17] Ventilation may increase to pump more water carrying oxygen across the gills but due to receptors found on the gills the energy use and oxygen uptake remains at a stable rate. [22]
Researchers believe the shorter brooding period near warm hydrothermal springs increases a hatchling octopus’ odds for survival. Mystery of octopus garden in ocean’s midnight zone solved by ...
Cephalopods are thought to be unable to live in fresh water due to multiple biochemical constraints, and in their >400 million year existence have never ventured into fully freshwater habitats. [10] Cephalopods occupy most of the depth of the ocean, from the abyssal plains to the sea surface, and have also been found in the hadal zone. [11]
The octopus is one of the most unexplainable animals on the planet, contested only by the platypus, the echidna, and the angler fish. And trust us, you don't know squat about what it can do.View ...

It can be found from the intertidal zone down to 2,000 m (6,600 ft), and is best-adapted to colder, oxygen- and nutrient-rich waters. It is the largest octopus species on earth and can often be found in aquariums and research facilities in addition to the ocean.
