Enteroctopus dofleini, the giant Pacific deep-sea octopus, can weigh up to 272 kilograms and live approximately 5 years in the cold, oxygen-rich waters of the North Pacific.

Some deep-sea octopuses possess arms spanning up to 3 meters in length, allowing them to hunt across vast distances in the sparsely populated abyssal zone.
- 05
Grimpoteuthis species, inhabiting depths exceeding 4,000 meters, possess gelatinous bodies composed of 90 percent water, allowing them to conserve metabolic energy in resource-scarce environments.
- 04
Vampire squid and deep-sea octopuses share a common ancestor from approximately 270 million years ago, making octopuses older than most other modern cephalopod lineages.
- 03
Most deep-sea octopuses possess light-producing photophores along their arms and body, using bioluminescence to communicate and attract prey in complete darkness below 1,000 meters.
- 02
The dumbo octopus, a deep-sea species, possesses large ear-like fins that can comprise up to 90 percent of its body length, enabling silent movement through the water column.

Pressure at 3,000 meters depth, where many deep-sea octopuses live, reaches 300 atmospheres, forcing their bodies to develop specialized proteins preventing cellular damage.
