Watch as Octopus Eats Jellyfish, Then Clings to It as Likely Weapon

A remotely operated vehicle caught the moment a rarely seen deep-sea octopus ate a jellyfish and dragged its tentacles, possibly to use for defense.

The deep sea is an environment so mysterious that even studying what animals eat can be a challenging task.

That's why scientists were baffled when a large, rarely seen octopus known as the Haliphron atlanticus was spotted clutching an egg-yolk jellyfish in its arms.

The footage was filmed 1,240 feet below the surface of the ocean in Monterey Submarine Canyon. It's existence far below sea means that much of its population size, geographic distribution, and potential threats are largely unknown.
