The Seven-Arm Octopus (Haliphron atlanticus) is one of the largest octopus species, following the Giant Pacific Octopus and appears to have only 7 arms. In reality, it is the male that has 1 arm in a coiled sac beneath the right eye and this arm is often overlooked. The Seven-Arm Octopus is typically found in the Pacific and Atlantic Oceans and tends to stay at a water depth of 3,000 ft (914.4 m). Seven-Arm Octopuses are not picky and will generally eat anything in addition to crustaceans, fish, and bivalves. They are currently listed as least concern to extinction.
The Seven-Arm Octopus has an overall length between 9.5’-11.5’ (2.9-3.5 m), mantle length of 15.75”-27.6” (40-70 cm), and weight of 135-165 lb (61-75 kg). The typical lifespan of the Seven-Arm Octopus is between 2-10 years.
