They largely reside within the ocean’s twilight zone the place gentle not often reaches, sometimes thought-about 650 to three,000 ft under the water’s floor.
“It was tremendous thrilling for me to see this species that I had solely seen as soon as earlier than,” Haddock stated. “It is usually attention-grabbing that this octopus is among the largest identified species, but it reaches these sizes [on] a gelatinous weight loss program.”
