Researchers have captured footage of a mysterious species of deep sea cephalopod off the coast of Hawaii.
There is so much we don't know about the ocean's depths that we actually have a more complete picture of the surface of Mars than we do of the animals living at the bottom of the sea.
This latest video, which was recorded by the National Oceanic and Atmospheric Administration, shows a rare species of cephalopod known as the whiplash squid gliding through the depths.
The animal, which has rarely been seen alive, is able to propel itself at considerable speeds by drawing water in through its pair of peculiar red 'lips' and then ejecting it.
