Dumbo Octopus

The dumbo octopus is the deepest living octopus species known to science. It may be found in the open ocean at depths of at least 13,100 feet (4000 m) and possibly considerably deeper. The ability to survive in extremely cold water and in the absence of any sunshine is necessary for life at these great depths. Due to their rarity and the size of the deep sea, dumbo octopuses have developed particular behaviors to maximize their chances of having a successful pregnancy whenever they meet a mate. Females are able to store sperm for extended periods of time after mating with a male, and they appear to always contain eggs in various stages of development.

Dumbo octopuses utilize their arms to maneuver by slowly flapping their ear-like fins. They consume pelagic invertebrates that float above the ocean's surface since they are foraging predators. The main predators of dumbo octopuses are diving fishes and marine mammals like tunas, sharks, and dolphins because there aren't many huge predators in the deep sea. Due to their penchant for deep waters, humans are probably not a threat to these animals because they are only very seldom caught in fishing nets.
