Ultimately, this level of dedication is extreme even for octopuses. When they returned the next month, they noticed that she was guarding a clutch of eggs. The longest previously known marine creature is the lion’s mane jellyfish — its tentacles can be up to 120 feet long.

Unlike some shallow-water octopuses that have a planktonic stage, G. boreopacifica pop out as small but complete versions of their parents, giving them a greater survival boost in the dark and lonely deep sea. And despite the fact that little is known about the deep-sea dwellers, scientists speculate that the baby octopuses’ long development period is due to the slow metabolism that is brought on by colder temperatures (which means that the cold waters are likely a contributing factor to the mother’s sparse eating habits).
